About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5566616416. Listed at 17 retailers as of November 5, 2026, with prices from HK$2,147 to HK$11,521, a HK$9,374 spread on the same certified stone. NZ Jewellers lists it at HK$11,521. 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.
