About this 3ct natural heart diamond

This 3ct natural heart sits in the three to five carat band, graded D 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 1559832241. Listed at 8 retailers as of November 4, 2026, with prices from £22,572 to £34,669, a £12,097 spread on the same certified stone. Diamonds Direct lists it at £34,669. 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.
