About this 1ct lab-grown oval diamond

This 1ct lab-grown oval sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG843623104 or 843623104. Listed at 15 retailers as of October 30, 2026, with prices from £131 to £787, a £656 spread on the same certified stone. Reve Diamonds lists it at £787. 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.
