Afghanite yellow My best guess is that

My best guess is that the Zircon crystals were so tightly compacted during their growth that they didn't have any room to completely crystallize and actually formed as amorphous "blebs" under very high temperature and pressure

especially since it’s not a micro specimen and it’s very eye-catching

It has very smooth octahedral faces with a glistening almost "wet" luster and a beautiful color combination of a grape purple with pink tones swirling throughout

Betrandite is a fairly rare beryllium silicate

Afghanite yellow My best guess is thatThis stone is one of the best examples of GEM FACET GRADE Afghanite that we've had to offer. It has a "Cushion" cut with nearly eye clean clarity but perhaps the most intriguing part is that it features a strong glowing sapphire blue color (comparable to Hauyne) that is not often associated with Afghanite. This piece, along with several others from the recent mining efforts, has been analyzed and confirmed as Afghanite by several laboratories around
