About this 3.87ct lab-grown asscher diamond

This 3.87ct lab-grown asscher sits in the three to five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG652431263 or 652431263. Listed at 11 retailers as of October 31, 2026, with a 692% 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.
