About this 1.35ct lab-grown oval diamond

This 1.35ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by IGI LG440013851 or 440013851. Listed at 11 retailers as of October 31, 2026, with a 227% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
