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 1549378687. Listed at 21 retailers as of November 3, 2026, with prices from HK$9,530 to HK$21,430, a HK$11,900 spread on the same certified stone. MOH London lists it at HK$21,430. 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.
