About this 1.01ct lab-grown oval diamond

This 1.01ct lab-grown oval sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG844668851 or 844668851. Listed at 16 retailers as of November 3, 2026, with prices from £140 to £813, a £673 spread on the same certified stone. Reve Diamonds lists it at £813. 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.
