Starlight Memories

Starlight Memories is an Armor shop in The Legend of Zelda: Breath of the Wild. It is a jewelry shop run by the Gerudo Cara and jeweler Isha in Gerudo Town. It sells jewelry that grants certain resistances based on the gems used to make them. These accessories are all considered head armor and consist of jewelry such as circlets and earrings.

Link can occasionally find the Hylian Vai, Jules standing outside of the shop. At first she is disappointed that the shop is closed. After the shop reopens she realizes she doesn't have the materials to have jewelry made and doesn't have enough Rupees to buy them outright, and concludes it is just not time for her to own one.

Side Quest
When Link first visits Gerudo Town, the shop has been closed due to Isha running out of the Flint she uses to craft the jewelry she sells. Talking to her leads to the Tools of the Trade Side-quest in which Link must bring Isha 10 pieces of flint. After bringing her the flint, Isha rewards Link with his choice of accessory made of either Ruby, Sapphire, or Topaz for free out of gratitude for help her. Completing this quest also results in Isha reopening her shop for business. Isha tells Link she will give him a special discount if he ever needs an accessory, though tells him not to tell her other customers.

Jewelry
After the side quest is completed, Link can purchase accessories here, though in addition to Rupees he is required to have a certain amount of gems (Amber, Diamond, Opal, Ruby, Sapphire, & Topaz) related to the item in question (such as 5 Topaz for Topaz Earrings for example).
