About this 0.9ct lab-grown oval diamond

This 0.9ct lab-grown oval sits in the just-under-one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by IGI LG447000981 or 447000981. Listed at 10 retailers as of October 31, 2026, with a 327% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
