About this 0.81ct natural oval diamond

This 0.81ct natural oval sits in the just-under-one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2566428311. Listed at 5 retailers as of October 28, 2026, with prices from $1,515 to $1,904, a $389 spread on the same certified stone. Blue Nile lists it at $1,904. 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.
