Sapphire Bracelets

The Sapphire Bracelets are one of the four keys needed to open Reborn's core. It is called "the seal of love".
== In the game ==
The Sapphire key was originally in the possession of Solaris' family. One day, the keys are stolen by Radomus, who asks a friend to turn them into jewelery, but when working on the Sapphire key, it breaks into two, creating the Sapphire bracelets. As a travelling merchant, Radomus seeks out strong trainers that would protect the keys. Ultimately, he sells the Sapphire bracelets to Monty and Caroline Belrose, who choose them because it reminds them of Saphira's name. They later bequeath the Sapphire Bracelets to their second-oldest daughter, Laura. 
A few years later, Sirius sets fire to the Belrose Manse to get a hold of the Bracelets. However, Titania finds Tanzan Cove while hiking and picks them up from the house's ashes. She later gifts them to her best friend and love interest, Amaria, who values them deeply as a sign of Titania's apparent love for her.
When Amaria storms Blacksteam Factory with the player, the Bracelets attract Solaris' attention. After Amaria's suicide attempt at Celestinine Cascade, Team Meteor find her at the Water Treatment Centre and Taka has them treat her wounds; however, he also takes her Bracelets. Titania later confronts Taka, who gives them back without any resistance. Since he already informed Solaris about the Sapphire bracelets' whereabouts, Team Meteor soon storms Fiore Mansion to steal them. When they are beaten back, Sirius tries to burn down the house to make sure he gets the Bracelets at all costs, but TItania reacts by flooding the Gym and Team Meteor retreat. When Amaria reveals that she is amnesiac and does not remember Titania breaking up with her, Titania is unable to deal with the situation and runs off to her desert Gym. 
When the player finally reaches her Gym and is ambushed by Lin, Titania gives them the Sapphire Bracelets. Lin later insists that the player should hold onto the Sapphire Bracelets, which makes Titania wary of the player for a second. When the player seeks out Amaria for a Gym Battle, she reacts differently depening on the player's earlier choices: on the Zekrom path, she happily lets go of the Bracelets because what really matters to her is her relationship with Titania; but on the Reshiram path, she gets enraged that Titania gave the player her Bracelets and becomes resentful. On both paths, the player keeps the Sapphire Bracelets until reaching the Glass Workstation, where they are stolen by Bennett, who afterwards gives them to Laura, the original owner.
