Brilliance — which stone sparkles more?

Brilliance is measured by a stone's refractive index — the degree to which it bends light back toward your eye. A higher refractive index means more sparkle. Fire is a separate quality: the coloured rainbow flashes a stone produces in light, measured by its dispersion rate.

In practice: moissanite produces vivid, coloured flashes — what IDHANI calls the signature rainbow fire — particularly striking in natural sunlight and evening lighting. Diamond produces a whiter, more restrained sparkle. Neither is objectively better. But if you want a stone that commands a room, moissanite's fire is unmatched.

Hardness — which stone is more durable?

Durability is measured on the Mohs Hardness Scale, the global standard for gemstone scratch resistance. The scale runs from 1 (softest) to 10 (hardest). A stone's hardness determines how it handles daily contact with surfaces, other jewellery, and general wear.

The 0.75-point difference between moissanite and diamond on the Mohs scale is irrelevant in daily life. The only thing that can scratch moissanite is a diamond. Everything you encounter daily — keys, handbag clasps, countertops, other jewellery — cannot scratch it. For rings, earrings, mangalsutras, and necklaces worn every day, moissanite is an entirely practical choice.

Does moissanite look fake?

This is the question most people hesitate to ask directly. The honest answer: no — not to the naked eye, and not to most standard testing equipment either.

Moissanite is not cubic zirconia. It is not glass. It is a real, certified gemstone — silicon carbide — with its own chemical identity, measurable hardness, and verifiable optical properties. Standard diamond testers cannot distinguish moissanite from diamond because both conduct heat similarly. A dedicated moissanite tester or advanced gemological equipment is required to tell them apart scientifically.

To anyone looking at your jewellery in normal life — at a wedding, at work, at a family gathering — moissanite is indistinguishable from diamond. The only visible difference, to someone who specifically knows what they are looking for, is the nature of the fire: moissanite throws more coloured light, diamonds produce whiter sparkle. To most people, moissanite simply looks like a very brilliant stone. Which, of course, it is.

Every moissanite stone in IDHANI jewellery is IGC-certified — the same rigour applied to diamond certification in India. You receive a certificate confirming the stone's authenticity, colour grade, and quality.

Ethical sourcing — does origin matter?

Mined diamonds carry documented concerns: environmental destruction from open-pit mining, displacement of communities, and a significant carbon footprint from extraction, processing, and global transportation. The Kimberley Process addresses conflict diamonds but does not resolve the environmental and community impact of mining itself.

Moissanite is entirely lab-grown. No earth is disturbed. No communities are displaced. The carbon footprint is a fraction of mined diamond production. For buyers who care about where their jewellery comes from — and increasingly, urban Indian buyers do — moissanite is the straightforward, clean-conscience choice.

Price — the real difference in India

This is where the comparison becomes most striking. A 1-carat mined diamond of good quality (VS clarity, F-G colour grade) in India costs between ₹2,50,000 and ₹4,00,000 — before the setting. That is a once-in-a-decade purchase for most households.

A comparable moissanite — same visual carat weight, IGC-certified, set in 925 Sterling Silver with 18KT Gold Vermeil — costs a fraction of that. At IDHANI, solitaire rings start from ₹2,999 and our 1.2-carat pieces range from ₹5,000 to ₹11,000.

The price difference does not reflect inferior quality. It reflects the absence of a mining supply chain. You are paying for the stone and the craft — nothing else.

The full comparison at a glance

The one area where diamond has a clear advantage is resale value. If you are buying jewellery as a financial investment, a mined diamond holds more resale value than moissanite. For every other measure — brilliance, durability, ethics, wearability, and price — moissanite holds its own or leads.

Is moissanite right for an engagement ring in India?

On the specs alone — hardness 9.25, higher brilliance than diamond, permanent fire — moissanite is entirely suitable for an engagement ring. For the full answer, which covers social perception, family expectations, and the real trade-offs, that is a different kind of question.
