Moonstone guide

Among the Gemstones of Ancient Isle, Moonstone is the white one: a pearlescent stone usually linked to magic. It is listed with a weight range of 0.5 kg to 2.8 kg and no bait, weather or time conditions, so what you have to go on is its value and weight.

The average value is C$850, 341st of the 742 documented fish by average value. The maximum weight ranks 582nd of 663 fish with a documented maximum, so it is a light item. It is a modest return, but it does not depend on the weather.

Other gemstones documented on Ancient Isle are Opal and Ruby, so the isle gives you a small set of stones to collect. The rods sold in the zone are Krampus's Rod, Phoenix Rod and Stone Rod, which means you can gear up there and go looking for all three stones in one session.

The advice is practical: treat Moonstone as an easy addition to a gem run, not as a target on its own. It will not change your income, but it also asks for nothing special. If you are already fishing Ancient Isle for the Mosasaurus or the Meg parts, anything it adds is a bonus. If you are looking to improve your earnings, it does not pay enough to be the reason you go.
