About this 1.29ct lab-grown cushion diamond

This 1.29ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG651441778 or 651441778. Listed at 15 retailers as of November 4, 2026, with a 389% 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.
