About this 0.53ct lab-grown cushion diamond

This 0.53ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG816658268 or 816658268. Listed at 14 retailers as of November 3, 2026, with prices from $459 to $3,051, a $2,592 spread on the same certified stone. Kay Jewelers lists it at $3,051. 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.
