About this 0.51ct lab-grown cushion diamond

This 0.51ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG778616981 or 778616981. Listed at 18 retailers as of November 3, 2026, with prices from $321 to $2,671, a $2,350 spread on the same certified stone. Do Amore Diamonds lists it at $2,671. 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.
