About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded E 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 5556481538. Listed at 10 retailers as of October 27, 2026, with prices from $7,012 to $12,792, a $5,780 spread on the same certified stone. Wholesale Diamonds Direct lists it at $12,792. 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.
