You have found the woman (or man) of your dreams and are ready for the next step. You even know exactly what the engagement ring will look like. The problem is, you can't find exactly what you have in mind. It may be time to design your own engagement ring. Designing a custom ring is not as difficult as you may think. Start by picturing the two parts of an engagement ring -- the stones and setting -- and begin sketching or writing down specifics. Decide the materials you want in your ring and you are well on your way to the ring you envisioned. The Stones A first step is deciding what types of stones will be in the ring, how many there will be, and their relative sizes. Diamonds are most common, but your engagement ring can have other gemstones as well. Rubies, pearls, emeralds, and sapphires can all add special meaning. Some questions to consider when choosing stones: Do you want a large, single solitaire or a center stone surrounded by smaller stones? If cost is an issue, which matters more: how large the stones are or their quality? Do you want diamonds only, a combination of diamonds and other gems, or no diamonds at all? How will they be arranged? Plan the appearance by sketching how the stones will be configured and labeling them by type. The Setting You can choose from several types of metal and quality. Each has unique features and appearance. White or yellow gold (14 or 18 carat) are common choices, as is platinum. Titanium is also a viable choice. If you are not already familiar with the differences in appearance and quality, take a trip to the mall or nearest jewelry store. Notice the finish of each and how it catches the light. Other features to consider are the size and shape of the setting. It should reflect the bride's personal style. Also consider hand size and balance. A large ring can overwhelm a small hand. Conversely, a large hand may diminish a small ring. Assuring Quality It pays to know something about quality before ordering a custom ring (or any piece of fine jewelry, for that matter). Become familiar with the 4 C's of diamond quality: carat, color, clarity, and cut. Price should depend on the quality of each attribute. Unless you know the jeweler, do not take his word on these. Independent laboratories, such as the Gemological Institute of America (GIA, gia.edu), grade individual diamonds. Yours should be certified in writing and come with a certificate detailing it's unique features and quality ratings. Most online retailers that provide custom service list diamond inventory online along with scanned copies of the certificates, so you know exactly what you will be getting. Where to Shop Now that you know exactly what you want, where do you shop? Chances are a local jeweler can make the custom ring. But, local is not your only choice. Several online jewelry stores offer custom rings and ship them worldwide. Some simply assemble and ship the ring from a variety of inventoried settings and stones. Others take a more personalized approach by making a sketch or mold based on pictures or a detailed description of what you have in mind. They then create the ring based on the approved design. Search "custom engagement rings" or "design your own engagement ring" to find online vendors. There you have it. How to design the engagement ring of your dreams!
