About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-carat band, graded I 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 170002949845. Listed at 4 retailers as of November 4, 2026, with prices from HK$23,301 to HK$43,407, a HK$20,107 spread on the same certified stone. MOH London lists it at HK$43,407. 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.
