This 0.5ct natural round sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by GIA 6495450286. Listed at 24 retailers as of October 30, 2026, with prices from HK$2,912 to HK$14,240, a HK$11,328 spread on the same certified stone. NZ Jewellers lists it at HK$14,240. 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.
