About this 4.01ct lab-grown asscher diamond

This 4.01ct lab-grown asscher sits in the three to five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG811691442 or 811691442. Listed at 23 retailers as of October 30, 2026, with a 596% 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.
