Weight (carats) 4.07 carats
Certified Gemstone
No Treatment

Freshly faceted cobalt spinel. 4.07 carats. Looks loupe clean. VS to VVS quality. No abraded edges on the facet edges. Better than eye clean stone.  Please look at the stone in the video closely.   You can see the exceptional cutting on this stone.  As it is rotated please notice the beautiful pavilion which is the bottom part of the stone.   It is nicely pointed which is why it has a high degree of internal reflection as opposed to a stone with a shallow rounded bottom and a huge resultant window.  This is why this is more of a true gemstone because of the beautiful cutting and the symmetry.   

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.
