About this 1.6ct lab-grown oval diamond

This 1.6ct lab-grown oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by IGI. Listed at 20 retailers as of October 24, 2026, with a 299% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
