WHAT'S INCLUDED — two Bianca rings in 9k gold, in the pair of gemstones of your choice.
Individual value €980 · Stack €880 — you save €100.
Choose a size for each ring: the first will feature the first gemstone in the pair, the second the other.
Made to order for you: three weeks. One parcel, one delivery.
Two colours, one effortless gesture. The simplest way to bring character to even the most pared-back look. From the energy of complementary colours to the harmony of neighbouring tones, each pairing creates its own balance of contrast and cohesion — because every colour carries its own energy, emotion and sense of self.

  • Blue Agate + Carnelian — blue & orange
  • Amethyst + Citrine — purple & yellow
  • Blue Agate + Amethyst — blue & purple
  • Green Agate + Citrine — green & yellow
  • Blue Agate + Citrine — blue & yellow
