About this 1.28ct lab-grown oval diamond

This 1.28ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG823643905 or 823643905. Listed at 13 retailers as of October 26, 2026, with a 323% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
