A Rare Suite of Rubies Has Arrived in Las Vegas
The “Royal Ruby” Collection is a quintet of untreated rubies curated by collector Jack Abraham.

The collection belongs to Jack Abraham, founder of New York-based jewelry company Jack Abraham-The Precious Collection, who acquired the quintet over the course of four decades.
Combined, the rubies weigh more than 50 carats.
The group consists of: a 17.88-carat ruby from Madagascar, a 9.08-carat Thai ruby, a 7.11-carat ruby from Myanmar (formerly Burma), a 10.99-carat ruby from Mozambique, and an 8.47-carat ruby from Tajikistan.
Each is set into a ring.
Abraham began collecting the stones individually about 50 years ago, starting with a 5.79-carat no-heat ruby from Thailand that he bought in 1979. It was the second ruby he’d bought under his company name.
The suite is meant to be one-of-a-kind collection showcasing natural rubies’ range of physical attributes, so it has been upgraded over time.
“Every time I find a stone that is bigger and/or better, I replace it,” Abraham said.
Around 20 years ago, he sourced the 9.08-carat Thai ruby, which is currently in the suite (and the oldest one in the group), and put the 5.79-carat Thai ruby on the market.
It sold two years ago.
The “Royal Ruby” collection made its debut at the 2024 reopening of the Yale Peabody Museum in New Haven, Connecticut, following an upgrade of the Minerals, Earth, and Space halls, part of a museum-wide renovation.
American Gemological Laboratories founder C.R. “Cap” Beesley, whom Yale tapped in 2016 to chair the advisory board overseeing the expansion, reached out to Abraham about putting the multi-million-dollar collection on display.
In a Roskin Gem News Report article about the reopening, Beesley said Abraham was among the museum’s “most prolific and consistent supporters in the gem and jewelry sector.”
The suite was on view but only for the first few months before and after the museum’s grand re-opening.
Abraham pulled the collection in November to show the rubies at the 2025 Tucson gem shows, where he said the suite received “a heck of a response!”
He’s currently exhibiting at JCK Luxury.
By noon on Wednesday, which is an invitation-only day for buyers, Abraham told National Jeweler he had interested buyers for three of the stones.
However, he’d prefer to see the rare suite kept together, ideally displayed in a museum.
“The [collection exhibits] nuances of colors and origins, plus the stones have not been enhanced in any way,” Abraham said.
“[It deserves] to be shown some place where [people] can see the differences in colors, the secondary and primary hues, and the depths of the colors—the ‘positive’ colors that make it a good red and the ‘negative’ colors that make them a bit less red.”
