Featured Sterling mantra symbols bracelet

As near as I can tell, this is a Buddhist mantra bracelet. The 6 symbols in a circle on the clasp, repeat on each link. Is the center symbol a tughra? What is the meaning of the symbols? Origin?

 

.... So, AI says the mantra is for compassion, Om Mani Padme Hum. The cross symbol on the clasp is a Vajra or Dorje which is a Buddhist symbol representing spiritual strength, protection, and indestructibility.

 

Very cool-is this some type of a Buddhist 'rosary', or perhaps something worn by pilgrims ?
Guesstimate on age ?

 

Think pretty new, though bought on the secondary market. Saw some brand new ones being offered. Sellers are not good in their descriptions. Hence the questions.

 

In the 70s I knew people in New York, many connected or hoping to be connected with theater, who had a butsudan on their wall & chanted this mantra in the hope their lives would come together. It was the age of the Hare Krishnas, est, Dianetics & I don't know what all.

 

It is a Vishvavajra, with four ends. A Vajra has two ends.

This is an explanation a certain someone wrote elsewhere on the forum:

"The Vishvavajra is one of the most powerful symbols in Vajrayana Buddhism, it stands for the four winds and the powers that created the physical unverse. It also ensures harmony between all sides and between the worldly and the spiritual.
On the base of a statue it serves to ground a heavenly being and connect its essence with sentient beings."

In the link are also photos of my Vishvavajra and one of my Vajras, for comparison.

 

Thanks! I knew not to totally trust AI, but it was the best information I found.
