About this 2.57ct lab-grown oval diamond

This 2.57ct lab-grown oval sits in the two to three carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG843644919 or 843644919. Listed at 23 retailers as of October 26, 2026, with a 365% 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.
