About Corundum Gemstones

Corundum itself is not a very rare mineral, but transparent gem-quality corundum is extremely rare. Most corundum is opaque to translucent and heavily included, suitable only for industrial use, including the production of abrasives used for sandpaper and machining of metal, plastics and wood, and as of recently, has become very important in the making of mobile phone components. The name 'corundum' comes from the Sanskrit word 'kuruvindam', meaning "ruby sapphire", which are the two distinct members of the corundum family.

Ruby is red corundum, while all other colors are referred to as sapphire. Blue sapphire and red ruby make up 2 of the 'four precious gems', which also includes green emerald and diamond. While there is no definitive distinction between red ruby and sapphire; in many cases, a near-red sapphire may be classed as an inferior color grade ruby. Thus, it is usually more common of practice to trade near-red sapphires as 'high-grade' fancy sapphire, rather than as 'low-grade' ruby. The corundum family includes variations of ruby and sapphire, including color change sapphire, star sapphire and star ruby. Ruby is also found in mixed gems such as ruby-zoisite and ruby-in-fuchsite.

I like that they have lots of gemstones, I would like to see a mixed lot. It would be nice if I could get a mixed lot of gemstones.

Site was recommended to me by my gemology professor. Based on what I’ve seen gemselect offers good quality stones for a large range of prices

Ive been shopping here many times before, so navigating around was easy. I am accustomed to the quality of the items and that's the main reason I come here. When I need non heated stones I know I can count on GemSelect being authentic. I trust them because I double check their quality. And never had problems with them. And yes I do recommend shopping there to some of my clients who are "less knowledgable" of industry. GemSelect is so user friendly they're great for beginner gem shoppers!

Well fell in love with the site right away ordered two many items I knew I would return a few. Decided I wanted to invest in a sapphire emerald or ruby after more research. The diamonds that I received we just stuck together just ordered one more I will have 10 in all diamonds two yellow six white. I'm so very happy I didn't know what I was going to keep and definitely diamonds were winner.
