The Geneva Pink: Phillips Unveils a 6.95-Carat Fancy Vivid Purplish Pink Diamond
On 10 November 2025 at 3 p.m. CET, Phillips will present one of the most anticipated gems of the season at The Geneva Jewels Auction: V: Lot 416, an Exceptional Fancy Vivid Purplish Pink Diamond Ring. This remarkable jewel, set with a cushion modified brilliant-cut diamond weighing 6.95 carats, represents the pinnacle of natural colour rarity and gemmological excellence. Flanked by two triangular diamonds and mounted in an elegant ring of size 52, the stone commands immediate attention for both its saturated hue and its impeccable clarity.
Accompanied by GIA report no. 5221485529, the diamond has been graded Fancy Vivid Purplish Pink, Natural Colour, and VVS2 Clarity, along with a Type IIa classification letter and a GIA Monograph—a distinction reserved only for stones of extraordinary importance. Type IIa diamonds are among the purest found in nature, containing little or no nitrogen within their crystal lattice. Representing less than 2% of all gem-quality diamonds, they are celebrated for their transparency and soft, homogeneous glow.
The pink hue of such diamonds is a geological enigma. Unlike blue or yellow stones, whose colours derive from trace elements such as boron or nitrogen, pink diamonds acquire their colour through structural distortion during their journey through the Earth’s crust. Immense heat and pressure alter the crystal lattice, bending light in a way that produces the characteristic rosy tone. This delicate interplay of nature’s forces gives rise to one of the most coveted colours in the world of gemstones.
Historically, Type IIa pink diamonds were first discovered in India’s legendary Golconda region, the birthplace of some of the world’s most celebrated gems. In later centuries, notable examples emerged from Brazil and Africa, such as the 70.39-carat Empress Rose and the 28.15-carat Agra, both of which remain icons of pink diamond heritage. The 6.95-carat stone offered by Phillips continues this lineage, marrying old-world rarity with contemporary brilliance.
Considering recent market performances for Fancy Vivid Purplish Pink diamonds, I estimate the final price could reach approximately €550,000 to €600,000 per carat. This projection reflects not only the stone’s exceptional colour saturation and substantial size, but also its VVS2 clarity and Type IIa purity—qualities that collectively position it within the upper echelons of the coloured diamond market.
In an era where collectors increasingly seek tangible rarity and beauty that transcends trends, this 6.95-carat Fancy Vivid Purplish Pink diamond stands as both an aesthetic masterpiece and an investment-grade treasure. When it appears under the lights of Geneva, it will undoubtedly capture not only the eyes of connoisseurs, but also the enduring fascination of all who understand that true beauty, like this diamond, is born under pressure.
