About this 0.85ct natural heart diamond

This 0.85ct natural heart sits in the just-under-one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 734506963. Listed at 12 retailers as of October 30, 2026, with prices from HK$6,057 to HK$19,144, a HK$13,087 spread on the same certified stone. NZ Jewellers lists it at HK$19,144. 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.
