“Gem Guide” iOS app is the reference section of iGemology. It was designed to supplement "Gems Carat" users for their gem reference access. Gem Guide also can be used as a stand alone application for users who do not require gem weight estimating feature found in "Gems Carat" or "iGemology".

Gem Guide provides an efficient gem cross referencing tool for all “Gem Trade Professionals and Enthusiasts”. As a Graduate Gemologist (GIA), I am eager to share this source of knowledge, which I have designed and programmed.

“Gem Guide” is not yet a substitute for a desktop application, due to inherent & present limitations of any mobile devices’ resources, i.e. Memory and Screen Size.

As a full featured Gem Reference app with spectrum data analysis (Light Absorption Properties), Gem Guide assist trade professionals, jewelers & gemologist in gem evaluation & identification. It is also a reliable source of knowledge for sales staff, gemological students or any gem buff.

“Gem Guide” also provides quick reference on size to weight co-relation of calibrated Diamonds and Colored Stones, both in melees, full sizes and baguettes cuts.

Common in “iGemology” suite of applications are direct access’ to Diamond Grading Lab Report and Fine Metal Market for Diamond Report verifications. Gem Guide also conveniently provides access to Jewelry Crime Related Reports with direct reporting a crime capability to Jewelers Security Alliance (JSA).

President of Isometric
I am a previous professor of the Gemological Institute of America. I recently downloaded this software and I am glad I did. Obviously! These people are making a difference for those who do jewelry appraisals and a great tool for all who need help in grading. Good work. I hope to see you expend even further.
Great App
This a great app. Im new to this topic so its a great resource for me. I think a section on test equipment would be a nice add for the future. love it so far though.
