About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6462181862. Listed at 10 retailers as of November 4, 2026, with prices from ₹2,75,280 to ₹5,90,070, a ₹3,14,791 spread on the same certified stone. MOH London lists it at ₹5,90,070. 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.
