About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded D 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 6551666431. Listed at 14 retailers as of November 5, 2026, with prices from ₹6,99,892 to ₹12,54,677, a ₹5,54,785 spread on the same certified stone. With Clarity lists it at ₹12,54,677. 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.
