How can I tell the difference between a swarovski crystal and plastic?

Hey, I just bought a bracelet off ebay and it allegedly has a clear heart swarovski charm and another smaller red swarovski bead. However, I do not know how to make sure that they truly are swarovski crystal and not plastic. So, does anyone know any methods of checking it (without damaging the bracelet or seeking professional advice?)





Thanks |||I was told this as one way to check but I am not 100% sure how accurate it is - but having seen the method used - you will see a noticable difference.





Get a torch and shine it through the crystal - if it is true crystal you will get a crisp clear 'rainbow' effect of colours on a wall/ceiling. If it is plastic, the colours will be noticably less clear and will appear 'smudged'





Give it a go - if you have other crystal - try it on those first to get an impression of what it should look like.|||To be honest, I'd never actually buy anything branded Swarovski off of eBay just because of the sheer amount of fakes. The problem is mostly that even as soon as they put a tiny genuine Swarovski bead on something, people then try and pass the whole product off as Swarovski.





I've found a guide for you though so hope it might help a bit.|||take it for a valuation? it shouldnt cost that much or if you can do this with ur bracelet with a mirrow rub the peice across and if it makes a deep scratch its real if its plastic it will not mke a scratch|||I found a related article about on how you can determine the REAL and Fake Swarovski ....

|||On the point of the heart you should be able to make a small scratch on a piece of glass,plastic wont scratch glass





|||knock the crystals over the glass and you will tell by the noise, the plastic will give you hardly a noise
