Compare
A lab-grown diamond ring gives you the same brilliance as a mined diamond at roughly 40% of the price. The stone is identical at a molecular level. Same carbon, same crystal structure, same hardness. The only difference is that it was grown in a lab instead of pulled from the earth.
Ring types
Engagement rings are the most popular. Cocktail rings let you go bigger (2-5 ct centre stones) without the natural-diamond price tag. Bands and eternity bands are the companion pieces. Stacking rings and cocktail bands work on their own or alongside an engagement ring.
By shape
Every ring is available in multiple diamond shapes. Round is the classic. Oval elongates the finger. Emerald and Asscher are more architectural. Pear, marquise, and cushion each carry their own signature.
By carat
Shop by centre stone weight: 1 ct, 1.5 ct, 2 ct, 3 ct, or 4 ct+.

GIA grading report for every centre stone above 0.30 ct. 18K solid gold (yellow, white or rose), hallmarked. One free resize within 60 days. Lifetime cleaning and prong checks. 30-day returns on non-bespoke pieces.

Frequently Asked Questions
Are lab-grown diamond rings real?
Yes. Lab-grown diamonds are chemically, physically and optically identical to mined diamonds. GIA grades them on the same 4Cs scale and they sparkle the same way.
How much cheaper are lab-grown diamond rings?
Roughly 40-70% less than a comparable natural diamond ring. A 2 ct lab-grown solitaire typically costs what a 1 ct natural solitaire would.
Will a lab-grown ring last a lifetime?
Yes. Diamond is the hardest natural material. With basic care it will last forever. The 18K gold setting will need a professional prong check every 2-3 years, which we do free for life.
Can I tell the difference between lab-grown and natural?
Not with the naked eye or a loupe. A gemologist needs specialist equipment to distinguish them. Every Riyanika lab-grown diamond is laser-inscribed with its GIA report number for transparency.
Do lab-grown rings come with a GIA certificate?
Yes. Every centre stone over 0.30 ct ships with its original GIA grading report. Smaller accent stones come with a Riyanika quality certificate.
Can a lab-grown diamond ring be resized?
Solitaires, halos and three-stone rings can usually be resized up or down two sizes. Eternity and half-eternity bands have limited resize range because of the continuous diamond setting. First resize within 60 days is free.
