This 1.55ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG677569932 or 677569932. Listed at 12 retailers as of November 3, 2026, with prices from HK$4,417 to HK$20,427, a HK$16,009 spread on the same certified stone. MOH London lists it at HK$20,427. 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.
