This 4.78ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG722535802 or 722535802. Listed at 9 retailers as of October 30, 2026, with prices from $2,187 to $12,912, a $10,725 spread on the same certified stone. Do Amore Diamonds lists it at $12,912. 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.
