About this 1.05ct lab-grown oval diamond

This 1.05ct lab-grown oval sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG772661684 or 772661684. Listed at 24 retailers as of October 29, 2026, with prices from £256 to £2,045, a £1,789 spread on the same certified stone. Brilliant Earth lists it at £2,045. 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.
