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 standard cut grade and certified by IGI LG684503810 or 684503810. Listed at 15 retailers as of October 29, 2026, with prices from $171 to $999, a $828 spread on the same certified stone. MOH London lists it at $999. 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.
