About this 1.7ct lab-grown oval diamond

This 1.7ct lab-grown oval sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by IGI LG506191341 or 506191341. Listed at 12 retailers as of October 30, 2026, with a 199% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
