This 1.2ct lab-grown round sits in the classic one-carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a top-tier cut grade and certified by IGI LG492113522 or 492113522. Listed at 12 retailers as of November 4, 2026, with a 179% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
