Beautiful blue tanzanite. Close to loupe clean. VVS quality. Extremely clean looking when viewing with jewelers loupe. Nearly 10 x internally flawless it looks to be upon examination. Very reflective stone. No apparent window which is often seen in tanzanite cut stones.
Certificate is online verifiable using the square through the photo function of your camera. It automatically brings up the certificate through the website.
When heated to 750 to 900 F or 400 to 500 C the brownish tints vanish and the tint of blue deepens.
Before heating the stones are trichroic which means three different colors depending on the direction you are looking at the stone. After heating the stones become dichroic which is two different colors. The best of the best is royal blue when viewing down at the face of the stone. Some tanzanites show royal blue from all directions. I try to take tweezer videos and photos but I'm scared to drop the stone and I take my shots outside. This one kept twisting in the tweezers and I didn't want to chance dropping it. I'm not the best at taking videos or photos.
This stone is masterfully cut without window. Full reflection.

为什么用户出价高于自己?
当有人出价时,这是某人愿意为产品出价的最高金额。然后我们的系统将自动代表竞标者出价,逐步提高出价直至最高价,以保持其最高出价者的地位。
当出现“自动出价”图标时,表示我们的系统正在根据出价者的最高出价为其出价。这可能看起来像是出价者在出价高于自己,但这只是系统更新出价以反映出价者的最高限额的结果。
