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 very-good cut grade stated by the retailer rather than the lab and certified by HRD 15036210025. Listed at 2 retailers as of October 31, 2026, with prices from HK$5,025 to HK$7,613, a HK$2,587 spread on the same certified stone. MOH London lists it at HK$7,613. 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.
