About this 1.02ct lab-grown emerald diamond

This 1.02ct lab-grown emerald sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by IGI LG512204082 or 512204082. Listed at 12 retailers as of November 4, 2026, with a 196% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
