About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-carat band, graded K colour (faint-tinted) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6442780479. Listed at 6 retailers as of November 2, 2026, with prices from HK$18,300 to HK$33,344, a HK$15,044 spread on the same certified stone. MOH London lists it at HK$33,344. 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.
