'I am a brain, Watson. The rest of me is a mere appendix.' A perfectly Holmesian declaration — razor-sharp, a little imperious, and utterly brilliant. This keyring is for the deep thinkers, the puzzle solvers, and everyone who has ever felt that their mind is their greatest asset.

The main quote pendant comes with a scarf charm as well as your choice of initial and birthstone crystal. The stainless steel keyrings are a standard split ring style and measure approximately 1.2 inches / 30mm.

The birthstone crystal is a genuine Preciosa. Preciosa crystals are made in Europe.

The quote is sealed beneath a glass dome and set in a silver plated backing to give a luxury finish.

Handmade by Bookmark & Co in our UK studios.
