Excellent Loose Diamond - Natural Diamond - 1.32 Carats - Certificate - BIN / BO

This listing is for the diamond only. The diamond was recently removed from its setting, cleaned and safely packed away. It is a 1.32 carat natural diamond, marquise cut, E, SI2, and comes with the original EGL International certificate and I can include the original appraisal from when I purchased it with an appraised value of the full ring at over $10,000 US. Buy It Now is available but I will consider offers and I will ship internationally but the listing settings are off due to my location so I set a flat shipping rate of $50 US and if it ends up being more I will cover it from the sale. Questions — please ask. No returns. The sale is final.

Pre-ownedBuy It NowBest Offer

NATURAL COLORED DIAMOND / .72ct Trapezoid Cut / ORANGY CHAMPAGNE / 5x6.5mm, CHIP

It would make a great center stone for a pendant or ring, especially a man’s ring. The color is a natural, orange-brown champagne and is quite eye catching. I would rate the clarity as slightly included SI1 but there is a small chip on the underside that doesn’t show when looking at the stone from the top (see photo).
