About this 1.05ct natural cushion diamond

This 1.05ct natural cushion sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2547527944. Listed at 8 retailers as of November 2, 2026, with prices from HK$23,546 to HK$42,678, a HK$19,132 spread on the same certified stone. MOH London lists it at HK$42,678. 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.
