About this 1.03ct natural heart diamond

This 1.03ct natural heart sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2173463647. Listed at 3 retailers as of November 6, 2026, with prices from $2,259 to $3,412, a $1,153 spread on the same certified stone. 77 Diamonds lists it at $3,412. 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.
