This is a lovely gold plated lotus pendant. The chain is 16" long and removable.
In Buddhist symbolism the lotus is symbolic of purity of the body, speech, and mind as while rooted in the mud, its flowers blossom on long stalks as if floating above the muddy waters of attachment and desire. It is also symbolic of detachment as drops of water easily slide off its petals.
As something that is associated with rebirth, it is no surprise that the lotus flower is also associated with death, and the famous Egyptian book of the dead is known to include spells that are able to transform a person into a lotus, thus allowing for resurrection.
