About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1439777400. Listed at 16 retailers as of November 4, 2026, with prices from ₹2,52,457 to ₹5,75,041, a ₹3,22,584 spread on the same certified stone. MOH London lists it at ₹5,75,041. 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.
