About this 0.74ct lab-grown cushion diamond

This 0.74ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG749586275 or 749586275. Listed at 10 retailers as of October 27, 2026, with prices from £185 to £900, a £715 spread on the same certified stone. Queensmith lists it at £900. 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.
