About this 0.51ct natural princess diamond

This 0.51ct natural princess sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1565219935. Listed at 3 retailers as of October 31, 2026, with prices from HK$3,605 to HK$4,465, a HK$860 spread on the same certified stone. 77 Diamonds lists it at HK$4,465. 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.
