About this 0.37ct natural heart diamond

This 0.37ct natural heart sits in the sub-half-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2566320274. Listed at 3 retailers as of October 31, 2026, with prices from €323 to €435, a €111 spread on the same certified stone. 77 Diamonds lists it at €435. 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.
