About this 0.9ct natural heart diamond

This 0.9ct 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 stated by the retailer rather than the lab and certified by GIA 6552554594. Listed at 16 retailers as of October 30, 2026, with prices from HK$7,579 to HK$23,075, a HK$15,496 spread on the same certified stone. NZ Jewellers lists it at HK$23,075. 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.
