Regal Strength with Grounded Energy
This plug features a powerful design where a finely detailed crown form rises around a smooth, polished Black Obsidian gemstone. Dark, luminous, and deeply grounding, this stone has been revered for centuries as a symbol of protection, strength, and energetic shielding, a talisman for those who move through the world with intention.
Black Obsidian is often associated with clearing negativity and strengthening boundaries, helping you stay rooted in your own power. Framed by the crown’s sculptural structure, the stone becomes the heart of the piece, a balance of raw presence and refined authority, control and flow.
Designed for those who wear jewellery with meaning, these plugs turn adornment into ritual. Worn solo, they make a bold statement of confidence; styled with other pieces, they anchor your ear curation with quiet dominance and undeniable edge.
More than an accessory, the Crownstone Plug in Black Obsidian is a reminder to stay grounded, protected, and unwavering in your strength.
