About this 0.5ct lab-grown cushion diamond

This 0.5ct lab-grown cushion sits in the half to three-quarter carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG853604248 or 853604248. Listed at 4 retailers as of November 1, 2026, with prices from $245 to $619, a $374 spread on the same certified stone. Taylor and Hart lists it at $619. 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.
