About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6392602089. Listed at 5 retailers as of November 4, 2026, with prices from ₹92,981 to ₹1,74,027, a ₹81,046 spread on the same certified stone. MOH London lists it at ₹1,74,027. 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.
