About this 3.97ct lab-grown asscher diamond

This 3.97ct lab-grown asscher sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG637445622 or 637445622. Listed at 11 retailers as of November 1, 2026, with a 85% 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.
