About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2536781518. Listed at 13 retailers as of November 5, 2026, with prices from $792 to $2,694, a $1,902 spread on the same certified stone. NZ Jewellers lists it at $2,694. 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.
