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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1563743349. Listed at 9 retailers as of November 4, 2026, with prices from £610 to £1,012, a £402 spread on the same certified stone. Wholesale Diamonds Direct lists it at £1,012. 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.
