About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6542691720. Listed at 7 retailers as of November 1, 2026, with prices from HK$2,310 to HK$4,783, a HK$2,473 spread on the same certified stone. 77 Diamonds lists it at HK$4,783. 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.
