It is the most stunning of their alabaster colours and I think that's because it's made with gold ruby. It's truly beautiful.
As far as I remember CH said the alabaster range was produced from 1916.
And I recall the green was produced into the 1930s.
In CH British Glass CH says on page 108 that the pink
'is the firm's 'rose-du-barry' while the white was their 'eau-de-nil'' when referring to a pink alabaster lidded vase in the group.
However in the Crystal Years,
Williams-Thomas the pink is referred to as Rose (page 24).
And on the same page 24 Williams-Thomas says '
During the 1914 alabaster period, several colours - ....cinammon, rose ...- were all made.' indicating that it could have been produced from 1914.
My personal thoughts are that CH is probably right on the dating i.e. from 1916 but that the colour isn't their Rose-du-Barry as that seems to have been a shaded 'Burmese' type colour effect according to the Crystal Years book description of the colour.
Christine has given more detailed information on this pink colour already here in a previous thread:

Date wise - The Crystal Years page 26 has a badly written sentence that could indicate the pink alabaster was made up to 1938. On the other hand the sentence might indicate that only the jade green alabaster was made up to 1938. It's confusingly written.
