About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5546026615. Listed at 15 retailers as of November 5, 2026, with prices from £331 to £1,417, a £1,086 spread on the same certified stone. NZ Jewellers lists it at £1,417. 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.
