Where to get Jewel Coral in Lost Ark

Finally, new adventurers entering Prideholme are guided to the town’s luxury goods merchant in a whirlwind of store tutorials and new character introductions. Its marketplace, while rather limited, offers three types of mountable turtles, each of which seems to cost a strange new currency – Jewel Coral.
While players will continue to encounter these luxury goods merchants in all major cities during their early travels through Arkesia, it seems they will never get their hands on any of the jewel corals these merchants are after. It wasn’t until much later in the Lost Ark story and progression system that these players would be given the opportunity to obtain one – and only one – of this super rare coral.
Unlock Jewel Coral: Turtles Ahoy

Towards the end of her first journey in Luterra, Prince Thirain will offer the player a ship to travel the world in search of the seven arks. While this instruction is the driving force behind the MMO’s main questline, players can also sail in any direction the wind takes them, including to the myriad islands that dot the seas.
Turtle Island, located equidistant between the continents of Anikka and Pleccia, becomes available to the player once their character reaches level 50. On it, adventurers can find a boy named Flynn who, after being raised by a bunch of turtles from birth, begins to think he is one.
Flynn, along with his primary turtle handler, Baham, will task the player with a series of quests designed to help him better establish his turtle side, complete with snorkels, flippers, and a shell of his own. This questline takes players to Anikka, Arthetine, and Vern, which requires the player to progress by acquiring the first few Arks.
Upon completing the final quest in the series, To the Sea, the player will be rewarded with a Jewel Coral.

Purpose of Jewel Coral: Uniquely one-sided

Despite its uniqueness and inherently once per character, the Jewel Coral obtained from Flynn can only be exchanged for Turtle mounts. These turtles, which vary in color from green, yellow, and azure, each cost a Jewel Coral, meaning each character that completes Flynn’s questline has only one chance to earn their favored reptile palette.
The bulky shells don’t slow these mounts down one bit, as all three turtles are equally equipped to keep up with the back half of Lost Ark’s mounts. Traveling at 420 units per second, the Turtles can tether most of the provisional mounts players likely found early on in their Luterra journey.
