About this 1.38ct lab-grown cushion diamond

This 1.38ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840629940 or 840629940. Listed at 8 retailers as of October 30, 2026, with prices from $1,095 to $3,640, a $2,545 spread on the same certified stone. Helzberg Diamonds lists it at $3,640. 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.
