Occasionally one might come across an unusual colored perfume bottle. One might be inclined to think that this might have been a special limited edition or even perhaps a prototype. More than likely, the bottles have been artificially induced via radiation (sometimes done with the aid of a microwave or industrial good sterilizer). This would cause some glass to be a deep shade of purple or amber. from what I have read online, this appears to devalue a bottle, but some people collect these flacons for their aesthetic beauty rather than their investment value.
In the case of these Guerlain flacons, they have been intentionally artificially induced to an amber shade and older bottles are also artificially altered into the purple shade.
Please do not purchase these bottles in the hopes that it is "rare" or a "limited edition".
Ebay seller (clancy_kid) is irradiating old bottles hoping to get higher prices for these very common bottles.
