About this 1.05ct natural cushion diamond

This 1.05ct natural cushion sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6502537243. Listed at 2 retailers as of October 30, 2026, with prices from €4,075 to €6,151, a €2,076 spread on the same certified stone. Diamond Quarter lists it at €6,151. 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.
