AGL Certified Ceylon Blue Sapphire 1.15 ct Oval Step Cut – Natural Loose

Designing an engagement ring with character? This certified natural Ceylon sapphire is cut as an oval step cut, which gives it crisp, geometric reflections and a "hall of mirrors" depth instead of scattered sparkle. It's the look people want for Art Deco and vintage-inspired engagement rings, sleek bezel solitaires and east-west settings, and at just over a carat it's a classic ring size. It comes with an independent AGL report, so you and your jeweler know exactly what you're setting.

• Natural. Certified. Architectural. Made to be remembered.
• Natural Ceylon blue sapphire, 1.15 ct, oval step cut
• Rich medium to deep blue, eye clean to minimally included

What makes the step cut special

A brilliant cut scatters light in every direction. A step cut uses long, parallel facets instead, so you see:

• Crisp, geometric reflections rather than scattered sparkle
• Deep transparency, so you can look into the stone
• A "hall of mirrors" depth effect
• Clean, architectural symmetry

It looks intentional and refined rather than flashy, which is why it suits Art Deco, vintage-inspired and minimalist designs.

For the engagement ring buyer

• Just over 1 carat, a classic ring size
• About 6 × 5 mm, which fits standard oval settings
• Beautiful in a bezel solitaire or set east-west
• Mohs 9 hardness, made for everyday wear
• AGL certificate for you, your jeweler and your insurer

A gemstone for him: the men's signet ring

At Roho Jewels, we believe men deserve beautiful gemstones too. A natural Ceylon blue sapphire set into a signet ring is a bold, personal alternative to a plain metal signet: one-of-a-kind, full of character, and a ring he'll wear for decades and one day pass down.

• Signet face: at 6.36 × 5.53 mm, this stone suits a signet face of about 10–13 mm, a classic small signet or pinky ring
• Setting: flush (gypsy), bezel or half-bezel keeps it low and smooth, with no claws to catch on sleeves or gloves
• Depth: the stone is 3.5 mm deep, so ask your jeweler for a signet head at least 4.5 mm deep
• Metal: rich in yellow gold, sharp in white gold or platinum, rugged in oxidised sterling silver
• Wear: Mohs 9, second only to diamond, so it is tough enough for a ring worn every day
• Perfect for: husbands, fathers, grooms, graduates, milestone birthdays, or a signet he buys for himself

Why Ceylon
