The Esperanza diamond is the most valuable diamond ever discovered in the USA, found by Brooke Oskarson at The Crater of Diamonds State Park in Arkansas. Brooke enlisted the help of a number of American Gem Society members to collaborate and turn her find into something even more remarkable, ensuring the unique provenance of such a rare American diamond.

Unearthing Esperanza at The Crater of Diamonds State Park, Arkansas

The Crater of Diamonds State Park in Arkansas is the only public place in the world where, for a fee, you can dig for diamonds and keep what you find. The Esperanza diamond was found there in June 2015 by Brooke Oskarson, of Colorado. At 8.52 carats in its rough form, Esperanza is the fifth largest diamond ever found at the Park. Oskarson named the diamond Esperanza after her niece, and also the Spanish word for hope.

A live cutting event held in Little Rock, Arkansas

Stanley Jewelers Gemologist is located in Little Rock, Arkansas, two hours away from the Crater of Diamonds State Park. When Laura Stanley heard about Esperanza, she knew The American Gem Society (AGS), of which Stanley Jewelers is a member, could help. Oskarson had already taken the Esperanza diamond to Neil Beaty, gemologist and AGS member, who then referred her on to Stanley. So began the involvement of more AGS members in a bid to ensure the unique provenance of such a rare American diamond.

AGS member and master diamond cutter Mike Botha of Embee Diamonds was given the task of cutting Esperanza, at a live cutting event at Stanley Jewelers. Botha created a new type of cut - the triolette - for Esperanza, which he says was intended as “a unique design for a unique diamond that shows off the color and transparency from every direction while preserving as much weight as possible”. Botha spent 180 hours cutting and finishing the diamond into a 4.605 carat diamond with 147 facets.

Sending Esperanza to the lab for grading

The cut Esperanza diamond was then sent to the American Gem Society Laboratory to be officially graded. The results? A Type IIa, internally flawless diamond of D colour — basically the purest diamond you can get, and the reason why Esperanza is the most valuable diamond ever discovered in the USA.

Designing a pendant for Esperanza

The Esperanza stakeholders asked Inspired Jewellery (also an AGS member), to design a piece of fine jewellery as the setting for the Esperanza diamond.

Ian Douglas, Creative Director of Inspired, set about designing a pendant for Esperanza. Without being able to see the diamond first hand, all Douglas had to guide him was a 3D model. From sketch, to CAD renders, and finally a 3D printed wax model, his design was ready.

“Our ethos is that the diamond should always be integral to the design, not an afterthought. In the case of Esperanza, it couldn’t be any other way. When I design jewellery, I imagine a diamond, floating, unconstrained, revealing its beauty in its entirety. I then design works of art to connect that diamond to the wearer”.

Douglas’ design floats the Esperanza diamond above the setting, as if it is suspended mid-air. The diamond is only secured at each pointed end. Flowing from these ends are fluid shapes and lines of platinum which form the base of the pendant, echoing the shape of Esperanza. They are designed to look like tapering droplets of water. Smaller Canadian diamonds are set into the platinum.

The pendant was then crafted by Byard. F. Brogan, a jewellery manufacturer in Philadelphia.
