I couldn't decide if this 1940s Retro Modern rose-gold-washed sterling silver brooch with large faceted sapphire glass stones and diamanté accents by Reinad should be worn horizontally or vertically until I saw Anne Baxter wearing a set like this in the 1946 movie Angel on my Shoulder. Her brooch was perfectly placed in the vertical position on her dress at the base of its V-neckline. She even wore the matching earrings. The brooch has a roll-over safety clasp, and the earrings are screw-backs.  I've included a photo of the brooch in the horizontal position, so you can decide if you prefer it that way. You can see a similar piece that was shown in the 1945 catalog of Bennett Brothers (a jewelry wholesaler). The page was entitled "New Pink Gold Finish on Sterling Silver — Styled by Master Craftsmen" (who were not named). The brooch shown in the last photo was $28.50 retail, and the earrings were $13.50, or $42.00 for the set. (While I don't have income statistics for the mid-1940s, to put these prices in perspective, the U.S. government reported that by 1950, the average American household's weekly income was about $81.)
