Blue Sapphire Pair 7.90 ct, 9x7 mm Oval Cabochons – Glass-Filled Ceylon Stones
Every stone is described as it is.
Style ID: RJ-062766
Looking for big blue cabochons for your next design? This is a pair of Sri Lankan blue sapphire cabochons, nearly 4 carats each, with a high dome and a deep royal blue colour. They're made for jewelry makers and anyone who wants bold sapphire earrings, a statement ring or a pendant on an accessible budget. Please read the treatment note below: these stones are glass filled, and the price reflects that.
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).
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.

At Roho Jewels, everything begins with the stone. Every natural gemstone we offer is hand-selected in our Toronto studio. These are real, earth-mined sapphires, rubies and emeralds, and genuine pearls, never synthetics, and every stone is described honestly so you know exactly what you're buying. Our goal is simple: real gemstones, real craftsmanship and real value, without traditional retail prices.

Beautiful sapphires, fast shipping, and thoughtful high quality packaging. Thank you!
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!
I bought these emerald earrings for my daughter, and we absolutely love them. They are beautiful, excellent quality, and exactly as pictured. They arrived on time and exceeded our expectations. I highly recommend this shop.
