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 3565240050. Listed at 3 retailers as of October 31, 2026, with prices from £284 to £353, a £69 spread on the same certified stone. 77 Diamonds lists it at £353. 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.
