About this 3.03ct natural heart diamond

This 3.03ct natural heart sits in the three to five 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 6542825428. Listed at 17 retailers as of November 5, 2026, with prices from $20,175 to $38,418, a $18,243 spread on the same certified stone. With Clarity lists it at $38,418. 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.
