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 LG577393199 or 577393199. Listed at 12 retailers as of October 26, 2026, with a 470% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
