About Us

Blanchet & Co. was founded on a simple idea: a diamond ring should feel as significant as the moment it marks. We specialize exclusively in white gold diamond rings with bold, generous center stones — pieces built to be the focal point of a life, not just an accessory to it.

Our Craft

Every Blanchet & Co. ring is set in 18k white gold and built around a diamond of real substance — we don't deal in accent stones dressed up as statement pieces. Each center diamond is GIA certified, so what you see is backed by an independent, internationally recognized grading standard.

Our Promise

  • GIA certification with every ring
  • Complimentary one-time resizing within 60 days of purchase
  • 18k white gold construction on every piece, no plating
  • Signature packaging designed for the moment you hand it over

We're a young house, based in Australia, built by people who think an engagement ring is worth getting exactly right. Thank you for considering us for yours.
