About this 1.02ct lab-grown cushion diamond

This 1.02ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836620183 or 836620183. Listed at 16 retailers as of October 25, 2026, with prices from $289 to $1,650, a $1,361 spread on the same certified stone. Helzberg Diamonds lists it at $1,650. 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.
