About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2567141174. Listed at 13 retailers as of November 4, 2026, with prices from $17,602 to $30,165, a $12,563 spread on the same certified stone. MOH London lists it at $30,165. 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.
