Lab-grown diamond rings in Sri Lanka
A lab-grown diamond is the same stone as a mined diamond — same chemical composition, same optical properties, same hardness (Mohs 10). The only difference is origin. For buyers in Sri Lanka, that difference translates into something concrete: a certified 0.5ct lab-grown diamond solitaire in 18K gold from LKR 195,000, where the nearest natural diamond equivalent starts at LKR 750,000+.
Every ring is made to order in our Colombo workshop. Every stone is IGI or GIA certified. Browse the options below or WhatsApp us to discuss a custom design at your budget.

Certified stones, every time
Every lab-grown diamond we use is certified by an internationally recognised gemological authority — IGI (International Gemological Institute) or GIA (Gemological Institute of America). The certificate grades cut, colour, clarity, and carat weight, and explicitly confirms the stone is lab-grown.
The quality difference between a D/VVS1 and an I/SI2 stone is meaningful — optically and in price. When you order from us, you know exactly what grade you’re getting before the ring is made. The certificate ships with every finished piece.
Ring styles
Lab-grown diamonds suit every classic engagement ring style. We make the following in 18K gold:
- Round solitaire — one center stone in a prong or bezel setting. The most timeless option and the most accessible entry point. A well-cut 0.5ct stone in a clean solitaire delivers more visual impact than a larger, poorly cut stone in a busier setting.
- Oval halo — an oval lab-grown diamond surrounded by a ring of smaller diamonds. Visually larger than the carat weight suggests. One of the most popular designs for buyers who want maximum presence at a controlled price.
- Pavé band — a center solitaire with small diamonds set into the band on both sides. Adds sparkle across the full ring, not only at the center. Works equally well in white, yellow, or rose gold.
- Three-stone — a center diamond flanked by two smaller stones. Traditionally represents past, present, and future. Creates a substantial, layered look that photographs exceptionally well.
- Custom design — have a specific style in mind? Send us a reference image on WhatsApp. We’ll quote the design, confirm materials, and build exactly what you’re envisioning. No design is off the table.
All styles are available in 18K white gold, yellow gold, or rose gold. The metal colour is a purely aesthetic choice — the price at the same karat is similar across all three.

The difference is origin — and, at current prices, a significant cost gap. A lab-grown diamond is created in a controlled environment using the same carbon-based process that forms natural diamonds underground over millions of years. The end result is chemically, physically, and optically identical. A gemologist examining both under a microscope cannot distinguish them without specialist detection equipment.
Lab-grown diamonds typically cost 40–70% less than equivalent natural stones. That gap has been widening as production efficiency improves. For a buyer who wants the diamond aesthetic — the brilliance, the hardness, the cultural weight — at a sensible price, lab-grown is the rational choice in 2026.
The one real trade-off: lab-grown diamonds have declining resale value as production costs fall. If you plan to wear the ring for a lifetime rather than resell it, this matters less than it sounds. Our lab-grown vs natural diamond guide covers the full comparison — including resale, certification, and the environmental angle.
How to order your ring
Every lab-grown diamond ring is made to order. The process from first message to finished ring:
- WhatsApp us — tell us your budget, preferred style, and ring size (or we’ll send a ring-size guide if you’re unsure). We’ll send certified stone options within your range.
- Choose your stone and design — we’ll share graded options with certificate details. Once you confirm the stone and setting, we lock in the design and provide a production timeline.
- Production — most rings are ready in 2–4 weeks from design confirmation. Complex settings can take up to 5 weeks. We give you an exact date upfront.
- Delivery — free shipping across Sri Lanka, with international shipping available. The ring arrives with its gemological certificate and packaging.
Frequently asked questions
Yes. A lab-grown diamond is chemically and physically identical to a mined diamond — pure carbon in a cubic crystal structure, with the same hardness (Mohs 10), the same refractive index, and the same optical properties. The difference is origin. IGI and GIA certify lab-grown diamonds using the same standards applied to natural stones. For the full breakdown — including whether they're worth it — see our dedicated guide.
Lab-grown diamond rings in 18K gold start from around LKR 195,000 for a 0.5ct round solitaire. A 1ct oval halo design typically falls in the LKR 350,000–500,000 range. The final price depends on stone grade and setting complexity. All rings are made to order — no finished gold stock is held.
For most buyers, yes. You get the same diamond — same hardness, same certification, same brilliance — at 40–70% less than a natural stone. The trade-off is lower resale value as lab-grown production costs continue to fall. If you’re buying a ring to wear rather than to sell, lab-grown is the sensible choice at current prices.
Not with the naked eye, and not with standard gemological equipment. A professional gemologist requires specialist instruments (HPHT/CVD detection tools) to distinguish the two. The certificate that accompanies every stone confirms its origin. On the finger, both are visually indistinguishable.
Most rings are ready within 2–4 weeks from confirming the design; complex settings can take up to 5 weeks. Delivery within Sri Lanka takes 2–4 days after the ring is complete. If you have a specific date in mind, mention it when you first message us and we’ll work to it.
Yes. We ship internationally with full tracking. The ring ships with its gemological certificate. WhatsApp us for shipping rates and timelines to your country.
