- Size: 4.9 x 3.4 x 2.9 cm.
- From the exciting recent find in Mali, this specimen represents the very TOP- with rare MATRIX association, and high luster on the large crystals. From a knowledgeable collector: “Ugrandites are a rare intermediate between andradite and grossular. In other words, Mali Garnet. This series leans toward the andradite end, in my opinion. What seems to be unique is the very strong presence of chromium. I’m surprised that the body color isn’t more green. I imagine that is due to the presence of color killing iron. I thought this might interest you.” Well, that is more than what we knew – we had heard that they were under study to see if they were demantoid var. topazolite garnet. Anyway, an exceptional specimen from this find. The crystals measure to 2.2 cm across - and again, matrix specimens are exceedingly rare.
