6 Carat Engagement Rings

Six carat engagement rings in solid 14K gold — every six carat ring we make, in lab grown diamond and in moissanite.

Which stone reads as a diamond?

At six carats this question matters more than it does at one. A lab grown diamond is a diamond: same carbon crystal, same hardness, graded by the same laboratories, and nobody looking at it will think otherwise. Moissanite is its own gemstone and at six carats its extra fire is very visible — it throws colored flashes a diamond does not. Some people choose it deliberately for exactly that. Others find that a stone this large draws enough attention that they want it to be unambiguously a diamond. Neither answer is wrong, but it is worth deciding before you shop rather than after.

Size on the hand

A six carat round is roughly 11.7mm across, close to the full width of an average finger. The step up from five carats is real but modest, because carat measures weight and not surface area.
