This 1.7ct 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 LG440013946 or 440013946. Listed at 10 retailers as of October 29, 2026, with prices from HK$7,532 to HK$36,259, a HK$28,727 spread on the same certified stone. MOH London lists it at HK$36,259. 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.
