I'm serious.
I was completely appalled! And offended because I love vintage - clothes, shoes, furniture, books and, especially, jewelry. I've collected vintage jewelry since high school and found some amazing pieces. But if I ever needed an argument just take a look at these amazing vintage pieces:
This necklace is made of vintage broaches strung on a crystal necklace. So gorgeous.
The following two brooches I found on eBay. They are very Art Nouveau and are amazingly detailed


This is the back of the second brooch. Look at the workmanship.

Vintage is a great way to get a unique look and great quality, often at an affordable price. Plus, sifting through eBay or going to antique shows is fun and a great way to hone your eye and find what the market is charging. Plus you can see what is hot or getting popular.
Branch out with your choices. I think it's better to have something unique than some generic piece that anyone could buy off of QVC or in the mall.
