About this 0.46ct natural heart diamond

This 0.46ct natural heart sits in the sub-half-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 5566293749. Listed at 3 retailers as of November 6, 2026, with prices from £285 to £349, a £64 spread on the same certified stone. 77 Diamonds lists it at £349. 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.
