Can I buy gems with silver in guild wars 2?
Yes. See the second top-most tab in the Black Lion Trading Company browser.

Yes. And gold too, since 100 silver = 1 gold. Just open up your Trading Post and look for the Currency Exchange tab.

you’ll need to have gold not silver, it’s not going to be that cheap.
Actually right now 9 silver buys 3 gems (The price changes all the time.). So you can buy gems with silver.
