Asscher Cut Vintage Halo White Sapphire Engagement Ring in Sterling Silver

Step into the Great Gatsby era. This white sapphire engagement ring centers a 7 × 7mm Asscher-cut genuine white sapphire — roughly two carats of colorless corundum — inside an octagonal art deco halo of bright simulated diamond. Set in solid 925 sterling silver with a luminous rhodium finish, it is an architectural, old-Hollywood proposal ring for anyone who wants geometric glamour built around a real gemstone.

A Great Gatsby silhouette in silver

The Asscher cut — a square step cut with softly cropped corners — was the signature shape of the 1920s, and here it anchors a symmetrical octagonal halo edged in delicate milgrain beading. Four prominent accents mark the compass points while pave sparkle fills the frame, so the whole ring face reads as one crisp, architectural composition. It is a deliberately vintage alternative to the soft round solitaire, and it sits beautifully within our wider range of sapphire engagement rings. If the colorless, white-on-white palette is what draws you in, our dedicated white sapphire rings collection gathers more of the same understated brilliance.

The white sapphire at its heart

The center stone is a genuine lab-grown white sapphire — real corundum, the very same mineral species as blue sapphire and ruby, simply in its colorless form. Because it is grown rather than mined, you get an authentic precious gemstone with identical chemistry and identical hardness at a far more accessible price. And that hardness is the headline: white sapphire measures a superb 9 on the Mohs scale, second only to diamond, which makes it exceptionally scratch-resistant and ideal for the daily wear an engagement ring endures. For a century it has been the classical diamond alternative, prized for clarity and a calm, understated sparkle rather than fiery flash. If you are weighing colored versus colorless stones, our comparison of aquamarine versus a sapphire engagement ring is a helpful read.

A vintage halo of simulated diamond

The halo and its accents are simulated diamond — cubic zirconia cut for maximum white fire. It is a bright, budget-friendly way to wrap the Asscher center in continuous sparkle, and the cool flash of the CZ makes the colorless sapphire at the middle read even more luminous. Prefer moissanite or lab-grown diamond accents on a solid gold version instead? Message us and we will tailor it.

Sterling silver with a rhodium finish

The band is solid 925 sterling silver — 92.5% pure silver throughout, never plated base metal — finished with a layer of rhodium, the same precious metal used on fine white gold. That rhodium finish gives the ring a bright, mirror-white luster and adds a protective shield against tarnish and everyday scratches, keeping the white-on-white palette crisp. Genuine sterling silver is also nickel-free and hypoallergenic, so it will not turn your finger green.

What a sapphire ring symbolizes

For thousands of years sapphire has stood for wisdom, loyalty and sincerity — fitting emblems for a lifelong promise. White sapphire adds its own note of clarity and steadfastness, which is part of why it has endured as a bridal stone. Sapphire is also the September birthstone and the traditional fifth and forty-fifth anniversary gem, so this ring quietly layers in gift-occasion meaning. Our complete guide to sapphire meaning explores the lore in full, and our overview of sapphire engagement rings covers how to choose one.

Sizing & care

Choose your size at checkout; the band is true to size and comfort-fit, and if you are unsure we can send a complimentary ring sizer before you order. Should the fit need adjusting, resizing is available and starts from a modest fee. White sapphire is one of the toughest engagement stones you can wear, so it handles daily life with ease — simply clean it with warm water and a soft brush, avoid harsh chemicals like chlorine and bleach that can dull the rhodium, and store it apart from other pieces so the milgrain and halo do not catch. The design also stacks beautifully with a slim band from our sapphire wedding bands collection.
