About this 1.85ct natural heart diamond

This 1.85ct natural heart sits in the one-and-a-half to two 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 1166332816. Listed at 14 retailers as of October 29, 2026, with prices from $17,329 to $29,325, a $11,996 spread on the same certified stone. MOH London lists it at $29,325. 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.
