Malaya Garnet

20/12/09 20:56 Filed in: Latest Cut Gems
One new stone tonight. This one is a Malaya Garnet from Tanzania. The color range of Malaya Garnets is pretty broad, and this one is one on the more orange side. Just under 2 cts.

Christmas Gift

Here's a little free Christmas gift to go along with the Christmas Sale

I have been working on this program in my spare time, to do some geological calculations. The program has two simple screens to help with some measurements and calculations. The first screen helps with a Specific Gravity calculation, and shows you the accuracy you can expect from your calculation based on the accuracy of your scale.

The next calculation is used with a refractometer to determine the optical character and sign of your stone. This information is very critical in gemstone identification, but is often overlooked since it's a bit complicated to work out. This program makes it simple. Below are a few screen shots form the Apple version. The program is available to run on both Apple Mac's and Windows machines.

For my fellow cutter who are running a Mac and using Numbers instead of Excel, there is also a spreadsheet download to do Tangent Ratio Calculations for Numbers on the download page.

Every stone marked down until Christmas Eve

One new stone tonight, in a very Christmassy color. This one is a Tsavorite Garnet from Tanzania, and just perfect color and tone. The picture isn't close to the intense chrome green color of this stone. Green never photographs well with my camera. The stone is 2.56 cts.
