Emerald lab-grown diamonds
A emerald cut is a step cut with long, clean facets that show clarity more than sparkle. Lab-grown stones cost far less per carat, so many buyers choose a larger size or a higher color.

Questions buyers ask
Are lab-grown diamonds real diamonds?
Yes. A lab-grown diamond is pure crystallized carbon with the same hardness, refractive index and chemical structure as a mined diamond. Gem labs such as IGI and GIA grade them with the same color, clarity and cut scales, and the report states that the stone is laboratory-grown.
How much cheaper is lab-grown than natural?
For the same size and quality, a lab-grown diamond usually costs a small fraction of a natural one. On our current price list a 1 carat round F-G VS lab-grown diamond is $420 and a comparable GIA-graded natural diamond is $5,200.
Which certificate comes with my diamond?
Lab-grown center stones and loose stones come with an IGI report. Natural diamonds of 0.30 ct and above come with a GIA report. The report number is laser-inscribed on the girdle, and we send you the report before we charge.
