D.C. jeweler to display rare pink Argyle diamonds
Later this week, Tiny Jewel Box will host a public exhibit of the world’s rarest pink diamonds as part of a partnership with Argyle diamond wholesaler L.J. West Diamonds.

Washington--Later this week, Tiny Jewel Box will host a public exhibit of the world’s rarest pink diamonds as part of a partnership with Argyle diamond wholesaler L.J. West Diamonds.
The exhibit, which will be displayed from Sept. 10 to 11 during normal store hours, will include 20 to 30 pieces of jewelry created with diamonds from Australia’s Argyle mine, valued at $25 million total.
Select pieces will be available for purchase, presenting a rare opportunity for collectors to purchase one-of-a-kind pink, fancy red and blue diamonds. The jewelry for sale is highlighted by a custom-made platinum necklace with fancy intense pink diamonds, priced at $6.1 million.
Tiny Jewel Box is collaborating with L.J. West Diamonds, a wholesale retailer of Argyle pink diamonds in the U.S.
The event marks the first time that this collection of Argyle diamonds will be on display in America. It previously was shown in London and Australia, and will move to the Asia World Expo in Hong Kong after the showing at Tiny Jewel Box.
The Argyle mine is the largest supplier of pink diamonds, providing more than 90 percent of global production. The mine has an estimated eight years left of production, making these diamonds even more exceptional, according to Tiny Jewel Box.
“Having spent our career handling some of the most unusual jewelry ever made, an opportunity to associate ourselves with some of the rarest colored diamonds ever exhibited is a unique opportunity for us and one we wanted to share with Washington D.C. Our tagline is ‘If It’s Not Special, It’s Not Here’ and these diamonds certainly fulfill that promise,” said Tiny Jewel Box Chairman Jim Rosenheim.
Editor's Note: This story was updated to reflect the new dates of the exhibit, which were changed to Sept. 10 and 11 due to the diamonds' travel schedule.
