About this 0.74ct lab-grown cushion diamond

This 0.74ct 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 LG816662564 or 816662564. Listed at 13 retailers as of November 2, 2026, with prices from $428 to $2,515, a $2,087 spread on the same certified stone. Diamond Exchange Canada lists it at $2,515. 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.
