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 standard cut grade stated by the retailer rather than the lab and certified by GIA 5182242000. Listed at 2 retailers as of November 4, 2026, with prices from $1,936 to $3,455, a $1,519 spread on the same certified stone. MOH London lists it at $3,455. 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.
