About this 0.55ct natural oval diamond

This 0.55ct natural oval sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1553924039. Listed at 4 retailers as of November 6, 2026, with prices from HK$4,138 to HK$5,952, a HK$1,814 spread on the same certified stone. Steven Stone lists it at HK$5,952. 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.
