This 1.77ct lab-grown asscher sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG728521685 or 728521685. Listed at 9 retailers as of October 29, 2026, with prices from £430 to £1,100, a £670 spread on the same certified stone. MOH London lists it at £1,100. 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.
