About this 0.9ct natural oval diamond

This 0.9ct natural oval sits in the just-under-one-carat band, graded I 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 1557335700. Listed at 22 retailers as of October 30, 2026, with prices from HK$13,260 to HK$33,942, a HK$20,682 spread on the same certified stone. NZ Jewellers lists it at HK$33,942. 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.
