This 3.01ct lab-grown cushion sits in the three to five carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG445061807 or 445061807. Listed at 6 retailers as of November 5, 2026, with prices from HK$15,518 to HK$91,293, a HK$75,775 spread on the same certified stone. MOH London lists it at HK$91,293. 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.
