About this 1.02ct lab-grown asscher diamond

This 1.02ct lab-grown asscher sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG474106644 or 474106644. Listed at 15 retailers as of November 2, 2026, with a 322% 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.
