About this 0.45ct natural marquise diamond

This 0.45ct natural marquise sits in the sub-half-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556925719. Listed at 3 retailers as of November 4, 2026, with prices from $449 to $557, a $108 spread on the same certified stone. 77 Diamonds lists it at $557. 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.
