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.

X-Cubes look great, can't wait to cut them! Always great service with Tom!

Great product with fast shipping

These look so cool when cut, thank you.

This material cuts so nicely
The colors are amazing

Material looks great
Will follow up with a picture of a finished gem from this wonderful material. First gemstones out of this fantastic material

Material looks fantastic will follow up with a picture of the gem when finished

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

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.

Great material, color is stunning

Cut this rough into a trillion. It’s spectacular!

Exactly as advertised. Great specimen, I will get a good amount of finished stones from.

Such a nice piece of lab grown corundum.

Great color, slight inclusions along seed plate, as to be expected with hydrothermal quartz.

Fast delivery, as described, this is a nice blocky piece of very clean synthetic rough. THANK YOU!!
