Good Emerald Method For Levels Near 45?

What's the best way to grind emeralds out for my level (46)?

 

At that level you shouldn't need too many emeralds, but seeing as you can buy a Breathing Helmet II, I might suggest diving in the Seavale Reef next to Selchar.

You dive for various valuable items like sunken gold, pearls, and jewels, and sell them to a Treasure Merchant back in Selchar to make emeralds. There's no danger involved(except drowning, but that's why you have the breathing helmet).

 

Thanks for the help!

 

I forgot to mention. You can see what items sell for what price at the merchant, and in the reef there are a few caves with loot chests in them as well. If you don't feel like making the swim, spend a few emeralds and bring a teleport scroll or boat so you can make a quicker return. If you see a diamond or some strange black and yellow object, grab them. They're the most valuable.

 

OR you can farm the wolf den in nesaak as the wolves and wendigos there have a high spawnrate.

There is also a Tier 3 chest there sometimes
