About this 2.5ct natural marquise diamond

This 2.5ct natural marquise sits in the two to three carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6555740706. Listed at 4 retailers as of October 30, 2026, with prices from $34,919 to $42,253, a $7,334 spread on the same certified stone. Diamond Exchange Canada lists it at $42,253. 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.
