How Buying Works

1

Message us with your budget and stone preference

Tell us what you're looking for over WhatsApp — no form, no account.

2

Confirm your design and ring size

We agree on the setting, metal, and size before we ask for a deposit.

3

Deposit

Sourcing a specific stone takes real time and effort, so we ask for a deposit before searching begins — it secures your order and starts the sourcing process. If we're unable to source a stone that matches your requirement, the deposit is refunded in full.

4

We source the stone and send certificate details

Diamonds are chosen by certificate rather than physical sourcing, so this step is usually quick — we share graded stone options that fit your brief.

5

Production

Once the stone and design are confirmed, production begins in our Colombo workshop — allow 2–4 weeks.

6

Collect or ship

Collect in person in Colombo, or we arrange tracked, insured shipping if you're overseas.

We respond within hours.

If we're unable to source a stone that matches your requirement, your deposit is refunded in full.

Frequently asked questions

How much does a diamond engagement ring cost in Sri Lanka?

Lab-grown diamond rings range from LKR 215,000 (0.5ct) to LKR 1,000,000+ (1.5ct+). Natural diamonds start from LKR 565,000 for a 0.5ct stone and rise sharply above 2ct.

Is a lab-grown diamond a real diamond?

Yes. A lab-grown diamond is chemically and physically identical to a mined diamond — the same carbon structure, the same hardness (Mohs 10), the same optical properties. IGI and GIA certify both using the same standards.

Should I choose natural or lab-grown?

If resale value and geological rarity matter to you, choose natural. If you want maximum size and quality for your budget and plan to wear the ring rather than sell it, lab-grown is the more rational choice at current prices.

Do you offer both natural and lab-grown as ready-to-browse collections?

Yes — browse lab-grown diamond engagement rings or natural diamond engagement rings separately, or see everything together in this collection.
