Natural Tanzanite Blue Sapphire Cushion Cut AAAA+ 12×12mm 10.50Ct Loose Gemstone For Jewelry Making

very nice stones, I like the size and color. picked the. up for my daughter to have gems

Well, the description is a bit confusing! Is it a Tanzanite? Is it a Sapphire? Not sure? It's beautiful! Nicely cut, no inclusions! Fast shipping!

Good quality. Nice color and looks expensive.

FYI, this is a *man-made* (lab created, also known as synthetic) sapphire. If this is a *NATURAL* sapphire... with this color and clarity, it would cost at least several hundreds of thousands of dollars, not $10, lol. Please be an informed consumer. Typically, natural *blue* sapphires do *not* glow under UV light (due to its iron content). This beautiful looking, man-made stone also does *not* glow. That said, I do have synthetic *blue* sapphires that glow under a UV light (Yellow, pink sapphires... natural and man-made... will glow under a UV light.) Compared to my other blue sapphires, this stone is slightly more purple. To the general public, it can be passed off as a tanzanite, imho. Awesome looking *man-made synthetic* stone, great price, quick shipping (from order to delivery to California took 5 days)...Highly recommended.

It’s blue and it appears to be a rock. I didn’t do any conductivity or light reflection tests. Shipping was quite fast from China to San Francisco California. The price was great! About $1 including shipping for the 1.2 cm square version I got. I would recommend it if you need a small blue gem that’s probably artificially manufactured sapphire. I wouldn’t trust that it’s Tanzanite… but maybe.

This is such a beautiful stone I had to buy two of Em. I love this and I've been showing it off, and people are amazed at how saturated the color is. And especially the red hue, it has in the side tone when looking at it through light, it is just gorgeous and the price is excellent and it looks awesome in my collection they both do
