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 SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6107574915. Listed at 2 retailers as of November 5, 2026, with prices from HK$5,024 to HK$7,176, a HK$2,152 spread on the same certified stone. 77 Diamonds lists it at HK$7,176. 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.
