I'll give you a captain's guard here.

Bring all here at once.

We, you, and I, will seal it up, and I'll have old Ram Lal Singh secretly come here and value them.

He's the best judge of gems in India, and he was once an official in the Royal Treasure Chamber of the old King of Oude.

Less than fifty thousand pounds worth as a return would be a transparent humbug, and besides you can delay your signature for a day or so, till you and I, after listing the gems, see this old expert and have him examine them in our presence.
