About this 1.2ct lab-grown round diamond

This 1.2ct lab-grown round sits in the classic one-carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a top-tier cut grade and certified by IGI LG440013278 or 440013278. Listed at 14 retailers as of October 29, 2026, with a 177% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
