    Not As Described
  

*by K***S on Reviewed in the United States on October 21, 2018*

The stones are listed as Created (synthetic) Sapphires. They are NOT. They're selling synthetic Blue Spinel but trying to pass it off as Synethic Sapphire (Corundum). Not the same thing by any measure.

### ⭐⭐⭐⭐⭐ 







  
  
    Beautiful Rubies. Very Pleased!
  

*by B***S on Reviewed in the United States on January 27, 2018*

These are just as advertised! Beautiful pink-red created rubies. And exactly 200 by my count! Prompt delivery and unbeatable pricing. Very pleased with this Seller!

### ⭐⭐⭐⭐⭐ 







  
  
    These red stones are true synthetic corundum-based rubies--not spinels.
  

*by R***G on Reviewed in the United States on August 27, 2020*

Correctly labeled by the manufacturer as Red Corundum, these are beautiful gems display the full fire and flash you would expect from a fine corundum synthetic gem--they are NOT spinels. Quite a good value, I will buy more, but I would also buy them in 12mm round if ever made available in that larger size.PLEASE NOTE: I also purchased the blue stones in 10mm, and this color--as well as the green stones--are NOT corundum-based--they are spinels. Although these spinels are almost equal to corundum-based synthetics in fire and flash, I find the blue stones a bit too dark for my tastes, and I would recommend a lighter color profile, just for the blue color.
