About this 0.66ct natural oval diamond

This 0.66ct natural oval sits in the half to three-quarter carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1559970684. Listed at 4 retailers as of October 31, 2026, with prices from HK$5,076 to HK$7,360, a HK$2,284 spread on the same certified stone. DreamStone lists it at HK$7,360. 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.
