4 42ct Tanzanite Emerald cut gemstone 12.01 by 7.24 by 5.29mm Certified VVS grade Certified Tanzanite gemstone 4.42ct from Arusha Tanzania. This is sensational - a bright purple blue color. Good cut and very good clarity. Emerald cut gems are notoriously difficult to cut in terms saturation and quality of the cut - and even more difficult to photograph. Now this gem is a little windowed as is often the case with this kind of cut and the saturation is not perfect and is actually enhanced by the cut - but it is still a beautiful gem. In fact we have not helped matters by photographing on a mirror as it enhances the windowed effect. So please bear this in mind. It is a gorgeous gemstone. The certificate for the gemstone will be included in the sale and it was certified by a friend of ours who is a Fellow of the Gemmological Association of Great Britain.

Please consider the level of magnification of this gem which is way beyond the 10 times magnification used for grading - we use a Nikon camera and top of the range Macro lens and a light tent. So some of the flaws you may see in the photo you will not even see with a magnifier.

Why are users outbidding themselves?

When a bid is placed, this is the maximum amount a user is willing to bid for the product. Our system will then automatically bid on that users behalf, incrementally increasing the bid to maintain their position as the highest bidder, up to the specified maximum.

When there is an icon indicating 'Auto Bid,' it means our system is actively placing bids for the user based on their maximum bid. This may appear as if users are outbidding themselves, but it's simply a result of the system updating the bid to reflect the users maximum limit.

Audit

The Gemstone Sheriff program allows our members to request an audit on any product, which is completed by an independent Gemologist who assesses the accuracy of the item description and pictures.
