How to Identify Markings on the Bottom of Crystal Antiques

Collecting antiques can be a fulfilling hobby, providing great investment potential as well as possible financial rewards, if you ever decide to sell your collection. Crystal antiques come in every possible shape and size you can imagine -- from animal figurines to ashtrays, chandeliers, vases, bowls and dishes. Identifying the markings on crystal is relatively easy, if you know how to go about it.

Things You'll Need

Jeweler̵7;s loupe or magnifying glass
Digital camera (optional)
Antique collector̵7;s value and identification guides

Instructions

- 1
  Turn over your crystal antique so you can view the bottom. Make sure you have plenty of light.

  Look for the mark, and make sure you can see it clearly. Check with a jeweler̵7;s loupe or magnifying glass, to enlarge the mark. If you still can't make it out, take a photo with a digital camera. Load the photo onto your computer, where it will be enlarged so you can see the mark more easily.
