Bridal jewelry which is inexpensive can be good to medium quality, and if it's cheap sterling silver jewelry or gold jewelry with semi precious stones or titanium bands or cubic zirconia imitation gemstones, it is likely to be good value.
The main reason to choose cheap bridal jewelry is that many people feel it is better to have something spectacular and dazzling for one day then something minuscule that costs a fortune. This may well be truest when it comes to the bridal accessories and bridesmaid sets that can cost a fortune and is a needless expense.
A beautiful pair of chandelier cubic zirconia earrings (or teardrop earrings) for the bride can be as little as $20 or$ 30 for the most delicate and sparkling pair set into a high quality costume jewelry setting, perhaps silver or other metal. They will not fall apart quickly, although eventually they will lose their shine. But for one day or two days or a special occasion they are more than adequate.
Also many hair salons that specialize in bridal makeup and hairdos will often offer a selection of hair ornaments and bridal accessories that will work well with your personal look. Since your stylists will know what makeup you will use, what dress design you have chosen and will have spent hours discussing your bridal needs and trying styles and listening to your dreams, they will be in a great position to recommend some cheap jewelry options and often have a selection of such unique and cheap bridal jewelry options right there in the salon or have catalogs for online jewelry distributors that they recommend.
Cheap jewelry online is often a way to save money but may also be a great time saver because shopping for jewelry in a shop makes you feel pressured and the last thing you need is to choose a set of bridal accessories or cheap jewels for your wedding because a salesperson was pushy. Online you can shop comfortably at your pace and without any sales stress. The prices are often lower due to the absence of overhead to maintain a fancy bridal shop, and these savings are reflected in the prices you pay.
