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 SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1555020554. Listed at 8 retailers as of October 30, 2026, with prices from ₹6,48,176 to ₹8,28,653, a ₹1,80,477 spread on the same certified stone. Diamond Exchange Canada lists it at ₹8,28,653. 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.
