About this 1.73ct lab-grown cushion diamond

This 1.73ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG732514656 or 732514656. Listed at 16 retailers as of October 28, 2026, with a 347% 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.
