About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6561430129. Listed at 17 retailers as of October 30, 2026, with prices from $410 to $1,725, a $1,315 spread on the same certified stone. NZ Jewellers lists it at $1,725. 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.
