Topical Focus for This Week:
GARNET and DARK STONE CLINIC
HOMEWORK for tonight:
For each night this week, put on your thinking caps and share your experiences,
pains and pleasures in cutting Deeply colored Garnet and other Deeply
Consider the following while you compile your responses.
1. Cutting garnet and other stones in the various color saturations
2. Intent: cutting "bright and lively" stones, from rough that reaches
50% saturation (white paper test limit), or darker.
3. How approaching or exceeding the critical angle, or other parameters, might
help accomplish this.
4. Known cuts that perform well in darker garnet rough.
Phil in Florida submitted this topic for the first of a new series of week

I am a faceter, I have been cutting stones for 11 years on and off.
I have been using a Graves Faceting Machine that I inherited from my
mother-in-law. I had no idea how to use this machine when I first got
it, I read the instruction book, but it was a whole new language. I
finally found a wonderful gent who took me under his wing and taught me
how to facet. I was hooked. I have taken several jewelry classes and I
have to say, I am far more comfortable with stones than with gold or
silver. I love to cut just about anything, though I haven't cut any
Hi Kecia, Welcome to the group. I think you will find many helpful gemcutters
here. Please feel free to share your cutting experiences with the list as well as
posting for help when needed.

I agree. Multiple (>2) internal reflections can
increase the path length through the stone. My point was
that it is the path length and not the reflections which
are causing the extinction of light.

Hi Dave, My original comment about number of bounces
was intended to be a reference to path length through the stone. I just
did not state it correctly.

Hello the List:
Reference Phil Stonebrook's inquiry as to whether Jim Perkins would care
to share the cutting instructions for the Derek cut.
Reference also two photographs of the Derek cut at
Jim notes that the cutting instructions can be found at
They can also be found in Volume 1 of the Greensboro Faceters Calendar and
in his Book 1 of faceting designs available from
I've cut several of Jim's designs and like them.

I have been working on some designs for garnets with strong colour
saturation. I have always preferred to cut a small amount of facets in
the pavilion as I prefer the results I had achieved that way.
If you would like to have a look at the designs please go to Dan =
Clayton's site http://gems.dnsart.com/modules/newbb/
You can mix and match pavilions and crowns with these designs. I will
cut Lighting Hope and will send a picture of the rough and the finished
I would like to thank Dan Clayton for all his valuable advise and help.
He kindly put the designs on his web site, making them available for
I hope some of you have a go at cutting one of the designs and let me
know what you think about the results.

TODAY'S FUNNY ~
Kids at the Wedding
At a friend's wedding, everything went smoothly until it
was time for the flower girl and her young escort to come
down the aisle.
The boy stopped at every pew, growling at the guests.
When asked afterward why he behaved so badly, he
explained, "I was just trying to be a good ring bear."
REFLECTIONS AND TIDBITS:
