This piece is set with moissanite — a silicon carbide gemstone with its own GRA certificate. It is not a natural diamond and not a lab-grown diamond.

Exceptional size in the world’s most beloved cut — the 6.65ct DEW White Moissanite Round Solitaire Ring in 18K Gold Vermeil on 925 Sterling Silver, GRA certified.

A 6.65ct round brilliant moissanite sits approximately 12mm in diameter — a truly commanding presence on any hand.

What diameter is a 6.65ct round moissanite?

At 6.65ct DEW, the round moissanite measures approximately 11.9–12.1mm in diameter. For context: a standard US quarter coin is 24mm, so this stone is roughly half the diameter of a quarter. In fine jewelry terms, 6ct+ rounds are categorically “statement” sized — significantly above the national average engagement ring size of 1–1.5ct. The stone will produce refracted light visible across a room under standard indoor lighting.

How do you choose a ring setting for a very large round moissanite?

For stones above 5ct DEW, prong count becomes important — more prongs (6 rather than 4) distribute the stone’s weight and reduce the risk of loss if a single prong tip chips. A high-profile solitaire setting maximises light exposure from all angles. A low-profile setting is better for active lifestyles as the stone sits closer to the hand and is less vulnerable to impact. GemHub & Co. solitaire rings for large stones are set in 6-prong configurations to ensure the stone is safely secured.

Size guide

Most GEMHUB & CO. rings ship in US size 7. Custom sizing is available on request – email [email protected] and we will confirm before crafting.

Use a ring that fits the desired finger.
Measure the internal diameter of the ring in millimetres. Make sure your ruler starts at the 0 mm mark.

Between two sizes? Choose the larger one for comfort. Wider bands usually need a slightly larger size.
