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 2245009522. Listed at 11 retailers as of November 4, 2026, with prices from HK$15,792 to HK$30,547, a HK$14,755 spread on the same certified stone. MOH London lists it at HK$30,547. 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.
