About this 0.51ct natural heart diamond

This 0.51ct 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 6532425710. Listed at 4 retailers as of November 6, 2026, with prices from HK$3,253 to HK$4,159, a HK$907 spread on the same certified stone. 77 Diamonds lists it at HK$4,159. 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.
