About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6555854230. Listed at 18 retailers as of October 30, 2026, with prices from ₹6,49,659 to ₹14,20,423, a ₹7,70,764 spread on the same certified stone. NZ Jewellers lists it at ₹14,20,423. 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.
