About this 1.01ct natural cushion diamond

This 1.01ct natural cushion sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6372936927. Listed at 19 retailers as of November 6, 2026, with prices from HK$15,557 to HK$23,990, a HK$8,433 spread on the same certified stone. Washington Diamond lists it at HK$23,990. 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.
