About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6532091222. Listed at 16 retailers as of October 27, 2026, with prices from HK$4,339 to HK$14,750, a HK$10,411 spread on the same certified stone. NZ Jewellers lists it at HK$14,750. 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.
