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 VS2 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2566439721. Listed at 22 retailers as of October 30, 2026, with prices from $1,020 to $4,286, a $3,266 spread on the same certified stone. NZ Jewellers lists it at $4,286. 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.
