About this 0.64ct natural heart diamond

This 0.64ct natural heart sits in the half to three-quarter carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7561334048. Listed at 2 retailers as of November 1, 2026, with prices from £408 to £473, a £65 spread on the same certified stone. 77 Diamonds lists it at £473. 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.
