This 3.01ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG840657033 or 840657033. Listed at 11 retailers as of November 6, 2026, with prices from HK$2,955 to HK$20,142, a HK$17,187 spread on the same certified stone. Brilliant Earth lists it at HK$20,142. 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.
