About this 1ct natural round diamond

This 1ct natural round sits in the classic one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by GIA 1337283683. Listed at 22 retailers as of October 30, 2026, with prices from €2,031 to €5,598, a €3,567 spread on the same certified stone. NZ Jewellers lists it at €5,598. 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.
