About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6542751079. Listed at 16 retailers as of October 29, 2026, with prices from HK$10,553 to HK$24,651, a HK$14,098 spread on the same certified stone. MOH London lists it at HK$24,651. 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.
