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 have used this site for sseveral years now. All has been great. I started collection gems from GemSelect for years and wanted to collect at least one of most stones. I loved Safers because the mols is a 9 + and they come in every color. This is the best place to buy gems for the assortment and price. Great place to learn about gems too. Sometimes the shipping is a little on the long side. But I would give them a 9.9 out of 10 !!

Everthing about researching and ordering from Gemselect was easy and uncomplicated. In the past I had payment problems, but your customer rep, Thomas, helped me get everything right. I will continue using Gemselet in the future for these reasons.

I am of the opinion that the company gem select cares about the product beautiful gems it sells and the cost of the gem I purchased was small i was treated as if it cost a lot of money and product was described in detail and i felt good about the little stones i had ordered.
