About this 0.9ct natural cushion diamond

This 0.9ct natural cushion 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 6502303819. Listed at 17 retailers as of October 30, 2026, with prices from HK$12,111 to HK$35,612, a HK$23,501 spread on the same certified stone. NZ Jewellers lists it at HK$35,612. 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.
