About this 0.99ct lab-grown oval diamond

This 0.99ct lab-grown oval sits in the just-under-one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG642405852 or 642405852. Listed at 22 retailers as of October 29, 2026, with prices from £123 to £801, a £678 spread on the same certified stone. Flawless Fine Jewelry lists it at £801. 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.
