Gift for a friend

Purchased the extender with a Blue Ring Glass necklace as a gift for a friend. The extender made the necklace the perfect length, and therefore an ideal gift.

Nonstop compliments!

I love my new Smart Glass necklace! It’s both beautiful and comfortable to wear. Each day that I have worn it, complete strangers have stopped me to say they love it and ask where I got it! I love that it looks as great with business attire as it does with my weekend ripped-up boyfriend jeans ;-) It also makes me feel really good to support creative small businesses who use up-cycled materials. Win, win, win!!! ❤️

It's a bit large but will certainly work

Gin Love

I purchased this beautiful necklace for a friend who loves Bombay Sapphire gin! It was a birthday present and she was thrilled! She couldn’t believe it was made from a gin bottle. Thanks so much for the beautiful jewelry ❤️
