About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2566089377. Listed at 13 retailers as of November 4, 2026, with prices from HK$8,065 to HK$18,852, a HK$10,787 spread on the same certified stone. MOH London lists it at HK$18,852. 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.
