About this 0.51ct natural heart diamond

This 0.51ct natural heart sits in the half to three-quarter carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1545903800. Listed at 3 retailers as of November 6, 2026, with prices from $1,021 to $1,264, a $243 spread on the same certified stone. 77 Diamonds lists it at $1,264. 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.
