About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded H colour (near-colourless) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6485119251. Listed at 7 retailers as of October 31, 2026, with prices from HK$4,519 to HK$6,829, a HK$2,310 spread on the same certified stone. Yorxs lists it at HK$6,829. 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.
