About this 2.5ct natural oval diamond

This 2.5ct natural oval sits in the two to three carat band, graded J 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 6555983666. Listed at 11 retailers as of October 31, 2026, with prices from $11,879 to $22,743, a $10,865 spread on the same certified stone. With Clarity lists it at $22,743. 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.
