The stars are bright and the stone is too
I order 2. 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
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
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.

GEMHUB 4.05 Cts, 6 Rays Red Star Ruby, Loose Gemstone
Star ruby is a prized variety of ruby, which is the red-color member of the corundum group. Ruby is closely related to sapphire in terms of molecular structure. . The quality of a red star ruby is determined by its color, cut, and clarity, and carat weight, which all add up to determine its value. The brightest and most valuable shade of red called blood-red, and commands a big premium over rubies of similar quality. This genuine Red Star Ruby passed all quality tests and has been fully certified, to assure that you have a real gemstone. I gave this ruby a four-star review due to small size and obvious flaws, but you can't expect anything else for less than $50!
