This 1.5ct lab-grown round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG425067129 or 425067129. Listed at 10 retailers as of November 3, 2026, with prices from HK$6,668 to HK$35,898, a HK$29,230 spread on the same certified stone. MOH London lists it at HK$35,898. 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.
