Compiled by Sharon Elaine Thompson

The Gemstone Price Index is limited to gem rough available to amateurs and semi-professional cutters at shows, on the Internet, and from wholesalers. For this reason, it does not include rough such as emeralds, ruby, exceptional quality blue sapphire, or imperial topaz -- materials that are not readily available except to professionals.

There are a growing number of online merchants buying close to the mines, and their prices may be very good. However, when buying from this sources for the first time, always check payment options, guarantees, and return policies. Overseas shipping, insurance, and credit card charges may not be refundable; you may have a very short time in which to examine the material; and you'll have to pay return shipping. Remember that photos and grading terminology may not be accurate. If you decide to buy, always make a small purchase first to verify quality of material and veracity of seller. As always, caveat emptor.

to end an argument between my dad & myself about the GPI what exactly do you mean by

1. cut, commercial   1-3 ctw

2. cut, gem                 1-3 ctw

3. rough, commercial     ctw-grams

4. rough, gem                   etc...

 

i take the cut, commercial to mean  a faceted stone of comercial grade  such as poorer cut, clarity, polish etc..

and cut,gem to mean a faceted stone of gem quality such as   AAAA+++ no inclusions, fractures and a perfect cut and polish job

while his deffinitions differ as to what you mean by that and on one particular Item of nice material we have a $48,000 difference as to how much we think its worth ( I am on the conservative side thinking $300-$600)

as it was your list that started the arguement I would appreciate your help in settling it,  so I can eat crow cooked by an expensive chef or prove to him what it means from a source that he will listen to.

 

urgently waiting your help scottii69@yahoo.com

Here is a vidio that will explain some of it.

Mainly the angles of the cut and meet points of the facets, flaws in the matl are a couple of things.

Gem rough is usually flawless in most matl. but not all, some matls just have more flaws then others.

Hope this helps some.
