About this 1.53ct lab-grown cushion diamond

This 1.53ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG653434162 or 653434162. Listed at 19 retailers as of October 29, 2026, with a 695% 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.
