About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1517519211. Listed at 14 retailers as of October 27, 2026, with prices from £3,681 to £7,060, a £3,379 spread on the same certified stone. NZ Jewellers lists it at £7,060. 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.
