This 1.5ct lab-grown round sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG425067155 or 425067155. Listed at 11 retailers as of November 5, 2026, with prices from HK$10,199 to HK$41,209, a HK$31,010 spread on the same certified stone. MOH London lists it at HK$41,209. 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.
