About this 0.51ct natural oval diamond
This 0.51ct natural oval sits in the half to three-quarter carat band, graded H 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 HRD 260000137700. Listed at 11 retailers as of November 2, 2026, with prices from $395 to $1,630, a $1,235 spread on the same certified stone. NZ Jewellers lists it at $1,630. 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.
