The Story
Azure sets a band of deep blue sandstone into black tungsten. The stone is scattered with metallic flecks that catch light like a clear night sky, shifting as your hand moves.

It's the most quietly spectacular ring in the CELESTIUM collection: dark and understated until the light finds it.
Materials & Specs
  • Band: tungsten carbide, 9 on the Mohs scale. Highly scratch-resistant and holds its shape.
  • Finish: ion-plated black.
  • Inlay: blue sandstone with metallic shimmer, sealed behind protective epoxy.
  • Width 8mm · comfort-fit interior · typically 10–14g depending on size · sizes UK N½–Y (US 7–12).
  • REACH & GPSR certified and independently tested, so it's safe for most people.
  • Tungsten cannot be resized, so if you're not sure of your size, request a free ring sizer first. If the fit isn't right, we offer free size exchanges within 30 days.
  • Each ring is presented in Foundoria's signature eco-luxury packaging.

Care
Fine for handwashing, showering and everyday wear: the stone inlay is sealed behind epoxy, so water contact is no problem. Epoxy can be marked by abrasive surfaces, so remove the ring for weights, gritty manual work and anything that rubs. That's exactly what your free ENDURA silicone band is for. Wipe weekly with a soft dry cloth. See the full Ring Care Guide for more.
