About this 0.51ct natural radiant diamond

This 0.51ct natural radiant sits in the half to three-quarter carat band, graded J 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 2436054002. Listed at 21 retailers as of October 29, 2026, with prices from HK$5,516 to HK$12,147, a HK$6,631 spread on the same certified stone. MOH London lists it at HK$12,147. 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.
