This 1.49ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG830620575 or 830620575. Listed at 14 retailers as of October 30, 2026, with prices from £243 to £1,465, a £1,222 spread on the same certified stone. Helzberg Diamonds lists it at £1,465. 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.
