Planning For Adventures In Faceting
By Merrill O. Murphy
Introduction
If your gem-cutting history
runs parallel to that of most faceters, you will have cut a number of gems
in the various shapes of rounds, squares, rectangles, triangles, hexagons,
ovals, marquises, and hearts, or, perhaps, none of the last three. Have
you cut any unusual shapes or exotic designs? Have you cut any soft or
difficult materials? Did you cut any specialty collections (all from one
county or state, all different varieties of one mineral, etc.), created
any gem designs, or cut for competition? You mean that have not done these
things? Then, you are safely within the description of the average facetor.
If being classed as average anything makes you feel uncomfortable, then
the five parts of this article fall right down your alley.
PART 1
Faceting Gems With Real Character
Not all gem designs have equal
eye appeal for one reason or another. Some gem materials do not look their
best when cut in certain faceting designs. Some designs are used so often
that they become boring and sort of old hat. Some gem materials are cheaper
than others, and, therefore, are seen so often that we tire of them. You
can really perk your cheaper materials up with a striking design never
seen before in your local jewelry store. If free cash is your problem,
here is a way to compete with other faceters. Choose a design that yields
the most from whatever material you can afford. Of course, many of these
special designs are more difficult, and that is just fine. In meeting the
challenge, you become a better facetor without risking pricey gem material
in the process.
Where does one find a good
selection of proven designs? You simply save every design you see. If you
do not have what you need, then merely ask someone who has faceted for
years. Get some computer-operating facetor to download it from the DataVue2
files, as there are around 4,500 designs available. I have 11 loose-leaf
notebooks full of them. Give me a call at 505-275-3192. I do not have everything,
but, if I have what you want, you may borrow it long enough to make a copy.
I have a number of designs
that I find especially attractive. I will list part of that special set
below. Be aware, however, that the designs I like most will not necessarily
be the same set that you would choose. Nor, should they be. Here are a
few of those special designs that ring the bells for me.
ROUNDS
Valentine Cut
By Alton R. Walls
An 8-main design with crown
mains cut in a heart shape against a domed top.
Cartwheel Gem
My copy lists no originator.
Facets on pavilion are
vertical bars; girdle is uneven; a bright cut.
Butterfly
by Don Clark
Butterfly pattern on pavilion
shows plainly through oversize table.
Round Barion Checker
by Roscoe E. Clark
Apex crown with interesting
pattern.
SRB Checker
by Fred W. Van Sant
Apex crown with straight
rows of uniform squares - nice.
Cloud Nine
by Louis Natonek
Nine sided design with
36 crown girdle facets.
Mirrored Dome
by Louis Javit
Conventional pavilion where
crown facets are floating ovals of various sizes below a small, circular
table. Crown, as a whole, is smoothly rounded.
Princess Scintilla Cut
by Perry V. Row
Crown mains are regular
hexagons with strange, lacy appearance. Pavilion is too complex, so consider
substituting a standard round brilliant pavilion.
The Moon Beam
by Dave Miller
Crown much like the Mirrored
Dome, except each oval is made up of eight segments. Pavilion would be
better cut as on a SRB.
Eleven Split Mains Brilliant
by Ernie Hawes
Reserve for a fairly large
stone; gives lots of twinkle.
Trigoda
by Clifford D. Older
An old design that is very
modern that uses a rounded triangle with an apex crown.
Cube Illusion Triangle
- by Robert W. Strickland
A remarkable triangle with
rounded sides that features an apex crown in a different checkerboard pattern.
Mini Barion Trilliant
- by Alexandre Wolkonsky
A triangle with rounded
sides; bright. If your stone size is over 8 mm, I suggest increasing the
angle of that pavilion facets 3 and 4 by about one degree and adding facets
at indices 16, 48 and 80. For quartz, the angle should be no lower than
41 degrees. (At this point, the design becomes a full barion).
Lucifer
- by Jack Rowland
A cut-corner triangle with
a half twist. Again, if your stone is large, add small, full barion facets
at pavilion indices 96, 32, 64 at an angle of 41+ degrees.
Tripolar
- by Merrill O. Murphy
Pardon my ego, but I have
always liked this one; good for large gems. (From the Editor: This is one
of my personal favorite gemstone designs. I have rendered it about a dozen
times in various gem materials with great results, but it never seems to
become any easier.)
Jonanco Sun Cut -
by Vancouver Island Faceters Guild.
A modified triangle shape
having a crown giving the impression of a circle imposed on a step cut;
nice.
Aztec Triangle -
by Merrill O. Murphy
One of my early designs,
having chevron facets and an apex crown. The design has fair brightness,
despite too many pavilion chevrons that lose light and weaken the triangle
corners. The apex crown can be replaced by a conventional table as per
the Cardinal-Aztec Triangle, FACETS, Nov. 1987.
Trilliant
by Basil Watermeyer
There are several Trilliants.
I suggest Trilliant C. Trilliants are relatively easy to cut and are quite
bright.
Tourmaline Triangle 4
- by Sid Word
Bright, especially good
for rubellite tourmaline with the table set at right angles to the length
of the crystal. Yield is good, since the crystal outline is nearly identical
to that of the finished gem.
SQUARES, REGULAR, CUT-CORNER,
AND CUSHION
Diamond Checker
- by Fred Van Sant
Very nice checkerboard
apex crown with mini barion pavilion.
Diagonal Crown Square
- by Don Serafin
Strange barion with offset
facets.
Original Barion
- by Basil Watermeyer (South African diamond
cutter)
A design with a design
patent. This one has a very interesting background for me. The era was
the late 1960's. Donald Fogg of Fogg Jewelry Co. in Albuquerque showed
me a recent edition of a trade magazine with a rough drawing of this design.
He was interested in buying some diamonds so cut, but wanted to see firsthand
what this design looked like in a cut stone. He asked if I would try cutting
it in a lesser quality gem material. I worked out the angles and indices
and became, I think, the first American to cut the barion design. In 1970,
we moved to Winston-Salem, NC. There, I displayed some of my cut stones
in a local show. A Virginia lady facetor saw my barion cuts and fell in
love with them. At her request, I showed her how it was done. Back home
in Virginia, she wrote to me, strongly suggesting that I get the design
published. I explained, again, that the design was patented, and that I
believed it would not be ethical to publish it. She became much irritated
with my stand and eventually published it under her own name in the old
Sapphire Faceting Guide. And so it goes.....
Spin-off -
by Norman W. Steele
An interesting, easy cut
with a partially rotated table.
Square Bar-barion
- by Robert W. Strickland
This one is a very interesting
barion with step-cut crown and rounded corners. The crown corners end up
as small areas of square checkering.
Barion Checkerboard
- by Sid Word
The name describes this
fine design. The crown is composed of square checkers.
DIAMOND SHAPES AND LOZENGES
A Girl's Best Friend
- by Robert W. Strickland
A cushion-type diamond
or lozenge. Pavilion is a simple barion; nice.
FVS-175A
- by Fred W. Van Sant
A very nice lozenge design
with a diamond checkered crown and a barion pavilion.
Cushion Lozenge
- by Alexandre Wolkonsky
Brilliant-cut crown and
mini barion pavilion.
Endfire 2 -
by William R. Deazley
A brilliant-cut lozenge
that looks nice. Cutting data is specified for his unusual machine design.
Should be easy to convert to work on most machines.
DESIGNS WITH 5 TO 11 SIDES
Fiver
by Fred W. Van Sant
A five-sided design somewhat
resembling the Princess Scintilla (round), having a single-cut pavilion.
Star Of The Northwest
- by Ed Rieks
Five sides; angles for
CZ. It has an apex crown covered with diamond shapes. The pavilion is similar,
but covered with triangular shaped facets.
Honeycomb
- by Fred W. Van Sant
Six sides, crown made up
of small hexagons, table is one small hexagon, and pavilion is a fairly
complex barion. The girdle is uneven. Very nice.
Hex-diamonds
- by Fred W. Van Sant
Six sides, apex crown design
made up of interlocking diamond shapes. The pavilion is a simple mini-barion.
The Triple Sunrise
by Ruth Bronson
Six sides, with crown of
long triangles slanting upward from the corners. The table is a rounded
triangle. The pavilion is, also, and made up of long slanting triangles
originating from the girdle corners.
Eye Of The Tiger
by Robert Gray
This is a long, canoe-shaped
hexagon with a sort of brilliant-cut crown and pavilion.
Septifoil
by Paul A. Head
This one is a seven-sided
design, with a brilliant-cut crown. The culet is at the point of a seven-pointed
star.
Twirl Agadon
by Don Olsen
An unusual eight-sided
design with lots of sloping crown side triangle facets and a flower design
on the pavilion.
The Lady Bird
by Don Hartley
The crown of this one uses
unusual facet shapes. The pavilion looks like an eight-spoked wheel.
Fancy Octagon Cut
by Q. D. Howell
The table is square. The
crown features four half circles with numerous step- cut facets in-between.
The pavilion has the same step-cuts abutting against eight wheel spokes.
An unusual design!
SDGMGS Logo
by Tom Hicks
With nine sides, this one
has an odd shield shape with a, more or less, brilliant-cut crown and a
very minimum number of pavilion facets.
11 Spokes
by Walt Heitland
This one has eleven sides,
featuring a step-cut crown and a pavilion having triangular facets separating
rectangular wheel spokes. An interesting pavilion concept.
Brazen Eleven
by Al Huebler
This one, Al's last design,
might be better described as an exotic. However, he designed it as an eleven-sided
cut. The crown is partly a horizontally split brilliant, partly step cut.
The pavilion, too, has both step and brilliant features. If one looks closely,
the pavilion is an exotic bird design. Awesome!
Step Top
by Charles Covill
A cut-corner rectangle,
this design substitutes a stepped crown for the normal table. The pavilion
is an unusual barion. Length to width ratios can be varied.
Ezbar
by Robert W. Strickland
A relatively easy cut-corner
barion rectangle, but still out of the ordinary.
Commercial Tourmaline
Reference- Bruce Leininger
This is a very old cut
used in Brazil for tourmaline. It is, essentially, a common, but long step-cut,
cut-corner rectangle. When used with dark green tourmaline, latest information
indicates a single step at about 70 degrees should replace the three steps
shown (crown and pavilion) at indices 24 and 72. Dark green tourmaline
is opaque when viewed from the ends. The single step at a high angle helps
make the blackened ends less obvious.
Step Top # 2
by Charles Covill
This is a variation of
the STEP TOP (above). It places a long, narrow bar at a table position.
Barion-type Rectangle
by Jerry W. Carroll
A cut-corner rectangle,
this one has a step-cut crown and barion pavilion.
Backgammon Cut
by Robert S. Stepp and Charles Covill
This is a wonderful design,
essentially a cut-corner rectangle/barion. The crown sets this one apart.
It has a shallow apex crown made up of end-to-end triangular pennants.
If you have tired of the usual, cut this one.
CUSHIONS (ROUNDED SQUARES
OR RECTANGLES)
1.75 Cushion Cut
by Stephen W. Attaway
This one is long with a
brilliant-cut crown. The pavilion is relatively shallow with all facets
triangular.
Long Cushion Oval
by Charles W. Covill
With a length to width
ratio of 2.19, this is a very long stone design. The crown is cut in a
simple, more or less brilliant fashion. The pavilion is more complex and
has a keel.
12-Main Cushion Brilliant
by J.W. Carroll
This is a swanky design
more or less described by its title. Nice!
Circle Inside A Cushion
by Charles W. Covill
Mostly step-cut, this one
presents a fine appearance you have never seen at your favorite jewelry
store.
Una Poco Mesa
by Norman W. Steele
This one is a smoothie,
with a tiny diamond-shaped table, almost an apex design. The pavilion is
an interesting mini barion variation. An definite eye-catcher!
Almost Square Crown Facets
by Charles W. Covill
With a tiny square table,
checkerboard and slender diamond shapes on the crown, and a simple pavilion,
this one is just plain swanky.
OVAL, MARQUISE, HEART,
PEAR
In these categories, I see
little leeway for innovation. One exception is in the:
Walter Carss Cut
by Fred W. Van Sant
I would call this one a
pear design, but it could be in a category of its own. It is a difficult
design, requiring the use of a CAM preform. Girdle facets in the index
range between 33 and 63 are on a circle with the center at dop center.
Those girdle facets in the index range between 07 to 23 and 73 to 89 are,
also, on circles, but the circle centers are to right and left of the dop
center. For those who understand the preceding sentences, this is a fine
design, but I suggest that you first cut it in quartz.
THE EXOTIC AND THE ODDBALL
The Superimposition
by Merle A. Reinikka
This design features a
regular octagonal shape with bars across the crown. One of these bars is
in the table position, and all the bars are framed by triangles. Pavilion
facets are triangular. This is an imaginative design.
Zebra's Eye and Zebra's TWISTED EYE
by Walt Heitland
These are highly imaginative
designs with small tables. Both employ bar facets across the crown width.
They are not terribly complex designs, and, with care, can be cut by faceters
having a year or two experience. Do it.
FVS-169
by Fred W. Van Sant
This one is a bit tricky
and requires a CAM preform. I suppose one would call it a brilliant-cut
lozenge with a full barion pavilion. Whatever it is called, it makes a
real impression. Your jeweler has probably never seen one.
Signal Flagcut
by Herbert S. Graves
This one is a rectangle
with no table. The crown is composed of eight pennant-shaped facets running
lengthwise of the stone; half run to the left, half to the right. The pavilion
features many conventional step facets.(If you cut this design, trash the
pavilion, substituting something more imaginative.) The author gave cutting
instructions suited to the old Sapphire machine. This included a 45 degree
adapter and much needed cheating. To cut this design, you must work out
a new set of angles and indices.
Thunderbird Cut
by Norman W. Steele
This design features a
flying bird-like form on the crown of an elongated, seven-sided design
shape. It is an easy design to cut, yet distinctive.
Signet
by Wilf Ross
This is a sort of shield-shaped
design with a checkerboard apex crown and a full barion pavilion. It is
a highly unusual design and well worth trying.
Smiley And Grumpy
by Fred W. Van Sant
This pair of designs are
built around a human face shape. One of the facets define a smiling facial
expression. The other provides an angry expression. They are really quite
attractive and should not be too difficult.
The Eye
by Henry E. Larson
This is a highly imaginative
design in the shape of the human eye. There are lots of facets on the crown
and not many on the pavilion.
The Lynn Cut
by Mike Drozen
This, also, is a sort of
free form eye-shape without many facets. It is not exceedingly bright,
but it is unusual.
`S' Curve Modification #3
by Norman W. Steele
This one is similar to
the Lynn Cut, but has more pavilion facets.
Symbolic Eye
by Murrary Thompson
Another eye-shape with
a few more facets than the Lynn Cut. It is a bit more brilliant.
The Pharaoh's Eye - submitted to SAPPHIRE FACETING GUIDE
by GEMS OF THE WORLD
This is a somewhat simplified
eye design with an oval table.
Sun Valley
by Carl M. Unruh
A comma-shaped design with
brilliant-cut crown and step-cut pavilion.
ESS Worm
by Merle A. Reinikka
The name just about describes
the shape. Both crown and pavilion are step cut. Unusual.
Double Fan And Bar
by Norman W. Steele
A sort of lozenge or rude
oval shape. Five bar shapes run lengthwise on the crown, with the center
bar serving as a table. The pavilion employs only ten facets, all simple
triangles. Merle's Cut, by Merle A.Reinikka, is similar. The Opposed Bar
Cut by Gustave Mollin is somewhat similar, but the bar cuts run across
the width of the design. All three of these designs do a fantastic job
of scattering light flashes in all directions.
That about does it for this
article. Part 2 will cover the subject of cutting soft and unusual gem
materials.
