About this 1ct lab-grown oval diamond

This 1ct lab-grown oval sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by IGI LG526279600 or 526279600. Listed at 13 retailers as of October 31, 2026, with a 114% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
