About this 1.35ct natural heart diamond

This 1.35ct natural heart sits in the one-and-a-quarter to one-and-a-half 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 2141933465. Listed at 3 retailers as of November 6, 2026, with prices from $4,392 to $6,440, a $2,047 spread on the same certified stone. 77 Diamonds lists it at $6,440. 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.
