About this 0.5ct lab-grown oval diamond

This 0.5ct lab-grown oval sits in the half to three-quarter carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG778617273 or 778617273. Listed at 21 retailers as of November 3, 2026, with prices from £147 to £963, a £816 spread on the same certified stone. Kay Jewelers lists it at £963. 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.
