This 1.58ct lab-grown asscher sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG700517940 or 700517940. Listed at 13 retailers as of November 3, 2026, with prices from £198 to £2,126, a £1,928 spread on the same certified stone. MOH London lists it at £2,126. 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.
