This 0.49ct lab-grown oval sits in the sub-half-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG847690791 or 847690791. Listed at 7 retailers as of October 30, 2026, with prices from £96 to £254, a £158 spread on the same certified stone. Brilliant Earth lists it at £254. 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.
