About this 3.51ct natural oval diamond

This 3.51ct natural oval sits in the three to five carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1519597589. Listed at 5 retailers as of November 2, 2026, with prices from $81,132 to $102,234, a $21,103 spread on the same certified stone. 77 Diamonds lists it at $102,234. 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.
