Travel / My first journey to Poland, travel questions. [10]

Hello Everybody

This week I will be making my first journey to Poland.

I will need to get a taxi from Warsaw Airport to the South East area - towards Chelm. Can anybody advise please how much that will cost? And how long it will take in time?

And can I ask for a translation please of the below;

Złoty pierścionek z tanzanitem (1,35 ct),
6 brylantów (ca 0,28 ct),
wzór: 826 B DI
cena: 4.390 zł

Any help and I would be extremely grateful.
Many thanks
Paul
