This 1.55ct lab-grown asscher sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG728521715 or 728521715. Listed at 8 retailers as of November 1, 2026, with prices from £400 to £1,014, a £613 spread on the same certified stone. MOH London lists it at £1,014. 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.
