About this 1.42ct lab-grown asscher diamond

This 1.42ct lab-grown asscher sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG728522978 or 728522978. Listed at 9 retailers as of November 2, 2026, with prices from HK$4,420 to HK$10,690, a HK$6,270 spread on the same certified stone. MOH London lists it at HK$10,690. 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.
