This 1.75ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG816608070 or 816608070. Listed at 13 retailers as of November 1, 2026, with prices from HK$3,029 to HK$13,113, a HK$10,085 spread on the same certified stone. MOH London lists it at HK$13,113. 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.
