1 Carat Round Cut 18k Yellow Gold Moissanite Ring+ 1.0-Carat Hearts and Arrows 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.

18k gold contains 75% pure gold, with the remaining 25% made up of alloy metals like copper and silver. This higher gold content gives 18k yellow gold a richer, more deeply saturated golden color than 14k. The trade-off is that it is softer and more susceptible to surface scratches compared to 14k.

The round brilliant is the most efficient cut for light return, and moissanite's higher refractive index takes that performance even further. At 6.5mm, a 1 carat round has a classic, proven presence on the finger. 18k yellow gold's warm depth (75% pure gold) gives the ring a traditional, heirloom character that has been popular for centuries and remains one of the most requested combinations.

The round brilliant cut was engineered specifically to maximize light performance. Its 57 or 58 facets are positioned to reflect and refract light with maximum efficiency, producing the most consistent sparkle of any diamond or gemstone shape. Its symmetry also means it looks good from every angle, which is why it has been the dominant engagement ring choice for over a century. At this size, 1 carat delivers the look most people picture when they think of an engagement ring. It is the original benchmark for a reason.

Purchasing a 1ct round moissanite in 18k yellow gold from Do Amore is an investment in stunning optics and genuine social good. The round cut is the most popular gemstone shape worldwide, and paired with moissanite's exceptional fire, the light performance is mesmerizing.
