About this 1.4ct lab-grown round diamond

This 1.4ct lab-grown round sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by IGI LG474115433 or 474115433. Listed at 11 retailers as of October 28, 2026, with a 135% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
