About this 4.52ct lab-grown cushion diamond

This 4.52ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG782633553 or 782633553. Listed at 18 retailers as of October 31, 2026, with prices from $1,712 to $12,260, a $10,548 spread on the same certified stone. Brilliant Earth lists it at $12,260. 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.
