About this 1.48ct lab-grown cushion diamond

This 1.48ct 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 LG623480662 or 623480662. Listed at 16 retailers as of October 30, 2026, with a 408% 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.
