  • The Golden Ratio necklace will arrive in a pretty bag ready to be given as the perfect gift for Mathematician, Architect, Teacher, math lover or anyone else who needs a bit of geometric perfection in their life!
  • The Golden Ratio spiral pendant combines four Fibonacci triangles to form a swirl of aesthetic perfection! Cooler yet, the side of the pendant is etched with the Fibonacci Sequence.
  • A line segment is divided into two segments, and the ratio of one part to the whole is equal to the ratio of the other part to the part. This is the golden ratio. Represented in nature, mathematics, architecture, art, and even faces, the golden ration is now represented in this beautiful necklace.

The necklace looks like it is pictured, but it is lightweight and feels like it isn’t metal, even though it is. I think, wearing it, the necklace will get moved all over the place as it doesn’t have the weight to keep it sitting nicely in one spot. The chain is not very nice looking and detracts from the pendant. I will be getting rid of the chain and will hang it on a nicer one. So for me, disappointing over all. But if you like lightweight necklaces and don’t mind the chain, then it could be worth it for you.

SIZE OF PENDANT: About 1-1/2” diameterQUALITY : Nice and very light weightCHAIN QUALITY: Very nice, NOT “buy by the spool” cheap chain. This is pretty and shinyCHAIN IS SHORT: almost 19” + extension 2”- BUT extension chain is “NOT USEABLE”—- missing the “end jump ring.”- the end of regular chain - not extension - they made with the smallest size jump ring I could buy on Amazon.The lobster claw clasp is fine, but thicker. It DOES NOT FIT the size of jump ring…. Without many efforts to try to get it to “hook” on the “tongue” of the “lobster claw”… the part that moves.REQUIRES REPAIR BY YOU OR A JEWELER.I would recommend —-1. Add larger jump rings so that when you or someone else wants to put the necklace on, you “don’t need a magnifying glass to see the jump ring!”2. Add probably another 4-6” extension so you have more options on how to wear this.NOTE:Since the end jump ring is missing, this pendant easily slides off chain. You could buy a choker metal ring and put this pendant on that, for a different look.Then the chain, once you add correct size jump rings, you could turn this into a double bracelet easily.SEE PHOTO - you can see how tiny the jump ring is that comes on this.( I make jewelry, so I am just redoing mine. These Fibonacci discs are hard to find in this style.From other sellers they sometimes get rose gold and gold.)
