I Liked The First Jurassic Park,

and out of interest often thought about buying a piece of amber, 

 with an insect inside it, or better still a lizard, but be warned, with a price tag of $10.45, if seems to good to be true then it is, a modern fake, if you look, the price starts for some of the same at $6.50 with free shipping! to be fair the advertisement does say, condition new, a brand-new, unused, unopened, undamaged item, but I wonder how many have bought a piece of fake amber with an insect inside it, but paid real amber prices, how do you tell the difference? Here goes,

You can easily rub amber with your hands or with a cloth to produce heat as well to see if it emits a tree resin smell. There will also be an oily residue that appears on your hands after several seconds of rubbing very fast.

Real amber also has an electrostatic charge, and when rubbed it will attract to things like your clothes, hair, or dust. 

In salt water, genuine amber will float while most fakes, which are denser in weight, will sink.

Authentic amber is fluorescent and shining UV light over it will glow pale

of course all of these are great if you are in a amber shop and have a glass of water to hand, but buying on the Internet? Buyer Beware! the above tips from Baltic Essentials.
