This 1.55ct natural round sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI 731521738. Listed at 7 retailers as of November 5, 2026, with prices from HK$29,882 to HK$39,195, a HK$9,312 spread on the same certified stone. Aurelinne lists it at HK$39,195. 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.
