About this 1.14ct lab-grown oval diamond

This 1.14ct 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 LG842631018 or 842631018. Listed at 4 retailers as of November 6, 2026, with prices from £230 to £630, a £400 spread on the same certified stone. Frank Darling lists it at £630. 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.
