The Faceter’s Tale
First of all I should probably explain why this is a faceter’s tale and not a cutter’s tale. A gem cutter is an artisan usually working as fast as he can because time is money and gem setters will always becutting corners off emeralds and asking the cutter to put them back again! A faceter is an artisan with all the time in the world trying to produce an article of beauty,

Letter to the Editor:
I'm a self taught faceter as I assume are the majority of the UKFCG guild members, however, during the past 4 years I've tried to hone my techniques with very rewarding results - yes I've had problems and made mistakes, some trivial others major, still do have these occasionally.
A big thank you to Keith Ardron for the following:

Hints on photographing gems
Cheap high-resolution digital cameras are often equipped with a built-in lens capable of focusing very close, so it is now easy to take photographs of gems. However, it is not at all easy to get perfect pictures.

EMERALD CUTS FOR VERY LOW REFRACTIVE INDEX MATERIALS
The Emerald cut was designed to show the rich colour of emerald whilst having cut corners so that the brittle stones would not get damaged. As I investigated in an earlier article (Stonechat 72), for stones of refractive index below beryl (about 1.57) this style of cut is limited in brightness. This is a shame as the long facets down the side of the stone show colour very well and the general outline of the cut can be very attractive.

FITTING STOP LAMPS TO GRAVES MK IV AND ULTRA-TEC MACHINES
Faceters who use ‘hard stop’ machines will know that it is easy to overcut if a slightly raised finger pressure is applied to the stone after the stop block has been contacted. This is especially true on
machines which are slightly wanting in rigidity.

SHARING THE SECRETS.
Picture the scene. In my hand is a large piece of dream rough, the sort that must have cut those fancy bits in the museum. This is going to be the definitive cut. In my minds eye I can see the ideal shape which will fit in between all those nasty looking cracks and blemishes. The angles will fit perfectly. This will be the big one,

DOP IT SQUARE!
New-comers to faceting will find that the literature is full of advice on the dopping procedures. Some of these are unnecessarily complicated and advocate a range of heat lamps, irons, spirit stoves, hotplates, painting the stone with shellac, light bulbs etc. all geared up to getting the stone warm to stick to the dop. Very few address the basic requirement of getting the stone on the dop square.

I'd rather not be telling about this... in fact, I wish it had never happened to be written about. But, in the hope of averting future pain and possible tragedy for other FACETS readers, I tell this tale of woe. Pin wearing a rather uncomfortable back brace these days - and have been for the past seven weeks. All because of neglected safety precautions.
