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 October 30, 2026, with prices from $260 to $1,720, a $1,460 spread on the same certified stone. Kay Jewelers lists it at $1,720. 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.
