This 3.78ct 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 LG801608304 or 801608304. Listed at 9 retailers as of October 30, 2026, with prices from $2,521 to $12,470, a $9,949 spread on the same certified stone. Diamonds Direct lists it at $12,470. 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.
