Phillips, in association with Canadamark, recently showed off what’s being described as the largest diamond ever mined in North America.
The yellow diamond has yet to be named, though it’s currently nicknamed “552” for its weight in carats.
It was discovered at the Diavik Mine in Canada last October.
The diamond was on display at the Phillips galleries in New York from Jan. 31 through Feb. 3.
“As of yet, the stone must be thoroughly examined and cut before being graded and sold,” according to a press release from Phillips.

552 is ranked 25th on the list of the world’s largest rough diamonds, just ahead of the Lesotho’s Letseng Star, weighing 550 carats.
“It has been determined that the age of this diamond is approximately 3.1 billion years old, making it older than a vast majority of diamonds unearthed in this region of Canada,” according to Phillips.
Four Decades of Excellence: How Wilkerson Transformed a Jeweler's Retirement into Celebration
After 45 years serving the Milwaukee community, Treiber & Straub Jewelers owner Michael Straub faced a significant life transition. At 75, the veteran jeweler made a personal decision many business owners understand: "I think it's time. I want to enjoy my wife with my grandchildren for the next 10, 15 years."
Wilkerson's expertise transformed this major business transition into an extraordinary success. Their comprehensive approach to managing the going-out-of-business sale created unprecedented customer response—with lines forming outside the store and limits on how many shoppers could enter at once due to fire safety regulations.
The results exceeded all expectations. "Wilkerson did a phenomenal job," Straub enthuses. "They were there for you through the whole thing, helped you with promoting it, helping you on day-to-day business. I can't speak enough for how well they did." The partnership didn't just facilitate a business closing; it created a celebratory finale to decades of service while allowing Straub to confidently step into his well-earned retirement.
