About this 1ct natural heart diamond

This 1ct natural heart sits in the classic one-carat band, graded J colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 646466607. Listed at 12 retailers as of November 5, 2026, with prices from HK$13,574 to HK$34,351, a HK$20,777 spread on the same certified stone. NZ Jewellers lists it at HK$34,351. 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.
