About this 0.55ct natural heart diamond

This 0.55ct natural heart sits in the half to three-quarter carat band, graded G 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 7521619695. Listed at 5 retailers as of November 5, 2026, with prices from HK$3,394 to HK$4,554, a HK$1,160 spread on the same certified stone. Blue Nile lists it at HK$4,554. 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.
