This 1.51ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by GIA 6531260924. Listed at 19 retailers as of November 1, 2026, with prices from HK$26,112 to HK$61,537, a HK$35,425 spread on the same certified stone. NZ Jewellers lists it at HK$61,537. 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.
