Vintage Bohemian style bracelet featuring semi precious stones

This is a bohemian-style bracelet featuring multiple semi-precious stones in oxidized or antiqued silver-tone metal settings. The bracelet includes:
• 5 oval cabochon stones in earth tones: amber/cognac, green (possibly aventurine or prehnite), smoky quartz or labradorite, another smoky/grey stone, and yellow/citrine
• Each stone is set in an ornate bezel with decorative beaded/granulated detailing around the edges
• Oxidized or blackened silver-tone metal finish gives it a vintage appearance
• Chain link extension for adjustability
• Hook clasp closure
• Measures approximately 15-17cm based on the ruler shown
• Bohemian/southwestern jewelry style
The stones appear to be natural semi-precious varieties, though without testing it’s difficult to confirm exact types.
