About this 3ct natural marquise diamond

This 3ct natural marquise sits in the three to five 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. Listed at 10 retailers as of October 27, 2026, with prices from €25,439 to €31,547, a €6,108 spread on the same certified stone. The Diamond Guys lists it at €31,547. 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.
