The best crystal comb will be appropriately styled for the occasion, fit into your overall aesthetic, and be priced within your budget. There are many types and styles of crystal combs which range from faux crystal to fine jewels. They are available at brick and mortar stores, online retailers, and through catalogs. Crystal combs are often found in wedding boutiques since they are popular accessories for brides.
Even before you start shopping, determine your budget. A crystal comb can be very expensive or relatively cheap, depending on the brand and quality of stones. Unless you have an unlimited budget, there's no real reason to purchase an expensive crystal comb. There are many faux crystal combs which just as beautiful as the authentic versions.
You should also consider when and where you plan to wear the comb. A crystal comb is naturally sparkly and eye catching, so it is more like a piece of jewelry than a hair clip. Keep in mind that the larger the comb the more formal the statement. Typically, crystal combs are worn on very formal occasions, like weddings. The exception is a small, relatively plain comb which can add elegance instead of extravagance to a hairstyle.
Once you have decided on your budget and style needs, you're ready to start shopping. It's easier to pick the best crystal comb in person. You can try it on, inspect its quality, and see how it looks with other accessories. If you must shop online or through catalogs, check the company's return policy before buying. Make sure that you allow enough time to try the accessory and ship it back if necessary.
When you're looking at crystal combs, consider the overall appearance first. Remember what role you want the accessory to play. If it's a statement piece, it should be big and bold while an accent comb should be smaller and more subdued. Be sure to look in a three way mirror so that you can judge how the piece looks in relationship to your head and hairstyle. If it looks off balance, keep shopping.
Consider the embellishments of the comb. It should coordinate with your other accessories and your style. Many combs are traditionally designed with pearls and mother of pearl inlay, but if this doesn't match your aesthetic, look for different decorative elements.
Don't be overcome with the beauty of any one crystal comb. For instance, a Victorian era antique can look gorgeous in its own right. The problem, however, is that it will look odd if your outfit is a bohemian style dress and flip flops.
When you find a comb that suits your taste and your budget, check it carefully for damage or signs of poor quality. The crystal should be firmly wired or mounted to the comb with no loose stones or beads. There should also be no sign of discoloration, even if it is made from imitation crystals and plated metals.
