About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6565197871. Listed at 13 retailers as of November 4, 2026, with prices from €2,446 to €4,464, a €2,018 spread on the same certified stone. Wholesale Diamonds Direct lists it at €4,464. 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.
