About this 1ct natural heart diamond

This 1ct natural heart sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7543188396. Listed at 7 retailers as of November 6, 2026, with prices from HK$7,054 to HK$11,299, a HK$4,246 spread on the same certified stone. GemTrove lists it at HK$11,299. 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.
