About this 0.7ct lab-grown radiant diamond

This 0.7ct lab-grown radiant 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 LG566394115 or 566394115. Listed at 18 retailers as of November 2, 2026, with prices from £95 to £909, a £814 spread on the same certified stone. Do Amore Diamonds lists it at £909. 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.
