About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6552657128. Listed at 13 retailers as of October 30, 2026, with prices from ₹7,45,701 to ₹13,36,421, a ₹5,90,720 spread on the same certified stone. With Clarity lists it at ₹13,36,421. 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.
