About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2506745477. Listed at 22 retailers as of November 5, 2026, with prices from €2,045 to €5,224, a €3,180 spread on the same certified stone. NZ Jewellers lists it at €5,224. 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.
