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.
Frequently asked questions
Is the white sapphire a real gemstone?
Yes. It is a genuine lab-grown white sapphire — real corundum, the same mineral as blue sapphire and ruby, just colorless. Grown in a lab rather than mined, it has identical chemistry, hardness and durability to a natural white sapphire.
How durable is it for daily wear?
Very. White sapphire measures 9 on the Mohs scale, second only to diamond, so it resists scratches beautifully and is well suited to everyday engagement-ring wear. Avoid hard knocks on stone surfaces as general best practice.
Is white sapphire the same as a diamond?
No, and we like to be accurate about that. White sapphire is corundum; diamond is carbon. Both are colorless and very hard, but diamond returns more fire while white sapphire has a softer, more understated sparkle. It is a genuine precious gemstone chosen for its own merits, not a diamond imitation.
What is an Asscher cut?
An Asscher cut is a square step cut with cropped corners and concentric facets that draw the eye into the stone, creating a signature hall-of-mirrors depth. Developed in 1902, it became the defining shape of art deco jewelry, which is why it suits this vintage design so perfectly.
Are the halo stones real diamonds?
The halo and accents are simulated diamond (cubic zirconia), cut for a crisp white sparkle that frames the sapphire center. If you would prefer moissanite or lab-grown diamond accents on a solid gold version, message us for a custom quote.
How large does the ring look on the hand?
The center sapphire is about 2 carats, and the octagonal halo adds visual size so the ring face reads noticeably larger than the center stone alone. It has genuine presence while staying elegant rather than heavy.
What metal is the band?
Solid 925 sterling silver — pure silver throughout, not plated base metal — finished with rhodium for a bright white luster and extra protection against tarnish and scratches.
What does the rhodium finish do?
Rhodium is the same precious metal used to finish fine white gold. It gives the silver a mirror-bright, white-gold-like shine and adds a protective layer that helps the ring stay looking freshly polished.
Will sterling silver turn my finger green?
No. Genuine 925 sterling silver does not turn skin green — that reaction comes from low-quality base metals. This ring is nickel-free, hypoallergenic and finished in rhodium, so it is friendly to sensitive skin.
Can it be engraved?
Yes. Add a personal engraving of up to 16 characters at checkout — a date, initials or a short message. Engraved pieces are final sale, so please double-check the spelling.
What size should I order?
Select your ring size at checkout. If you are between sizes or unsure, contact us and we can help or send a complimentary sizer. Resizing is available afterward and starts from a modest fee.
Are the stones ethically sourced?
Yes. The lab-grown white sapphire has no mining footprint and the simulated diamond accents are ethically produced, so you can wear the ring with complete peace of mind.
Does it arrive gift-ready?
Every order ships in a free luxury velvet gift box and is backed by our lifetime warranty — ready for a proposal or to give as a keepsake.
