Eva London Blue Topaz Engagement Ring in 14K Solid Yellow Gold

The Eva looks like something inherited — a ring with a past, even though its story starts with you. This London blue topaz engagement ring frames a natural emerald-cut stone the color of deep ocean water in intricately detailed solid yellow gold, with your choice of moissanite or natural diamond accents completing its old-world sparkle.

The Deepest Blue Topaz There Is

London blue is the darkest, most saturated shade in the blue topaz family — inky teal in low light, glowing steel-blue in the sun. The Eva’s natural center stone measures 8.0 x 6.0 mm and carries approximately 1.6 carats, with the remarkable clarity this gem is prized for. At 8 on the Mohs scale, topaz is well suited to a ring worn daily. Blue topaz is also December’s birthstone — see our December birthstone guide — and carries centuries of calming, clarifying symbolism you can read about in topaz meaning and symbolism.

Why the Emerald Cut Suits It

Where brilliant cuts scatter light into sparkle, the emerald cut’s long step facets open windows into the stone — a hall-of-mirrors effect that lets you look down into that deep blue rather than just at it. It is the cut that rewards rich color, which is exactly what London blue topaz has to give. The clean geometry also plays beautifully against the Eva’s ornate vintage frame; if the shape speaks to you, explore more emerald cut engagement rings.

A Vintage Frame in Solid Yellow Gold

Intricate detailing and a slender band — averaging just 1.7 mm — give the Eva its romantic, heirloom character, echoing the vintage and antique engagement ring tradition while being newly handmade for you. It is offered in three karats of solid yellow gold, selectable from the drop-down: 10K, the hardest and most affordable; 14K, the most popular balance of warmth, durability, and value; and 18K, the richest gold content for the deepest yellow hue. Every option is solid gold through and through, like the rest of our solid gold rings. Not sure which karat suits you? Our 10K vs 14K vs 18K karat guide walks through color, durability, and value so you can choose with confidence.

Choose Your Accent Stones

The halo of small stones framing the center is yours to define:

• Moissanite — D color, VVS1 clarity, 9 on the Mohs scale. A real lab-grown gemstone with exceptional brilliance and even more fire than diamond.
• Natural diamond — G/H color, I1 eye-clean clarity, 10 on the Mohs scale, conflict-free. The heirloom-classic choice.

Either way the accents stay quietly supportive, letting the blue center lead. If you love a colored center stone, there is a whole world of gemstone engagement rings to compare — or let our guide to matching a gemstone to your birth month point the way.

Sizing & Care

The Eva is handmade to order in your exact size, with half and quarter sizes available — and because ring sizers and mandrels can vary up to half a size between jewelers, we recommend measuring with our ring sizing guide before ordering. Care is simple: warm water, mild soap, and a soft brush restore the topaz’s glassy shine. Avoid sharp knocks and sudden extreme heat, store the ring in its box, and it will keep its deep blue clarity for decades. An optional professional appraisal is available from the drop-down menu.
