About this 2.57ct lab-grown asscher diamond

This 2.57ct lab-grown asscher sits in the two to three carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG801680814 or 801680814. Listed at 5 retailers as of October 28, 2026, with a 44% 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.
