My wife and I recently came across a ring left to her by her mother. Her mom bought it almost 20 years ago as an orange diamond and tested with a thermal probe it immediately tests positive for diamond and the Refractive Index as tested by a Graduate Gemologist showed it as OTL and a diamond. The GG then turned around and said she didn't think it was a diamond but rather a Spesspartite Garnet. She said that sometimes they will test positive. Well I had never seen or heard of this before so I'm dubious about her decision considering she was attempting to purchase items from me. As an example she offered $900 for a .90 color G VS1 round diamond and I thought that was very low.
Any thoughts would be appreciated.
