“Deep Red” is really orange!

CZ was labeled “dark red” but looks more red-orange on the surface and is a strong orange with light passing through! I got this for a very specific project so it will not work for me, but still wonderful quality and excited to use it for other cuts!

Sky Blue w/ Green Fire Aurora Opal - 80% Resin - Lab Created Faceting Rough
Florian Lechner
Just cut my first my first piece from this

Just cut my first my first piece from this.
Getting a rough shape was easy enough with conventional tools (saws, sanding wheel). Refining it freehand on a vevor was also really quick. Polished it with zona papers and it came out beautifully.

These work great

These work great. They’re thick enough to handle the weight of my Batt and sintered laps. I’m very happy with the custom labeling as well.

Terrific hydrothermal emerald rough

Shipped promptly. This rough hydrothermal emerald is darker than typical Colombian color, a nice thickness >10 mm and super clean with potential for a nice “jardin” once cut. Thanks again to the team!

Thanks for being so accommodating and patient with me and my Alexandrite customer

Thanks for being so accommodating and patient with me and my Alexandrite customer.
I have the rough now and it is cut exactly like I requested. I will follow up with a gemstone photo when I have it cut.
I would like to take advantage of the 25% discount with another piece of rough exactly the Same as this order. However I am leaving Arizona and my machine for South Dakota summer time. Won’t be back to Arizona until October. Hope you could give me the discount then.
Thanks for the beginning of a nice friendship.

#1.25-#9 Ruby Sample Set Lab Created Corundum Sapphire Faceting Rough
James Pool
Wow the size is much larger than I expected!

Wow the size is much larger than I expected! It will be a while before I start to facet this. I’ll have to get a small trim saw for some of this as I will not want to cut every one as a single very large stone. They all have great clarity and color.

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.
