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 standard cut grade stated by the retailer rather than the lab and certified by GIA 6551672027. Listed at 20 retailers as of October 28, 2026, with prices from HK$13,758 to HK$36,319, a HK$22,561 spread on the same certified stone. Queensmith lists it at HK$36,319. 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.
