This 1.72ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG605341890 or 605341890. Listed at 9 retailers as of October 30, 2026, with prices from £345 to £1,597, a £1,252 spread on the same certified stone. Do Amore Diamonds lists it at £1,597. 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.
