About this 2.51ct natural marquise diamond

This 2.51ct natural marquise sits in the two to three carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1553744455. Listed at 25 retailers as of October 26, 2026, with prices from ₹20,37,768 to ₹33,70,996, a ₹13,33,227 spread on the same certified stone. MOH London lists it at ₹33,70,996. 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.
