I’m not crazy about jewellery, but I can certainly go with the following recommendations:
Listen, my son, to your father’s instruction and do not forsake your mother’s teaching. They are a garland to grace your head and a chain to adorn your neck.
Let love and faithfulness never leave you; bind them around your neck, write them on the tablet of your heart.
My son, do not let wisdom and understanding out of your sight, preserve sound judgment and discretion; they will be life for you, an ornament to grace your neck.
My son, keep your father’s command and do not forsake your mother’s teaching. Bind them always on your heart; fasten them around your neck.
