          Absolutely gorgeous! Came a bit tangled but I was able to get it out. I got it as a gift and it's amazing!

          I really like the pendant portion of the Fibonacci necklace, I'm not in love with the gold chain, I just don't like the look and style of it all that much. I'll probably change it to a silk cord. However, I'm really pleased with my purchase and will certainly buy more items from Boutique Academia.

          I love the Fibonacci necklace which I ordered in the gold finish. It is sturdy, yet delicate and very different. I plan to order it in the silver finish, too, so I can wear it with different color clothing.

          My wife had selected two necklaces from the Boutique Academia catalog for her wishlist. She then received two of one of them. Boutique Academia exchanged the extra for the one she didn't receive and shipped it at no charge to us. Oh, and my wife loves the two necklaces!

          I purchased the silver fibonacci pendant and necklace from your company and gave it to my girlfriend for Christmas. It's delicate and very feminine on her neck, where originally I was afraid it would be too large. She's barely taken it off since and it shows no corrosion. The chain and pendant itself are very fragile, so take caution.

          This necklace is beautiful and high quality! I love that the design is elegant and also subtly nerdy. I got compliments right away from the first time I wore it!

          The formula works, people started to comment, first it was 1, then 2, 3, 5, 8, 13, 22 and it just kept on growing. A beautiful pendant and crafted very well indeed. So much better than the cheaper variety. I love wearing it.

          Finding jewelry for my wife is tough. She likes putting meaning into the things she wears. This company was a god-send for me this Christmas, and she absolutely loves the necklace I got her. Thank you Boutique Academia!

          Great piece. I was looking for years for a pendant that I would enjoy wearing every day. I wanted something that was beautiful to look at, yet had meaning for me. This piece, mixing art and science, is perfect. The only issue I had was with the chain as it was a bit too short, but I switched it out for an easy fix.

          This was a gift for my daughter when she won a writing contest at her university. The title of the short story included the word Fibonacci, so this was an ideal present. She loves it! The necklace is dainty and delicate without being flimsy. A lovely piece of jewelry. She is already getting compliments, and it makes for a great conversation piece.

          I got the necklace because of my love for math, and now its part of my everyday outfit. It goes with everything i wear, whether its formal or casual, and it allows me to show my love for math without saying anything. I completely recommend this necklace to anyone.

          This is a great website with unique and wonderful gifts for that special person in your life who loves and appreciates math and science. The gifts they have cannot be found anywhere else with such great prices and quality. I bought a silver Fibonacci necklace as a gift for my math loving Ph.D daughter and she loved it. She wanted to know where I found such a great gift.

          As the review title says, this necklace wasn't for me. Instead, it was a gift for a friend who had just gotten confirmation on a math and physics teaching post. I still haven't seen her since the necklace arrived but when it did I immediately received a message and saw a post on Facebook from her; she absolutely loved it. I don't doubt that it'll be seeing plenty of use in the future.
