About this 1.71ct natural oval diamond

This 1.71ct natural oval sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 13 retailers as of November 5, 2026, with prices from £3,772 to £8,368, a £4,595 spread on the same certified stone. NZ Jewellers lists it at £8,368. 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.
