About this 0.45ct natural heart diamond

This 0.45ct natural heart sits in the sub-half-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 6565252053. Listed at 2 retailers as of November 1, 2026, with prices from €457 to €530, a €73 spread on the same certified stone. 77 Diamonds lists it at €530. 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.
