About this 0.73ct lab-grown cushion diamond

This 0.73ct 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 LG804603874 or 804603874. Listed at 13 retailers as of November 4, 2026, with prices from $687 to $4,518, a $3,832 spread on the same certified stone. Do Amore Diamonds lists it at $4,518. 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.
