If you have school-aged children, back to school is a mixed time for the whole family. You kids may face the beginning of another year with excitement, trepidation, or a bit of both. Depending on whether you are in the position to stay home with them, you might miss them, or be relieved to have time to get stuff done. Or both. And we all can remember the uncertainty of a new year, perhaps a new school, as we smell that first tinge of autumn in the air.   Perhaps this is the year to make a small jewelry purchase part of back-to-school shopping. Wearing a bracelet or earrings you chose can remind your son or daughter of your love, values and protection when faced with changes and challenges.   Amidon has a variety of pieces appropriate for that first piece of “grown-up” jewelry. For less than $100, you can buy your middle school or high school daughter something she can treasure for years, but which still looks suitable for a teen.       Want your daughter to always remember the love of two parents? Buy her this ring which features two silver hearts joined with a small diamond accent.             This heart-shaped pendant features a blue diamond. She’ll wear this close to her own heart.
