Prime Number Steel Rope Necklace. Is leather cord not your thing? How about stainless steel rope chain instead, with the same pendant containing the first 739 prime numbers in an area of less than 1/2 of an inch.
The primes are masterfully printed at .9 point. That's 9/10 of a point in size. Super tiny. Super crisp.
The Prime Numbers Steel Rope Necklace is a unique and fun math jewelry experience. It's sure to be a conversation piece.
