Beautiful looking blue spinel.  Better than eye clean.  If you check both the magnified photos and video you will note even under magnification the stone looks free from inclusions.  I had this listed as certified cobalt in my files but cannot find the certification now so I’m not listing it as certified although I know what the stone is as I have lots of experience with spinel and cobalt spinel.

I think the photo’s show the stone well as does the video.  I picked this one up in Beruwala Sri Lanka.  

Think this is cobalt spinel but I have no certification.   I checked with chelsea filter and it goes reddish like cobalt spinel and the stone shows the blue to violet color change same as cobalt spinels do.  

Sri Lankan spinel gemstone.  I try to price my stones below other sellers and try to make sure all customers are getting a true gemstone at a bargain price.   There is an article on this site about blue spinel titled “The rarest of them all”.  It is located in the learn section under Additional Gemstone Information.   Spinel is rarely treated or heated as it naturally comes without many inclusions and heating does nothing to increase the beauty of the stones.   Spinel is rapidly becoming more popular.  I’ve heard many gem affectionados state it was their favourite gemstone.  It was once thought to be sapphire or ruby depending upon the color.   The imperial crown housed in the tower of London has a large red spinel which was once thought to be a red ruby.  It is named the Black Prince’s Ruby and has a recorded history dating back to 1366 AD. Cobalt is the main colorant in blue spinels and are especially rare.  For me I prefer them over sapphires.  The better price, less inclusions and lower cost make it the better value.  It is also a hardness of 8 which is only slightly under sapphire so is good for everyday wearing.

I like to post my stones at much reduced prices over other sellers.  Check it out and see for yourself.  I was trained by my wife to understand my money is made when I bargain with suppliers not when I sell the stone to my customers.   So this is where I get to sell at reduced prices for the best quality stones.  I only pick the best quality.  No cracks or obvious inclusions.   All my stones are eye clean or better.
