About this 1.31ct natural heart diamond

This 1.31ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6455351791. Listed at 5 retailers as of November 4, 2026, with prices from $3,358 to $6,094, a $2,736 spread on the same certified stone. MOH London lists it at $6,094. 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.
