This 0.91ct lab-grown round sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG483125237 or 483125237. Listed at 19 retailers as of October 26, 2026, with prices from £156 to £916, a £760 spread on the same certified stone. Reve Diamonds lists it at £916. 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.
