About this 1.3ct lab-grown cushion diamond

This 1.3ct 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 LG845699646 or 845699646. Listed at 11 retailers as of October 26, 2026, with prices from $645 to $3,113, a $2,468 spread on the same certified stone. MOH London lists it at $3,113. 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.
