About this 0.57ct natural radiant diamond

This 0.57ct natural radiant sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1509350892. Listed at 2 retailers as of November 1, 2026, with prices from HK$4,747 to HK$6,002, a HK$1,255 spread on the same certified stone. 77 Diamonds lists it at HK$6,002. 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.
