About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded D colour (colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2506268781. Listed at 4 retailers as of November 6, 2026, with prices from HK$11,035 to HK$20,260, a HK$9,225 spread on the same certified stone. Yorxs lists it at HK$20,260. 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.
