There's all kinds of great jewelry to be had for under $25. I love this rosewood bracelet ($20) from the Curiosity Shoppe. Made out of a single piece of thin rosewood veneer. Great for the earthy nature-lover on your list.
Or, for a little glitz theseBlu Bijoux star and moon rings ($26) with enamel and crystal look way more expensive than they are. Available from Max & Chloe. I can't decide which color I like best.
Make a wish! These Brazilian good luck bracelets ($5) will make your wish come true when they wear and fall off. They come from the mystical city of Bahia, Brazil and have been known to grant wishes for the past 200 years. They come in a several different colors all with a qoute in Portuguese that reads "In remembrance of our patron saint of good luck in life." Buy 5 in all different colors!
These wool reindeer socks ($19) are festive and warm for the holidays. Knit in a wool, cashmere, angora blend, they are available in three colors from Sundance.
Plaid is so trendy right now. Keep warm and on trend with this soft acrylic scarf ($28) from Shopintuition.com.
