About this 0.7ct lab-grown cushion diamond

This 0.7ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG569304894 or 569304894. Listed at 4 retailers as of October 29, 2026, with prices from $421 to $550, a $129 spread on the same certified stone. Kay Jewelers lists it at $550. 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.
