Lab Grown Diamond Prices by Carat, Cut and Quality
Lab grown diamonds cost 50-70% less than mined stones. Understand how price is built up so you get the best value for your budget.
How Lab Grown Pricing Works
A lab grown diamond price depends on the same 4Cs as a mined stone, but the base cost is dramatically lower. At TONGLIN we price each piece based on silver weight, gold type and stone size. See our rings.

Where to Save and Where to Splurge
Save on clarity (SI1 is eye-clean in most shapes) and colour (J looks white in yellow gold). Splurge on cut — a well-cut 1ct stone out-sparkles a poorly cut 2ct. Get a custom quote.
