About this 3.1ct lab-grown cushion diamond

This 3.1ct lab-grown cushion 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 LG784688760 or 784688760. Listed at 13 retailers as of October 28, 2026, with prices from $746 to $3,092, a $2,346 spread on the same certified stone. Brilliance lists it at $3,092. 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.
