About this 0.51ct natural heart diamond

This 0.51ct natural heart sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5543163685. Listed at 10 retailers as of November 6, 2026, with prices from HK$3,770 to HK$7,908, a HK$4,138 spread on the same certified stone. 77 Diamonds lists it at HK$7,908. 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.
