Spring 2007 colors are same as the fall 2006 colors, lightened a few tones. Gray will be the new neutral, but will be softened and toned to easily pair with the mid-tones of green, blue, gold, and strawberry.

Fashion jewelry looks will nicely complement feminine attires. Black will carry over from the holiday season, but will be joined with white in the form of pearls, quartz, white agate, white ceramic, and white enamels. Pearls in multi strands or long ropes, fancy colors, or exaggerated sizes will all be prevalent for spring.
Gemstones, especially sapphire, aquamarine, and tanzanite will be dominant in jewelry for spring. Specially if paired with pave diamonds or crystal in large cocktail rings, the look will definitely be very spring.
Big, bold, and long will be the three most important style trends for spring jewelry. Chains will consist of open links, uniquely shaped links, or hammered links; sometimes paired with beads.
Bracelets will be bigger and thicker.
Keeping all these trends in mind you can already go out shopping for the next season.
