This 1.83ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG515227078 or 515227078. Listed at 11 retailers as of November 1, 2026, with prices from HK$4,229 to HK$20,243, a HK$16,014 spread on the same certified stone. Do Amore Diamonds lists it at HK$20,243. 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.
