About this 0.91ct natural heart diamond

This 0.91ct natural heart sits in the just-under-one-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 HRD 180000100222. Listed at 3 retailers as of November 1, 2026, with prices from HK$21,225 to HK$34,386, a HK$13,161 spread on the same certified stone. MOH London lists it at HK$34,386. 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.
