This the Tree of Life pendant stands 3cm from the bottom of Malkuth to the top of the pendant bail. The bail has a 2.7mm diameter hole and should be used with a 2mm chain.
The design is based off Robert Wang's diagrams created from descriptions by the Golden Dawn of the qabalistic tree of life. The small versions were created for casting in precious and semi-precious metals.
