About this 0.55ct natural heart diamond

This 0.55ct natural heart sits in the half to three-quarter carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6535133331. Listed at 3 retailers as of November 6, 2026, with prices from HK$3,668 to HK$4,565, a HK$897 spread on the same certified stone. 77 Diamonds lists it at HK$4,565. 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.
