Treatment disclosure, please read

These sapphires are glass filled (also called lead-glass filled or fracture filled). Natural fractures in the stone have been filled with glass to improve transparency and colour. This is a common treatment for affordable sapphire, and it's the reason these large stones are priced far below heated or untreated sapphires. Glass-filled stones need gentle care (see Care below).

Why a cabochon

A smooth, domed cabochon shows colour rather than sparkle. Light pools inside the dome, giving a deep "liquid blue" look, and the natural silk adds a soft glow.

Design ideas

  • Statement drop or stud earrings, using one stone each
  • A bold cocktail ring or a men's cabochon ring
  • Pendants and focal pieces
  • Bezel or prong settings in silver or gold

  • I absolutely love this 1930s sapphire rose cut from Roho Jewels! The sapphire is even more lovely than I imagined, and I can’t wait to make something with it. Leander was super prompt and communicative, responding to any questions that I had quickly and shipping the stone out right after I purchased it. I can’t recommend his shop enough - thank you so much, Leander!
