About this 0.37ct lab-grown cushion diamond

This 0.37ct lab-grown cushion sits in the sub-half-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG821623684 or 821623684. Listed at 14 retailers as of October 25, 2026, with a 396% 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.
