This 3ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG523274986 or 523274986. Listed at 9 retailers as of October 29, 2026, with prices from HK$4,880 to HK$23,605, a HK$18,725 spread on the same certified stone. MOH London lists it at HK$23,605. 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.
