6 x 4 mm Oval Cut Lab Created Ruby lot of 2 stones These rubies are grown in a laboratory to produce eye clean gems, the material is the same mineral(corundum) as natural rubies just the process that takes millions of years in the earths crust is shortened to weeks in the laboratory. These gems have the same hardness, refractive index and beauty as the naturally formed stone and are indistinguishable from natural stones without using specialist scientific apparatus. No additional shipping cost if buying more than one lot. If wishing to combine with any of my other items please contact me for a combined invoice before paying.
