Amanda I, the precious

Amanda is a girl who has a very deep connection with her roots: her grandfather was a miner for precious stones and she loves the idea of polishing as a description to what she makes with her clients (she is an advertisement professional).
She has a necklace with the stone her grandad gave her, an unpolished stone with this metal little "cage".
And that was very clear to me: this should be the symbol of her brand.
