Colorless brilliance with an Art Deco soul. The Cordelia is a white sapphire engagement ring built around a genuine lab-grown white sapphire — a real corundum gem that ranks 9 on the Mohs scale — cradled in solid 925 sterling silver with a luminous rhodium finish. It is the icy, diamond-white look many couples want, delivered with the quiet confidence of a stone hard enough to wear every single day.

Inspired by the geometry and glamour of the 1920s, the Cordelia frames its oval center in clean, architectural lines that feel both heirloom and modern. It is a colorless alternative to a traditional diamond solitaire that still reads unmistakably bridal, and it sits beautifully within our wider range of sapphire engagement rings. If a bright, snow-white stone is exactly the palette you are after, you will find it echoed across our white sapphire rings collection.
The genuine white sapphire
White sapphire is a true corundum — the same mineral family as blue sapphire and ruby — simply grown without the trace elements that add color, leaving a clear, colorless gem. Because this stone is lab-grown, it is a genuine sapphire in every physical sense: identical hardness, identical composition, and a Mohs rating of 9 that places it just below diamond for scratch resistance. That makes it one of the most practical colorless stones you can choose for a ring worn daily. To understand how sapphire compares with other icy-blue and colorless options, our guide on aquamarine vs sapphire engagement rings is a helpful read.
Solid sterling silver with a rhodium finish
The band is crafted in solid 925 sterling silver and finished with rhodium — the same precious metal used on fine white-gold jewelry. That rhodium layer gives the ring a bright, mirror-white luster that flatters the colorless sapphire, and it adds a protective shield that helps resist tarnish and everyday scratches. It is the detail that lets sterling silver wear like something far more expensive. The band is also nickel-free and hypoallergenic, so it stays comfortable on sensitive skin.
What sapphire symbolizes
For centuries sapphire has stood for wisdom, loyalty and enduring devotion, which is part of why it has become such a meaningful engagement and promise-ring stone, and the September birthstone. A white sapphire keeps that heritage while offering a pure, luminous canvas for the moment you are marking.

Sizing & care
Choose your size at checkout. If you are between sizes or unsure, reach out and we will help — and if the fit is not quite right, resizing is available and starts from a modest fee. To keep the sapphire and rhodium finish at their brightest, remove the ring before showering, swimming or applying lotions, and store it in the velvet box when not worn. A soft, dry cloth restores the shine beautifully. A matching band from our sapphire wedding bands or a piece from our broader sapphire jewelry range completes the set.
Frequently asked questions
Is the white sapphire a genuine sapphire?
Yes. It is a genuine lab-grown white sapphire, meaning real corundum with the same composition and hardness as mined sapphire. Lab-grown simply describes how it was created, not whether it is real.
How durable is a white sapphire ring?
Very durable. Sapphire rates 9 on the Mohs scale, second only to diamond, so it resists scratches and everyday knocks exceptionally well. It is an excellent choice for a ring you plan to wear daily.
How is white sapphire different from a diamond?
Both are colorless and hard-wearing. Diamond throws more fiery, rainbow sparkle, while white sapphire has a softer, more silvery-white brilliance. Many couples love that it gives a classic diamond look at a fraction of the cost.
What metal is the ring made from?
Solid 925 sterling silver, finished with rhodium for a bright white luster and added 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.
What size is the center stone?
The oval white sapphire measures approximately 6 x 8 mm, around 1.4 carats, giving a generous, elegant presence on the finger without overwhelming the Art Deco setting.
Is it suitable as an engagement or promise ring?
Absolutely. Its colorless brilliance and durability make it a natural engagement ring, and it works just as beautifully as a promise ring or an anniversary gift.
Is the ring hypoallergenic?
Yes. It is 100% nickel-free and hypoallergenic, so it is safe for sensitive skin and will not turn your finger green.
Can it be resized?
Yes. Select your size at checkout, and if the fit is not quite right, resizing is available and starts from a modest fee. Contact us if you are between sizes.
How do I care for the ring?
Remove it before showering, swimming or applying lotions, store it in the velvet box, and buff with a soft dry cloth to restore shine. Gentle care keeps both the stone and the rhodium finish luminous.
Are the stones ethically sourced?
Yes. All of our stones are ethically sourced and conflict-free, 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.
Can I find a matching band?
Yes. Explore our sapphire wedding bands and wider sapphire jewelry collections to pair or stack alongside the Cordelia for a complete bridal look.
