Sapphire Lantern

A sapphire lantern is a bullseye lantern that has a sapphire in place of its more usual glass lens. Making the lantern from scratch requires level 49 Smithing (frame) and 20 Crafting (to insert the cut sapphire).

Lamp oil needs to be added before the lantern can be lit if crafted with a Bullseye lantern (empty). This can be accomplished by either bringing swamp tar to the chemist in Rimmington, or using swamp tar on the Lamp Still at Miltog's market stall within Dorgesh-Kaan while the lantern is still in your inventory.

To make the sapphire lantern, the player must use a cut sapphire on a normal or unlensed bullseye lantern. If the lantern used had a lens, the player will receive a lens in their inventory. After the player is finished using the sapphire lantern, they may use a bullseye lantern lens to convert it back into a normal bullseye lantern and retrieve the sapphire.

The lantern is a light source and is used for attracting light creatures in the Chasm of Tears. Players need to use these creatures to traverse the cavern in the Tears of Guthix and While Guthix Sleeps quests.

When extinguished, the message You extinguish the lantern. is displayed.

The lantern can be made at any time, independent of quests and activities. The lantern is kept in the inventory on death.
