This 4.01ct lab-grown asscher sits in the three to five carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG784627919 or 784627919. Listed at 12 retailers as of October 27, 2026, with prices from $418 to $1,698, a $1,280 spread on the same certified stone. Taylor and Hart lists it at $1,698. 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.
