About this 0.51ct natural princess diamond

This 0.51ct natural princess sits in the half to three-quarter carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2566275987. Listed at 2 retailers as of November 2, 2026, with prices from HK$2,626 to HK$3,566, a HK$940 spread on the same certified stone. 77 Diamonds lists it at HK$3,566. 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.
