The Bulgari signature and a rare pink diamond are a combination that usually results in a resounding result. In Turin, it was confirmed: a record for Aste Bolaffi and a very strong signal that the pink diamond category is holding its own.
4C parameters and documentation
Color: Fancy Intense Pink (GIA), Type IIa
Weight: 3.18 ct
Purity: VS2
Cut: rectangular with cut corners (cut-cornered step/modified brilliant)
Certificate: GIA
The term Fancy Intense Pink isn't a single shade, but a color range defined by GIA (tone and saturation). In practice, a "powdery" pastel more often falls into the Fancy Light Pink or Fancy Pink category; if it reaches Intense, it still looks more vibrant than a typical pastel. A strong, "panty-like" pink falls into the Fancy Intense Pink range, and with even higher saturation, it falls into the Fancy Vivid Pink category. The color perception is further influenced by modifiers (e.g., purplish/orange/brownish pink), the cut and size of the stone (radiant and cushion often enhance the face-up color), the color of the setting metal (pink or yellow gold warms and enhances the pink; platinum or white gold cools it), as well as fluorescence and lighting conditions. Therefore, with pink diamonds, it's always worth examining the stone in various lights, not just the report itself.
Frame and design
Trombino model in platinum, 1970s. Bulgari's signature architecture features broad shoulders and accent diamonds: a total of 64 pieces (round and baguette) weighing approximately 1.93 ct. The design accentuates the stone's length and allows it to "play" with light, while also adding the substantiality expected by vintage Bulgari collectors.

-
The Fancy Intense, Type IIa feature set and 3.18 ct weight scales demand above the market standard.
-
Pink diamonds are keeping the heat on: even beyond Geneva and Hong Kong, results are emerging that build a narrative about the category's enduring value.
-
For buyers: in pink stones, good design and provenance often weigh more than a single point of purity.
