About this 0.51ct natural round diamond

This 0.51ct natural round sits in the half to three-quarter carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by GIA 6315634053. Listed at 17 retailers as of November 4, 2026, with prices from HK$2,911 to HK$13,251, a HK$10,340 spread on the same certified stone. NZ Jewellers lists it at HK$13,251. 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.
