The bee bottles are available in white and gold bottles. The gold bottles are hand painted in gold and are significantly pricier. You can order whatever fragrance you like (EDC, EDT, EDP, Parfum) in 250, 500 or 1000ml. I've also heard that if you have an empty bee bottle, you can have it refurbished at the Champs Elysees store. A few Guerlain stores have bee bottles in stock (Harrods, and Harvey Nichols in Dubai can order it for you), but all Guerlain boutiques have them.
There are also a limited number of 1000ml white bee bottles for the Exclusive Guerlains (SDV, SlV, Vega, L'art, Les Parissience, etc...), and a handful of 500ml white bee bottles of Mon Preciuex Nectar (like the one in Mr. G's blog).
