About this 3.02ct lab-grown cushion diamond

This 3.02ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG841603650 or 841603650. Listed at 5 retailers as of November 4, 2026, with prices from $2,511 to $8,081, a $5,570 spread on the same certified stone. Brilliant Earth lists it at $8,081. 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.
