This 1.28ct lab-grown asscher sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG795652181 or 795652181. Listed at 6 retailers as of November 1, 2026, with prices from £296 to £781, a £485 spread on the same certified stone. MOH London lists it at £781. 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.
