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 G 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 2566597294. Listed at 13 retailers as of November 5, 2026, with prices from $6,289 to $11,144, a $4,855 spread on the same certified stone. Wholesale Diamonds Direct lists it at $11,144. 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.
