About this 1.29ct natural marquise diamond

This 1.29ct natural marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2566597529. Listed at 14 retailers as of November 6, 2026, with prices from $6,303 to $11,241, a $4,938 spread on the same certified stone. Wholesale Diamonds Direct lists it at $11,241. 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.
