About this 1ct natural heart diamond

This 1ct natural heart sits in the classic one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2546236726. Listed at 13 retailers as of November 5, 2026, with prices from $1,346 to $4,411, a $3,065 spread on the same certified stone. NZ Jewellers lists it at $4,411. 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.
