Pliny gathered what was known and surmised about the stone in his time,
and recorded what to-day reads like a cluster of nonsense, though his
example is emulated by instructors in the press of the twentieth
century.
Probably
no one thing has attracted more indiscriminate writing than the
diamond. Since the qualities which make it precious became known,
writers have used it to " adorn a tale " almost as frequently as fair
dames use it to multiply their charms and oftentimes quite as

developed by cutting, when the natural octahedron, or stones with a

When, however, the brilliant possibilities of the diamond were developed, and it became the desire of kings
