About this 1.45ct natural heart diamond

This 1.45ct natural heart sits in the one-and-a-quarter to one-and-a-half 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 2225382695. Listed at 3 retailers as of November 6, 2026, with prices from £3,003 to £4,214, a £1,212 spread on the same certified stone. 77 Diamonds lists it at £4,214. 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.
