Gemology Tools Professional is Windows Software for researching data of gemstones. The program was started by me, Bill Wise in 1993. I started it because there wasn’t a program out there for gemologists. Surprisingly, there still isn’t a stand-alone program over 30 years later (that I know of).
* Work arounds for Mac include installing Parallels (not free) or using Wine (free). Wine does not require the purchase of a copy of Windows. We’ve even had customers pick up a very cheap used Windows machine because even a 25 year old machine will run GT Pro!
