Vintage Moser pair of fit-together alexandrite perfume or cologne bottles. I had to spin them, but I know at least one side fits together.....and I know these are early....at least c1950s. That is when I have seen these Moser pieces that "fit together" per se. They are cut and beveled so nicely. Would be fun to display one with one with "white" light, and the other in "regular/sun" light then pull them out and it would be magic for some. Excellent condition with one bottle slightly different.....slightly smaller but both are about 7 1/8" tall assembled. Last photos shows color change.
