About this 1.26ct lab-grown cushion diamond

This 1.26ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840622306 or 840622306. Listed at 16 retailers as of November 4, 2026, with prices from $660 to $3,637, a $2,977 spread on the same certified stone. Helzberg Diamonds lists it at $3,637. 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.
