About this 1.17ct lab-grown oval diamond

This 1.17ct 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 LG851604879 or 851604879. Listed at 15 retailers as of November 4, 2026, with prices from £156 to £890, a £733 spread on the same certified stone. Reve Diamonds lists it at £890. 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.
