About this 1.4ct natural heart diamond

This 1.4ct 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 2537983729. Listed at 16 retailers as of November 5, 2026, with prices from $4,918 to $11,565, a $6,647 spread on the same certified stone. NZ Jewellers lists it at $11,565. 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.
