About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6552531907. Listed at 15 retailers as of November 5, 2026, with prices from ₹50,435 to ₹1,86,525, a ₹1,36,090 spread on the same certified stone. NZ Jewellers lists it at ₹1,86,525. 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.
