3 Carat Marquise Cut Platinum Moissanite Ring+ 3.0-Carat Marquise Forever One Moissanite

Moissanite actually produces more sparkle than a diamond, with a dispersion rating of 0.104 compared to a diamond's 0.044. Its double refraction creates rainbow-colored flashes that are particularly visible in direct light. Some people love this fire; others prefer the whiter, more restrained sparkle of a diamond.

Platinum is among the best choices for people with metal sensitivities. It is typically used at 95% purity (950 platinum), with no nickel in the alloy. This makes it fully hypoallergenic and suitable for people who react to the nickel content in white gold. If allergies or sensitive skin are a concern, platinum is the gold standard.

A 3 carat stone is well above average and a great choice for someone who wants their ring to look expensive and elevated without crossing into the ostentatious territory you hit at 4-5 carats. A comparable lab-grown 3 carat stone can be found for $3,000 to $8,000 depending on quality grades. The price difference at this size is extraordinary, which is one of the most compelling reasons couples choose lab diamonds for larger center stones.

Yes, marquise cuts are prone to the bow-tie effect, a dark shadow across the center of the stone where light is not returned efficiently. A faint bow-tie is common and acceptable. A strong, dark bow-tie is undesirable. Cut quality and proportions determine how pronounced the bow-tie is, making it important to evaluate the specific stone rather than just relying on specs.
