About this 1.03ct lab-grown oval diamond

This 1.03ct lab-grown oval sits in the classic one-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG839644189 or 839644189. Listed at 22 retailers as of November 3, 2026, with prices from £130 to £970, a £841 spread on the same certified stone. Do Amore Diamonds lists it at £970. 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.
