About this 1.48ct lab-grown cushion diamond

This 1.48ct 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 LG836612030 or 836612030. Listed at 15 retailers as of October 30, 2026, with prices from $827 to $4,209, a $3,383 spread on the same certified stone. Brilliant Earth lists it at $4,209. 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.
