About this 0.3ct natural marquise diamond

This 0.3ct natural marquise sits in the sub-half-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5556848684. Listed at 2 retailers as of November 2, 2026, with prices from €185 to €266, a €81 spread on the same certified stone. 77 Diamonds lists it at €266. 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.
