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 standard cut grade stated by the retailer rather than the lab and certified by GIA 7563622122. Listed at 14 retailers as of November 5, 2026, with prices from £1,755 to £4,049, a £2,294 spread on the same certified stone. NZ Jewellers lists it at £4,049. 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.
