About this 1.5ct natural oval diamond

This 1.5ct natural oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6515777659. Listed at 23 retailers as of October 27, 2026, with prices from £6,050 to £10,771, a £4,720 spread on the same certified stone. NZ Jewellers lists it at £10,771. 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.
