About this 0.53ct lab-grown cushion diamond

This 0.53ct 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 LG571304373 or 571304373. Listed at 4 retailers as of November 1, 2026, with a relatively tight 6% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
