have the distinctive "Diamond-O-I" marking just under the "7".
(Note: The "I" can appear as a dot in the middle of this mark like with this bottle, though on most it is a more or less distinctive "I".)Reading down through the narrative in Question #11, we find out that the number just to the right of the Diamond-O-I mark is the last two digits of the year the bottle was manufactured, which on this bottle is a "46".
Ob für Weihnachten, Muttertag, Ostern, Valentinstag oder einfach so; bei uns finden Sie immer das passende Geschenk für einen lieben Menschen.
Wie wäre es mit einem personalisierten Schmuckstück?
If one looks closely at the thick glass in the base of the bottle, one can see that the glass is not quite perfectly colorless, but instead has a slight "straw" or washed out amber tint to the glass (picture of base below).
