About this 3ct natural marquise diamond

This 3ct natural marquise sits in the three to five 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 1565578534. Listed at 14 retailers as of November 5, 2026, with prices from $58,331 to $94,001, a $35,670 spread on the same certified stone. Helzberg Diamonds lists it at $94,001. 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.
