About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-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 1146870344. Listed at 7 retailers as of November 4, 2026, with prices from ₹1,61,167 to ₹3,41,136, a ₹1,79,970 spread on the same certified stone. MOH London lists it at ₹3,41,136. 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.
