This 1.71ct lab-grown heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG436044977 or 436044977. Listed at 5 retailers as of November 3, 2026, with prices from HK$3,300 to HK$14,333, a HK$11,033 spread on the same certified stone. MOH London lists it at HK$14,333. 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.
