This 1.67ct lab-grown round 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 LG754510366 or 754510366. Listed at 14 retailers as of November 1, 2026, with prices from HK$1,561 to HK$12,005, a HK$10,443 spread on the same certified stone. Brilliant Earth lists it at HK$12,005. 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.
