Sir, your jewel Hath suffered under praise

Timon
Sir, your jewel
Hath suffered under praise.
Jeweler
What, my lord? Dispraise?

Things of like value, differing in the owners,
Are prizèd by their masters. Believe ’t, dear lord,
You mend the jewel by the wearing it

Timon
A mere satiety of commendations.
If I should pay you for ’t as ’tis extolled,
It would unclew me quite.
Jeweler
My lord, ’tis rated
As those which sell would give. But you well know
Things of like value, differing in the owners,
Are prizèd by their masters. Believe ’t, dear lord,
You mend the jewel by the wearing it.
Timon
Well mocked.
Merchant
No, my good lord. He speaks the common tongue,
Which all men speak with him.
