About this 1.33ct lab-grown cushion diamond

This 1.33ct 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 standard cut grade and certified by IGI LG831696418 or 831696418. Listed at 19 retailers as of October 28, 2026, with prices from $485 to $3,003, a $2,519 spread on the same certified stone. Helzberg Diamonds lists it at $3,003. 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.
