Large and flawless lumogarnet. I look forward to cutting this stone in the future, it is ideal for a large single die, and if I am careful about how I design it, I will have plenty of extra material for smaller cuts.
Got the material as it is luridly fluorescent.
Looks good, anxiously waiting to Haven IT faceted
I acquired some LuAG from Tom's Box of Rocks. Fascinating material with interesting properties and excellent service from Tom.
I am completely smitten with this material and these are perfectly shaped chunks for cutting! Can't wait to make some stones with them!
