Large and flawless lumogarnet

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.

Very fine color more on the green side. It is hard to capture faithfully, but that material will cut me few very beautiful stones.

Padparadscha TGT Pulled Sapphire - Grade A - Faceting Rough
Nicolas B.
Padparadscha TGT Pulled Sapphire - Grade A - Faceting Rough

Very clean material with strong pleochroism. Peachy pink with strong orange reflexions, i am not familiar with natural pad saphires but am a sucker for this one for sure !
I am attaching a picture but reminding you that its hard to capture its true color, it looks better in person.

As for the purchasing process, very smooth, quickly sent and faithful to the pictures. I love the millimeter paper pictures which greatly help to appreciate the size of the sample. Hope there will be more of that material to purchase in the future.
