About this 0.82ct lab-grown oval diamond

This 0.82ct lab-grown oval sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by IGI LG499190448 or 499190448. Listed at 13 retailers as of October 29, 2026, with a 101% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
