Amber can be white, yellow and orange to reddish brown. Transparent amber is more valuable than cloudy material. However, interesting plant or animal inclusions add to the value of any amber specimen.

What to look for
Colour is an important quality factor for amber
Amber comes in more colours than just yellow and golden. It might also be white, yellow and orange to reddish brown. Connoisseurs value reddish amber more than golden amber. Rare pieces can even be blue or green. Pieces which show an attractive bluish or greenish fluorescence can be highly valuable.
Although transparent amber is more valuable than cloudy material, an interesting plant or animal inclusion adds to the value of an amber specimen. Treatment can clarify cloudy amber somewhat. The resulting amber sometimes exhibits crack-like circular marks called sun spangles.
Carat weight allows for precise measurements
Amber is surprisingly light: in fact, it will float in a saturated salt solution—but not in ordinary seawater. This makes it suitable for large beads or pendants that are still comfortable to wear despite their size.

Tips & Advice
1. Be bold with amber.
Amber’s light weight makes it the perfect choice for large earrings and chunky bead necklaces - even dramatically scaled designs are still comfortable to wear.
2. Keep amber away from heat.
Amber can melt or burn in high temperatures. Don’t store amber on top of electronics or in strong light. It’s normal for amber to darken over time, and heat and light can accelerate the process.
3. Be wary of perfect-looking insect inclusions.
The insects in amber are millions of years old and generally aren’t perfect. Amber imitations with modern insects or other types of small animals inside are very common.
4. When in doubt, get a lab report.
For a significant purchase an independent laboratory report can confirm that the amber you are buying is natural and that an inclusion has not been added later.
5. Amber that’s a bright green is a treated material.
The bright yellow green colour of “green amber” is a result of heat and pressure treatment. The final product is valued accordingly.
6. Ambroid, pressed amber, consolidated amber or reconstructed amber is a composite.
When small pieces of amber are pressed and bonded together under heat and pressure to make larger pieces, the result is marketed as pressed or reconstructed amber, which sells for less than non-consolidated pieces.
