This 0.73ct lab-grown round sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG816670166 or 816670166. Listed at 9 retailers as of October 29, 2026, with prices from £161 to £932, a £771 spread on the same certified stone. Reve Diamonds lists it at £932. 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.
