About this 1.51ct lab-grown asscher diamond

This 1.51ct lab-grown asscher sits in the one-and-a-half to two carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG809651079 or 809651079. Listed at 21 retailers as of October 30, 2026, with a 397% 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.
