About this 0.9ct natural heart diamond

This 0.9ct 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 2427248531. Listed at 11 retailers as of November 5, 2026, with prices from £1,030 to £2,511, a £1,482 spread on the same certified stone. NZ Jewellers lists it at £2,511. 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.
