About this 2.51ct natural oval diamond

This 2.51ct natural oval sits in the two to three carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1242101378. Listed at 12 retailers as of November 1, 2026, with prices from €19,363 to €31,206, a €11,843 spread on the same certified stone. Helzberg Diamonds lists it at €31,206. 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.
