There are many reasons to choose estate jewelry versus new pieces.
Jewelry depreciates much like new vehicles; meaning the moment you leave a store, your jewelry is worth less.
This equates to more for your money, meaning better and larger stones.
You'll find unique pieces as opposed to the mass produced generic designs that litter big box stores.
Often the craftsmanship is better. Unfortunately the adage that "they don't make things the way they used to" stands true for jewelry.
It's also environmentally friendly. No new mining is involved in estate jewelry pieces. They are carefully inspected and repaired or restored where necessary. There are exquisite diamonds and precious stones available without the need for more mining.
