About this 1.02ct natural heart diamond

This 1.02ct natural heart sits in the classic one-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 GIA 6551373645. Listed at 13 retailers as of November 2, 2026, with prices from HK$9,828 to HK$22,097, a HK$12,269 spread on the same certified stone. MOH London lists it at HK$22,097. 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.
