About this 0.67ct natural oval diamond

This 0.67ct natural oval sits in the half to three-quarter carat band, graded H 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 7556866017. Listed at 5 retailers as of October 31, 2026, with prices from $889 to $1,122, a $233 spread on the same certified stone. Blue Nile lists it at $1,122. 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.
