Jewellery listings can look like a wall of letters and numbers — but once you know how to read them, they become the most useful tool you have for buying online with confidence. This guide breaks down every part of a jewellery product specifications table: carat weight, cut, color, clarity, metal purity, certification, and total carat weight (TCW), explained in plain terms with no jargon left unexplained. You’ll learn exactly what to check first, what red flags to watch for, and why photos alone should never be trusted over the actual specs. Whether you’re comparing a classic setting or browsing halo rings for women, or getting ready to buy an engagement ring online, this guide turns a confusing spec sheet into a clear, confident decision.
