Flawless Round and Marquise-Cut Diamonds Lead Upcoming Brokers Investment Auction

Diamond experts agree that one of the most niche cut diamonds out there is a marquise cut. This summer, Bid Global International Auctioneers LLC is offering a 10.18-carat, marquise cut diamond appraised at $4,581,000 by the Accredited Gemological Institute (AGI). It is a type IIa flawless diamond with D color and is graded by the Gemological Institute of America (GIA). Its length and breadth ratio also looks proportionate. Another featured diamond is 12.22-carat round-cut diamond. It is also a type IIa flawless diamond with D color that comes with a GIA laser inscription.

Notable among colored diamonds is a 3.02-carat natural fancy intense yellow diamond. This oval-cut diamond has VVS1 clarity and F color. It also comes with a GIA laser inscription and has an appraised value of $244,600. Other than single loose diamonds, the Brokers Investment Auction offers a 4.02-carat diamond pair. They are both cushion-cut, GIA-graded diamonds. Both diamonds weigh exactly 2.01 carats and have the same I color, which is rare to find in a pair. But the slight difference is seen in clarity. While one has VS1 clarity, the other has VS2. There are more than 300 loose diamonds and gemstones available in the auction. Find the listed items and more online auctions on Bidsquare.
