Lightwood Engagement Ring

The Lightwood Engagement Ring is a Lightwood family heirloom. It is a vintage, 18-karat gold, Burmese ruby and diamond 3-stone ring, charmed to pulse and glow in the presence of demons.

History
The ruby, shaped into an oval surrounded by two smaller diamonds and attached to an 18-karat gold band was crafted by a female warlock in the early 19th century in London, England. A spell cast on the jewel enchanted it into reacting to, and alerting the wearer of, the presence of demons.

Sometime during the 1800s, the ring ended up in the possession of Benedict Lightwood, after having inappropriate relations with the warlock who crafted it. He ended up gifting it to his wife, Barbara Lightwood, who passed it down to their son, Gideon Lightwood. Since then, the ring has been given to the eldest child of every generation when they choose to marry.

In You're My Forever, Maryse gives the ring to Alec, who gifts it to Emilia for their 1 year anniversary to symbolize their promise to one another of "always and forever" and "someday". Emilia proceeds to wear it on a necklace, until Alec officially proposes to her in Someday Is Today.
