About this 4ct lab-grown asscher diamond

This 4ct 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 LG837646788 or 837646788. Listed at 14 retailers as of October 29, 2026, with prices from $1,505 to $16,004, a $14,500 spread on the same certified stone. Brilliant Earth lists it at $16,004. 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.
