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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 1243991686. Listed at 22 retailers as of November 1, 2026, with prices from HK$12,318 to HK$27,132, a HK$14,814 spread on the same certified stone. MOH London lists it at HK$27,132. 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.
