About this 0.64ct lab-grown cushion diamond

This 0.64ct lab-grown cushion sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG799608180 or 799608180. Listed at 19 retailers as of October 30, 2026, with prices from $523 to $4,436, a $3,912 spread on the same certified stone. Do Amore Diamonds lists it at $4,436. 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.
