An adjective for expressing beads freed from a beaded necklace

Start from the vision of a suddenly broken beaded necklace, from which all beads seem to escape, falling down to the ground and bouncing away. My English is imperfect, yet a sentence I can think of would be:

The *** beads broke away from the neck of their elegant hostess.

I thought about unleashed, unchained, freed, released, yet I cannot catch this positive (like a child joy) feeling.

Is there and what is an adjective to describe how this inanimate object (bead) seems animated by free will (and freedom)?

unstrung - You even get some alliteration. ;-) (You also get a double meaning, which might or might not be appropriate in context.)

Adjective: unstrung ,ún'strúng

Emotionally upset

"the incident left him unstrung and incapable of rational effort"

Verb: unstring (unstrung) ,ún'string

Remove the strings from

"unstring my guitar"

"Liberated" or "Suddenly Liberated" might work...

The suddenly liberated beads broke away from the neck of their elegant hostess.

Liberated has the connotation of freedom, release from bondage or captivity, and although it works well in the sentence above, is commonly applied to people or animals - so you also get the shading of life-like behaviour.

From Dictionary.com:

Liberate verb (used with object), liberated, liberating. 1. to set free, as from imprisonment or bondage. 2. to free (a nation or area) from control by a foreign or oppressive government. 3. to free (a group or individual) from social or economic constraints or discrimination, especially arising from traditional role expectations or bias. 4. to disengage; set free from combination, as a gas. 5. Slang. to steal or take over illegally: The soldiers liberated a consignment of cigarettes.

Emancipated!

Emancipate: To free from bondage, oppression, or restraint; liberate.

American Heritage® Dictionary, 5th Ed.

Thus, emancipated means freed from bondage; liberated.

You might consider untethered.

to free from or as if from a tether

Merriam-Webster

Like a horse that's been untethered from a post, the beads have become loose and free to scatter and roam.

tethered adj. fastened with a tether; limited, confined, ‘tied’.

Also, on the topic of figurative language related to releasing animals, you could consider a figurative analogy related to release doves.

A release dove is a breed of rock dove (domestic pigeon) used for ceremonial release. Release doves are often used to commemorate important milestones of life and offerings of hope at weddings and birthdays and as representing the soul's final journey at funerals. They are also released at grand openings, sporting events, and many outdoor gatherings.
