About this 1.91ct lab-grown asscher diamond

This 1.91ct lab-grown asscher sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG717507868 or 717507868. Listed at 19 retailers as of October 29, 2026, with a 399% 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.
