About this 0.81ct natural heart diamond

This 0.81ct natural heart sits in the just-under-one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1275345411. Listed at 5 retailers as of October 29, 2026, with prices from £808 to £1,912, a £1,104 spread on the same certified stone. MOH London lists it at £1,912. 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.
