Crystal Effect Insulated Mug

The appeal here is the surface. Each mug is finished to look like a cut mineral, with an uneven, faceted texture and colour that shifts depending on how the light hits it. No two read exactly alike, which is what stops a set of them looking mass produced on a shelf.

Underneath the finish it is a practical everyday mug. The double wall keeps a coffee hot longer than a plain ceramic one and keeps the outside cool enough to hold without a handle wrap. It goes in the microwave and the dishwasher, so it can be a daily mug rather than something that lives at the back of a cupboard being admired. It holds a standard mug's worth of coffee or tea, and the tapered base sits comfortably in most cup holders, so it travels easily between car, desk and kitchen.

Seven finishes, and they are different enough to be worth choosing between. Agate and amethyst are the softest, rose quartz the warmest, obsidian the most graphic, and volcano red the one that stands out on a desk. Blue ore and green ore have the strongest mineral veining. A single mug works as a gift on its own; a mixed set of four makes more sense for a household where everyone wants their own.
