About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6331458484. Listed at 19 retailers as of October 27, 2026, with prices from €6,593 to €14,788, a €8,195 spread on the same certified stone. NZ Jewellers lists it at €14,788. 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.
