About this 0.49ct lab-grown cushion diamond

This 0.49ct lab-grown cushion sits in the sub-half-carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG640492942 or 640492942. Listed at 8 retailers as of October 30, 2026, with a 147% 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.
