About this 0.51ct natural princess diamond

This 0.51ct natural princess sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 9 retailers as of November 5, 2026, with prices from HK$4,420 to HK$5,737, a HK$1,317 spread on the same certified stone. B2C Jewels lists it at HK$5,737. 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.
