Until your bringing up a blue coral, I had never seen or heard of it before..  My first thought was it must be dye/stain..

But in fact there is a natural blue coral !

It is described as "not as stable" as other corals like apple or tiger type corals..  In fact for a lapidary, apparently great care is suggested while working it.

Here are a pair of small slabs intended for the making of knife scales. Also found some carved pendants that have the same appearance as your carved bottle.

Any coral intended to be carved from a lapidary perspective would have to be fossilized/agatized, and yes, yours does look fossilized/agatized
