About this 0.45ct natural marquise diamond

This 0.45ct natural marquise sits in the sub-half-carat band, graded G colour (near-colourless) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2131906756. Listed at 2 retailers as of October 29, 2026, with prices from $514 to $788, a $274 spread on the same certified stone. Yorxs lists it at $788. 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.
