About this 3.09ct lab-grown cushion diamond

This 3.09ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG848666665 or 848666665. Listed at 11 retailers as of October 31, 2026, with prices from $1,090 to $6,476, a $5,386 spread on the same certified stone. Brilliant Earth lists it at $6,476. 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.
