George Frederick Kunz,
Rings for the finger
(1917)
“ While the natal gem in a simple but effective setting is the most appropriate ring for a girl or boy, a small seal ring for the boy, when he is about 12 years old is not unfitting, the seal being so well-executed that it may serve him when he has reached manhood. For very young children, no stone can be given the preference over the turquoise, which in its delicacy and beauty of color cannot [160] be excelled. ”
