This piece comes directly from the vault of Atlantic Diamond Company—a family-run fine jewelry house with nearly 50 years of history serving elite collectors, retailers, and dealers across the country. As the founder shifts focus to new ventures, he’s releasing a final selection of investment-grade gemstone and diamond pieces—offered exclusively to 1stDibs buyers at exceptional, below-market prices. This is not a liquidation or sale—it’s a one-time opportunity to acquire legacy-level jewelry at true insider value. Each piece is final; once sold, it will not be restocked. This ring holds a vibrant green tsavorite garnet from Tanzania. The weight of this tsavorite is 3.54 carats. Its luster and transparency are excellent. 84 sparkling mixed cut diamonds surround this tsavorite in a glittering halo cluster and down the sides of the band totaling 0.86 carats.
