About this 0.75ct natural heart diamond

This 0.75ct natural heart sits in the just-under-one-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 1343078046. Listed at 15 retailers as of November 5, 2026, with prices from £535 to £2,243, a £1,708 spread on the same certified stone. NZ Jewellers lists it at £2,243. 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.
