About this 0.54ct natural heart diamond

This 0.54ct natural heart sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6562234542. Listed at 2 retailers as of November 6, 2026, with prices from £494 to £575, a £82 spread on the same certified stone. 77 Diamonds lists it at £575. 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.
