This beautiful unique tree of life pendant is 30mm in diameter, just big enough for people to take notice. I used a bold color changing yellow material to really show off the tree of life in your pendant. It is paired with an 18'inch bright yellow cord necklace bring this little piece wearable art all together. Simple enough to wear with your everyday clothing yet still unique enough to stand out.
