This 1.26ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG651433909 or 651433909. Listed at 2 retailers as of November 4, 2026, with prices from £399 to £1,185, a £787 spread on the same certified stone. MOH London lists it at £1,185. 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.
