About this 0.5ct natural round diamond

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 1289573368. Listed at 22 retailers as of October 30, 2026, with prices from HK$3,264 to HK$14,773, a HK$11,510 spread on the same certified stone. NZ Jewellers lists it at HK$14,773. 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.
