Start Here: The Basics
Before you look at a single piece of jewellery, these two concepts will save you from the most common mistakes Indian buyers make.
1. The 4Cs — The Only Quality Framework That Matters
Every diamond is graded on Cut, Colour, Clarity, and Carat. Cut is the most important — it determines how much light a diamond returns to your eye. A well-cut 0.70ct stone will outshine a poorly-cut 1.00ct every time. Colour runs D (colourless) to Z (yellow); G–H is the sweet spot for Indian settings. Clarity ranges from Flawless to I3; VS2 or eye-clean SI1 is sufficient for most buyers.

2. IGI Certification — Your Only Protection
An IGI (International Gemological Institute) certificate is a third-party document that verifies the exact 4C grades of your diamond. Every diamond at My Carat ships with an IGI certificate. You can verify the report number on IGI's website before you buy. No certificate = no accountability.

Choose Your Piece
Solitaire Rings
India's most popular diamond purchase. For engagement rings, prioritise Cut → Colour (G–H) → Clarity (VS2+) → then maximise Carat within budget. Avoid the trap of buying a lower cut grade to get more carat weight.

Diamond Earrings
Earrings are viewed from 2–3 feet away — so grade priorities shift. Go for size (carat) and cut first; clarity can be SI1 eye-clean without any visible difference. Best daily-wear investment in fine jewellery.

Diamond Necklaces & Pendants
Versatile across ethnic and western wear. A solitaire pendant (0.20–0.50ct) is the most popular entry point. Look for a secure bail and a chain rated for the weight of the pendant.
Diamond Bracelets & Bangles
Tennis bracelets (line of matched diamonds) and diamond-set bangles are increasingly popular for gifting. Check the clasp — it carries the security load for the entire piece.
Natural vs Lab-Grown: Which Should You Buy?
Lab-grown diamonds are chemically identical to natural ones and cost 40–60% less. But they depreciate faster and haven't reached parity for Indian weddings and milestone gifting. Natural diamonds hold resale value better and carry the cultural weight most Indian buyers expect for significant purchases.

Why Certification and Hallmarking Matter
- IGI Certificate — verifies your diamond's 4C grades, independent of the seller. Report number on every My Carat product page.
- BIS Hallmark — India's government purity guarantee on gold. Every My Carat piece uses BIS-hallmarked 18kt or 22kt gold. Look for the BIS logo + purity stamp + assaying centre mark + year.

Understanding Price in India
Diamond jewellery price in India = diamond cost (USD-denominated, international market) + gold cost (live MCX rate) + making charges + GST. Both components fluctuate daily. My Carat's price calculator updates every day with live MCX gold rates — what you see is what the piece costs today.
