About this 1.4ct lab-grown cushion diamond

This 1.4ct 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 LG843612983 or 843612983. Listed at 12 retailers as of October 30, 2026, with prices from $733 to $3,353, a $2,619 spread on the same certified stone. Brilliant Earth lists it at $3,353. 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.
