Cushion Cut Natural London Blue Topaz Engagement Ring in 14K Solid Rose Gold

This cushion cut engagement ring centers a natural London blue topaz — a deep, saturated ocean-blue stone (7×7mm, ~2.4ct) — in a vintage art deco setting of solid rose gold, with your choice of moissanite or natural diamond accents. Choose your karat — 10K, 14K, or 18K. The pillowy cushion cut and rich blue against warm rose gold make it a distinctive, romantic alternative engagement ring or November-birthday gift.

The cushion cut

A cushion cut is a square shape with softly rounded corners — like a pillow — that pairs a vintage, romantic character with broad, open facets that show off a colored stone's depth. Here it lets the London blue topaz glow with its full ocean-blue saturation, framed by the geometry of an art deco setting. A colored center like this is a lovely way to break from convention; our guide to non-traditional engagement rings is a helpful place to start.

The natural London blue topaz

The center is a genuine natural London blue topaz — cushion cut, 7×7mm, ~2.4ct — in the deep, slightly steely blue that London blue is prized for. Topaz sits at 8 on the Mohs scale, hard and well suited to ring wear with normal care. Genuine natural topaz, not simulated. If you love a colored center, you'll find more options among our gemstone engagement rings.

Choose your accent stones

• Moissanite (D color): lab-grown, VVS1, 9–9.25 Mohs — brilliant, accessible, sustainable.
• Natural diamond (G/H, I1): conflict-free mined diamonds, eye-clean, 10 Mohs — traditional and enduring.

Choose your gold: 10K, 14K, or 18K solid rose gold

This ring is solid rose gold — the metal itself, not plating or vermeil over a base metal — with your karat selected from the drop-down menu. 10K is the most durable and most affordable; 14K is the classic balance of warm rose color and everyday strength (our default); 18K carries the highest gold content and the richest rose hue. The warm pink metal makes a beautiful complementary contrast with the cool blue topaz, and the color is permanent: it won't wear off and won't turn your skin green. Our 10K vs 14K vs 18K gold guide breaks down the karat differences. Also available in white or yellow gold on request.

Sizing & care

London blue topaz is hard enough for regular wear; clean with warm soapy water and a soft brush, and avoid harsh chemicals and prolonged heat. Please reference our sizing guide before ordering. An optional written appraisal can be added from the drop-down menu (non-refundable once completed).
