About this 1ct natural heart diamond

This 1ct natural heart sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6521239587. Listed at 26 retailers as of November 5, 2026, with prices from HK$13,653 to HK$36,130, a HK$22,478 spread on the same certified stone. NZ Jewellers lists it at HK$36,130. 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.
