About this 2.5ct natural oval diamond

This 2.5ct natural oval sits in the two to three carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2428217538. Listed at 8 retailers as of October 28, 2026, with prices from $16,725 to $21,260, a $4,535 spread on the same certified stone. GemTrove lists it at $21,260. 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.
