A lab-grown diamond engagement ring is the right choice when you want a larger, cleaner centre stone without doubling your budget. A 2 ct lab-grown solitaire typically costs what a 1 ct natural solitaire would. Every Riyanika lab-grown engagement ring is made in 18K solid gold and set with a GIA-certified centre stone.
Setting styles
The solitaire is the most popular. One diamond, nothing else competing with it. A halo surrounds the centre stone with a ring of smaller lab-grown diamonds, which makes the centre look roughly half a carat bigger. A three stone setting is traditional and symbolic. A pavé band runs tiny diamonds along the shank for extra sparkle.
Carat weights
We stock from 0.50 ct to 5 ct+. The most popular size is 2 ct. See our 2 carat collection or 1 carat, 1.5 carat, and 3 carat.
How our lab-grown rings are made
Every centre stone is graded by GIA and laser-inscribed with its report number. We only use stones graded Excellent or Very Good cut, F-G colour, and VS clarity or better. The 18K gold setting is hand-finished and hallmarked in our workshop.
Every ring is customisable

Frequently Asked Questions
Will she know it is lab-grown?
Only if you tell her. Lab-grown diamonds are visually identical to natural diamonds. A jeweller needs specialist equipment to tell them apart.
What carat size should I get for a lab-grown engagement ring?
Most Riyanika customers buy between 1.5 ct and 2.5 ct because lab-grown pricing lets you go bigger without overspending. On a size 6 finger, 2 ct looks substantial without being overwhelming.
How much does a lab-grown engagement ring cost?
Our lab-grown engagement rings start at around $1,200 for a 1 ct solitaire and rise to $8,000 for a 3 ct halo. For the same budget, you get roughly 60% more diamond than you would with a natural centre stone.
Can I upgrade a lab-grown ring to a larger stone later?
Yes. Our lifetime upgrade programme lets you trade in your lab-grown engagement ring and put 100% of its value toward a larger piece at any time.
Are lab-grown diamonds durable enough for daily wear?
Yes. Diamond is the hardest natural material (10 on the Mohs scale) and lab-grown has the same hardness. It will last as long as a natural diamond. Forever, with normal care.
Do lab-grown engagement rings come with a certificate?
Every centre diamond over 0.30 ct ships with its original GIA grading report. Smaller accent stones are covered under a Riyanika quality certificate.
