About this 1ct lab-grown cushion diamond

This 1ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG851619598 or 851619598. Listed at 5 retailers as of November 2, 2026, with prices from $262 to $430, a $168 spread on the same certified stone. Diamond Heaven lists it at $430. 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.
