Diamonds and gemstones, without the marketing

CaratWire exists because almost all jewelry writing online is either retailer copy dressed up as editorial or thin explainers that stop right where the useful information begins. We write for the buyer who already knows a princess cut from a cushion and now wants to understand why two GIA-graded G/VS1 stones can differ by 30% in price, or whether a Mozambican ruby with minor heat treatment is fair at roughly $4,000–$5,000 per carat.

We cite GIA, AGS, IGI, SSEF, Gübelin, GRS, and AGL reports by name. We name countries of origin and treatment disclosures. We publish real retail and secondary-market price ranges, and we say plainly what holds value and what does not. The name is the idea: a carat is the unit of what a stone is worth, and a wire is a direct line to the facts behind the price.

CaratWire earns affiliate commission from a small number of vetted retailers, disclosed on the pages where it applies. We do not accept payment for editorial placement, and our grading and pricing assessments are written before any commercial relationship is considered. Find an error in a grading explanation or a stale price range? Tell us and we will correct it on the record.
