About this 0.51ct natural princess diamond

This 0.51ct natural princess sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7518159445. Listed at 6 retailers as of November 4, 2026, with prices from HK$3,750 to HK$5,015, a HK$1,265 spread on the same certified stone. 77 Diamonds lists it at HK$5,015. 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.
