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 J 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 2556042660. Listed at 14 retailers as of November 4, 2026, with prices from €3,225 to €6,812, a €3,587 spread on the same certified stone. MOH London lists it at €6,812. 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.
