Description from the seller
Magnificent 4.046 ct Natural Cushion Cut Teal Sapphire – Bellerophon Certified – Completely Unheated
Presenting a premier investment-grade collector’s gemstone: an extraordinary 4.046 Carat Natural Bi-Color Teal Sapphire, officially certified by the renowned Bellerophon Gemlab (Place Vendôme, Paris).
This substantial gemstone is completely unique, possessing a rich and moody Deep Greenish Blue body that beautifully opens up to display a brilliant, glowing golden-yellow eye right at its crystalline core when exposed to light.
Expertly faceted into an elegant cushion cut with ideal 8.76 x 8.70 mm facial proportions, the stone exhibits strong fire, structural brilliance, and excellent face-up transparency.
Most importantly, this sapphire has No Indications of Heating, preserving its color exactly as nature created it over millions of years within basaltic mineral deposits. Stones of this scale (exceeding the critical 4-carat mark) that remain completely untreated are increasingly difficult to source on the global market.
A breathtaking centerpiece choice for an exclusive, custom-designed high-jewelry piece or a stellar addition to an estate gem collection.

It is your responsibility to review all of the information provided about an object, including the condition and description, before placing an order. Sellers are responsible for the information, pictures and description provided, including the quality, quantity and nature of the jewelry supplied. A small imperfection that cannot be seen in the photo but is included in the description is not a non-conformity.

A Lab Report contains only the characteristics of an article described after it has been graded, tested, examined, and analyzed using the techniques and equipment used at the time of the examination from that specific Lab. The results of any other examination performed on the article may differ depending when, how, by whom and with which grading standard the article is examined. In addition, any changes and improvements in techniques and equipment that may have occurred which may enable the examiner to detect, among other things, the use of processes for altering the characteristics of an article which use was previously undetectable, does not automatically mean the object does not conform to its description.
