Lab diamond and moissanite jewellery are no longer alternatives to the real thing — they are the real thing, for anyone who values ethics, beauty, and intelligence in equal measure. In 2026, the Indian market has never offered more options. The challenge is knowing which stores deserve your attention — and your budget.
Whether you're planning an engagement, marking an anniversary, or simply believing that fine jewellery shouldn't require a compromise, this guide cuts through the noise. We've evaluated every major online destination for lab diamond and moissanite jewellery in India on the criteria that actually matter: stone quality, certification, customisation, and value for the ₹30,000–₹1,00,000 buyer.
"The best piece of jewellery is not the most expensive one — it's the one made exactly for you, from materials you can verify and trust."
Quick Reference
Lab Diamond vs Moissanite — Which Is Right for You?
Before diving into the stores, here's a clear comparison of the two stone types this guide covers.
| Feature | Lab Diamond | Moissanite |
|---|---|---|
| Composition | Pure carbon — identical to mined diamond | Silicon carbide (SiC) |
| Hardness (Mohs) | 10 — the hardest known material | 9.25 — harder than sapphire or ruby |
| Refractive Index | 2.42 | 2.65–2.69 (more fire & rainbow sparkle) |
| Certification | IGI, GIA, or SGL (internationally recognised) | No independent gemological cert; quality graded by manufacturer (DEF VVS1 grade at Vaira) |
| Price per carat | ₹40,000 – ₹80,000 | ₹8,000 – ₹20,000 |
| Best for | Engagement rings, prestige, certified value | Maximum carat size on a mid-range budget |
| Available at Vaira | ✓ Yes — IGI/SGL certified | ✓ Yes — DEF VVS1 grade |
The Bottom Line
If the prestige and certification of a diamond matter to you, choose a lab-grown diamond. If you want the largest, most brilliant stone your budget allows, moissanite is an outstanding choice. Vaira is one of the very few Indian jewellers that offers both — with full customisation on either, and BIS-hallmarked gold on every setting.

Vaira — Best for Custom Lab Diamond & Moissanite Jewellery
vaira.co.in · Hyderabad, India · ₹30,000 – ₹1,00,000 · Lab Diamond & Moissanite
If you want a piece of jewellery that is truly yours — designed around your story, not pulled from a generic catalogue — Vaira is the standout choice in India for 2026. And what makes Vaira genuinely rare is that you're not limited to one kind of stone. Vaira offers both certified lab-grown diamonds and moissanite, with full end-to-end customisation on every piece.
Lab Diamond at Vaira
Vaira's lab-grown diamonds are IGI or SGL certified and carry the same chemical and physical properties as mined diamonds — available across a full range of cuts, colours, and clarities, and set in BIS-hallmarked 18KT gold. Every stone is selected for brilliance and integrity, not simply price point.
Moissanite at Vaira
For buyers who want extraordinary sparkle at a more accessible price, Vaira's moissanite collection is the answer. Moissanite has a refractive index of 2.65–2.69 — higher than diamond's 2.42 — meaning more fire and rainbow brilliance. At Vaira, every moissanite piece is set in the same BIS-hallmarked solid gold as the lab diamond range.
The Custom Process
- Share your vision — a sketch, a reference image, or simply an idea
- Choose your stone: lab diamond (IGI/SGL certified) or moissanite, in your preferred cut and size
- Select your metal: 14KT or 18KT gold, in BIS-hallmarked solid gold
- Approve CAD renders before a single tool touches the metal
- Receive a one-of-a-kind piece, crafted to last a lifetime
Who should shop here: Couples planning engagements or anniversaries, anyone who refuses to settle for mass-produced design, buyers who want both stone options — lab diamond and moissanite — under one roof, with full customisation.

Before You Buy
What to Check Before Any Purchase
Fine jewellery is a significant decision. Run through this checklist before committing to any online store — it takes two minutes and could save you considerably more.
- Certification: For lab diamonds, always confirm IGI, GIA, or SGL certification. Ask for the certificate number before placing any order and verify it on the certifying lab's website independently.
- Gold purity: The setting should be BIS-hallmarked solid 14KT or 18KT gold. Gold plating fades within months; BIS-hallmarked solid gold does not.
- Stone flexibility: Does the store offer both lab diamond and moissanite? A jeweller who understands both stones will guide you more honestly than one who sells only one.
- Customisation: Can you design your piece from scratch — with CAD renders before production — or are you limited to a catalogue? A piece made for you will always mean more than a piece made for everyone.
- Transparent pricing: Making charges and stone cost should be listed separately. Avoid any store that shows only a single bundled price with no breakdown.
- After-sales support: Check what warranty, repair, and exchange policies exist before you buy — not after something goes wrong.
