This 1.73ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG841674991 or 841674991. Listed at 11 retailers as of October 28, 2026, with prices from £226 to £1,063, a £837 spread on the same certified stone. Reve Diamonds lists it at £1,063. 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.
