This 3.25 ct gem is a more tonal shift than color change. I’ve seen so many now that some just change the tone from a blue to a violet blue and not a lot of change compared to some others. This one looks nicer under the lights and goes deeper blue violet and more a inbetween blue outside light. The photo’s were all taken in outside light which doesn’t show off the more richer color in my mind. I’ll try to add a video later on. The stone is not quite eye clean as I see a speck only at certain angles through the stone that looks like a line of fog under illumination and magnification at 15x power. Nothing to be alarmed about. The smart investor will snatch this up quickly as I greatly reduced the price of the stone because of this and put the stone up for only a one day bid to avoid a bidding war. It is a stunning gem and I hope I caught that in the photo’s. I am practicing each day to get better photo’s. I don’t have a certification for this one but I think it has cobalt.
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.
