About this 0.81ct natural oval diamond

This 0.81ct natural oval sits in the just-under-one-carat band, graded J 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 5566440785. Listed at 9 retailers as of October 30, 2026, with prices from HK$5,406 to HK$18,728, a HK$13,322 spread on the same certified stone. NZ Jewellers lists it at HK$18,728. 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.
