Natural stars are so expensive to buy here and the stars are usually not very obvious. My husband ground one for me years ago and it was stolen. These are beautiful replacements. The stars are bright. And they arrived 2 weeks ahead. Review: Excellent lab star ruby - Seriously gorgeous translucent red corundum with an excellent asterism. A nice change and more fitting for a men’s ring compared to all the opaque pink lab star rubies out there.

Natural stars are so expensive to buy here and the stars are usually not very obvious. My husband ground one for me years ago and it was stolen. These are beautiful replacements. The stars are bright. And they arrived 2 weeks ahead. ### ⭐⭐⭐⭐⭐ Excellent lab star ruby *by P***S on June 27, 2023* Seriously gorgeous translucent red corundum with an excellent asterism. A nice change and more fitting for a men’s ring compared to all the opaque pink lab star rubies out there. The cab is wonderfully large too around 12x10 with a very nice dome height (can’t stand it when oval & round cabs are cut so low & flat) ### ⭐ Not as described, beware *by S***R on December 19, 2025* Could not get the starter show up at all even under really bright light not as described. It just looks like a Red stone. I would’ve bought a ruby if that’s what I wanted. Not as described, I guess they don’t have a quality control. ## Frequently Bought Together - GEMHUB Gemstone Necklace 4.00-8.65 Carat.
