About this 1.5ct natural oval diamond

This 1.5ct natural oval sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1479484370. Listed at 14 retailers as of November 5, 2026, with prices from £1,798 to £4,220, a £2,422 spread on the same certified stone. NZ Jewellers lists it at £4,220. 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.
