About this 0.91ct natural heart diamond

This 0.91ct natural heart sits in the just-under-one-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 2161621941. Listed at 8 retailers as of October 27, 2026, with prices from £1,422 to £2,521, a £1,099 spread on the same certified stone. Wholesale Diamonds Direct lists it at £2,521. 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.
