Possessions that you would consider "prized" belong not in a box in the garage or on a dusty shelf, but on display so everyone can enjoy them. Though some larger items might need to be mounted on their own (that Picasso that's been hiding in the attic might require an entire room to itself), a well-placed curio cabinet is just the ticket for smaller treasures, especially for those that are a part of a set.
Traditional Curio Cabinets
A traditional curio is generally made of hardwood and glass. They come in many forms, from tall to short, cylindrical to rectangular, but all are meant to display and accent whatever you decide to put into them. Though it is quite easy to find traditional looking curio cabinets that are brand new, it is often worth the effort to shop around online and in secondhand stores. You may be able to find one that not only suits your purposes, but has a bit of history to it, as well.
Contemporary Curio Cabinets
If your home décor is a bit more on the modern side, you might do well to opt for a curio cabinet that is more contemporary. Though they can still be made of wood, many of these curios are fashioned of metal and mirrors to truly accentuate the pieces they hold. The mirrors are generally positioned in such a way as to offer a good view of the objects in the cabinet from multiple vantage points. They are also quite helpful for viewing the side of the object that is not facing outward, without the need of actually taking the object out of the cabinet. Unlike a traditional model, a contemporary curio cabinet will most likely need to be purchased new.
Installing a Curio Cabinet
No matter what style cabinet you purchase, it is important to make sure that it is fixed solidly in place. Since they are most often used to hold things of value, curios need to be extra stable. You don't want your valuables falling down if the cabinet gets bumped into (not to mention the fragility of all the mirrors and glass).
Curio cabinets with flat backs can usually be anchored to a stud in a wall pretty easily, and often come with hardware designed just for that purpose. Round curio cabinets might be a bit more tricky, but with a little imagination, they can usually be fixed to a stud using just a few nails or screws, and a little bit of wire.
Placing your Cabinet
Where you put the cabinet in your home definitely boils down to personal preference. If you have a lot of space, you might consider putting the curio in a room that needs a touch of flavor. Those with limited space could easily make use of a curio cabinet that hangs on a wall or a model that is designed to fit into a corner.
Wherever you put it, try to optimize how your prized possessions look with the appropriate lighting. Many contemporary curios come complete with all the lighting you'll need, but if you are going for the traditional look, you may have to come up with your own lighting scheme.
