About this 0.51ct natural princess diamond

This 0.51ct natural princess sits in the half to three-quarter carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7566305581. Listed at 4 retailers as of November 4, 2026, with prices from HK$3,609 to HK$4,530, a HK$921 spread on the same certified stone. 77 Diamonds lists it at HK$4,530. 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.
