This 0.7ct lab-grown round sits in the half to three-quarter carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG459191337 or 459191337. Listed at 12 retailers as of November 5, 2026, with prices from £282 to £2,303, a £2,021 spread on the same certified stone. MOH London lists it at £2,303. 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.
