About this 3ct lab-grown heart diamond

This 3ct lab-grown heart sits in the three to five carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by IGI LG674515106 or 674515106. Listed at 13 retailers as of October 31, 2026, with a 39% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
