Baguette Tennis Necklace Brilliant, but not too blingy. Most tennis necklaces don't come with an extender chain. Ours does, so you can easily mix it into your necklace stack and wear it high or low. Our simulated diamonds bring the striking look tennis necklaces are known for. Dress it down with a white tee, or pull out all the stops for your next glitzy night out.
