This 1.27ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG566326676 or 566326676. Listed at 2 retailers as of November 1, 2026, with prices from £323 to £821, a £498 spread on the same certified stone. MOH London lists it at £821. 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.
