3 Carat Radiant Cut 18k Yellow Gold Lab Diamond Ring+ 3.0-Carat Radiant Lab Created Diamond

Yes. Lab diamonds are graded using the same 4Cs system as mined diamonds: cut, color, clarity, and carat weight. Certifications from labs like IGI, GIA, and GCAL are available. Reputable retailers provide certification documentation with every lab diamond so you know exactly what you are getting.

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.

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.

Both are rectangular or square brilliant cuts, but there are real differences. Princess cuts have sharp, pointed corners; radiant cuts have trimmed, beveled corners. The trimmed corners make radiant cuts more practical for daily wear since there are no vulnerable points to chip. Radiant cuts also tend to show slightly more color and fire in their sparkle pattern.

This 3ct radiant lab diamond in 18k yellow gold merits attention for its commanding size, dazzling fire, and rich metal warmth working in concert. The radiant cut combines an emerald-like outline with brilliant-cut facets, producing remarkable sparkle at three carats. The 18k yellow gold band provides 75% gold purity for a deeper, more saturated tone. Do Amore's Shark Tank-tested giving model funds clean water for one person with every ring purchased.
