1-Carat Lab-Grown Diamond Price in India (2026): A Complete Cost Guide

Price Guide 2026

“How much is a 1-carat lab-grown diamond in India?” is one of the most-searched jewellery questions of 2026 — and the honest answer is: far less than it used to be. Here is what you can expect to pay this year, and exactly what moves the price.

Short answer: In 2026, a 1-carat loose lab-grown diamond in India starts from roughly ₹35,000–₹45,000 for good colour and clarity. A finished 1-carat ring (stone + setting) typically ranges from about ₹60,000 to ₹1,20,000+ depending on the metal and design.

Why lab-grown diamond prices have dropped

Lab-grown diamond prices in India are roughly 15–20% lower than 2023, and dramatically lower than five years ago. Better growing technology, more supply and wider acceptance have pushed prices down — great news for buyers, especially couples who now get a bigger, cleaner stone for the same budget.

How to get the best value

Buy factory-direct. Skipping retail mark-ups is the single biggest saving. Choose G–H VS — the sweet spot where the stone looks white and eye-clean without paying for grades you cannot see. Pick a round or oval for the most sparkle-per-rupee, and consider gold vermeil if you want the gold look at a fraction of solid-gold cost.
