About this 1.23ct natural heart diamond

This 1.23ct natural heart sits in the classic one-carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2537627410. Listed at 4 retailers as of November 4, 2026, with prices from $5,876 to $10,085, a $4,209 spread on the same certified stone. MOH London lists it at $10,085. 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.
