Blue Topaz Engagement Rings

Yes — blue topaz is a Mohs 8, harder than amethyst, garnet, or peridot and a sound everyday choice. Because topaz has a cleavage direction, we suggest a protective bezel or halo for very active hands, which guards against an unlucky knock while keeping the bright blue on full display.

Most blue topaz on the market — including ours — starts as colorless topaz that is treated to develop its blue, an industry-standard, stable process that does not fade in ordinary wear. We are upfront about this: the color is permanent for daily life, and our concierge can source an untreated or certified stone on request.

Blue topaz is one of the most affordable ways into a vivid blue center, starting around $699 all-in — setting, center, and sizing included, with nothing extra at checkout. The all-in price updates with the center carat you choose.

Blue topaz is a traditional December birthstone and the 4th-anniversary gem, so a blue topaz engagement ring is a fitting choice for a winter proposal or an early anniversary.
