About this 0.77ct natural heart diamond

This 0.77ct natural heart sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5211475835. Listed at 2 retailers as of November 6, 2026, with prices from £965 to £1,476, a £511 spread on the same certified stone. 77 Diamonds lists it at £1,476. 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.
