About this 2.51ct natural round diamond

This 2.51ct natural round sits in the two to three carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 1559787256. Listed at 12 retailers as of October 30, 2026, with prices from $13,991 to $25,079, a $11,088 spread on the same certified stone. With Clarity lists it at $25,079. 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.
