About this 0.9ct natural oval diamond

This 0.9ct natural oval sits in the just-under-one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6421971558. Listed at 18 retailers as of October 31, 2026, with prices from €1,129 to €3,495, a €2,367 spread on the same certified stone. Moon Ocean lists it at €3,495. 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.
