Lab-grown diamonds are diamonds. Same carbon, same crystal structure, same brilliance. The only difference is that they were grown in a lab over a few weeks instead of pulled from the earth over a billion years. You get a bigger, cleaner stone for a fraction of the price, and the diamond still comes with a GIA grading report.
Why our customers choose lab-grown
Three reasons: price, size and ethics. A 2 carat lab-grown diamond typically costs what a 1 carat natural diamond costs. There are no mining-related disputes in the supply chain. And because lab-grown production is more precise, the stones tend to grade higher on clarity and colour for the same budget.
What you can buy
The collection covers every category. Engagement rings are the most popular. A classic solitaire or a halo with a 2 ct centre stone works beautifully. For everyday, look at our stud earrings, pendants, and tennis bracelets.
18K gold, hallmarked
Every piece is made in 18K solid gold. Yellow, white or rose. The full carat weight of gold is declared. No plating. We hallmark every ring, pendant and pair of earrings.
Certification and guarantees
Every centre stone above 0.30 ct is accompanied by its GIA grading report. Side stones are set with lab-grown diamonds of matching quality. Every piece is covered by our lifetime craftsmanship warranty and lifetime cleaning service.

Frequently Asked Questions
Are lab-grown diamonds real diamonds?
Yes. A lab-grown diamond is chemically, physically and optically identical to a mined diamond. The FTC in the US and the Gem & Jewellery Export Promotion Council both classify them as real diamonds. GIA grades them on the same 4Cs scale as natural stones.
How much cheaper are lab-grown diamonds?
Around 40-70% less than a comparable natural diamond. A 2 ct lab-grown engagement ring usually costs what a 1 ct natural engagement ring costs. The gap is bigger at higher carat weights.
Do lab-grown diamonds sparkle the same as natural diamonds?
Yes. Brilliance is a function of cut, not origin. A well-cut lab-grown diamond sparkles exactly the same as a well-cut natural diamond. We only stock stones graded Excellent or Very Good cut.
Will a jeweller be able to tell it is lab-grown?
Not with the naked eye or a loupe. A gemologist needs specialist equipment to distinguish lab-grown from natural. Every Riyanika lab-grown diamond is laser-inscribed with its GIA report number for transparency.
Do lab-grown diamonds hold their value?
Lab-grown diamonds depreciate faster than natural diamonds on the secondary market. If resale value is your priority, choose natural. If size, clarity and budget matter more, choose lab-grown. Most customers choose lab-grown because they plan to keep the piece.
Are lab-grown diamonds better for the environment?
Most of the energy used to grow a diamond today comes from renewable sources, and no mining is involved. The supply chain is also much shorter and more traceable than mined stones.
