About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3515964985. Listed at 14 retailers as of November 5, 2026, with prices from HK$4,146 to HK$10,667, a HK$6,521 spread on the same certified stone. Adiamor lists it at HK$10,667. 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.
