About the Item

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. You'll make the statement with this ring that features a GIA certified 8.70 carat elongated cushion cut. Its gem source is Sri Lanka; its color is royal blue with hints of cornflower blue. It measures 14.39 X 10.70mm and has excellent transparency and luster. 20 scintillating round brilliant cut diamonds surround this blue sapphire in a glittering halo cluster totaling 1.24 carats all in brightly polished 18 K white gold. This gem has presence.

This stunning cluster ring is supplied with a sapphire report card and certificate supplied by the Gemmological Certification Services, London**, in addition to a diamond grading report card for the supporting diamonds. NOTES: * Ceylon sapphires (mined only in Sri Lanka) are known for their unique color, ranging from very pale blue to vibrant almost electric blue. The colors noted within Ceylon sapphires occur naturally and do not tend to be heat treated, the most sought after known as the cornflower blue. ** This documentation accredits the blue sapphire originating in Sri Lanka (Ceylon) and certifies that the gemstone shows no indications of heating; non-heated sapphires are a scarcity.
