This 0.51ct lab-grown cushion sits in the half to three-quarter carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG436073164 or 436073164. Listed at 6 retailers as of November 1, 2026, with prices from HK$2,273 to HK$11,884, a HK$9,612 spread on the same certified stone. MOH London lists it at HK$11,884. 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.
