I came across a couple of interesting photos of Princess Astrid, Mrs. Ferner (of Norway) a while ago. I have never noticed that she has used chokers. But found some old pictures where it is clear that she has. The first picture shows her with a velvet choker and a large diamond brooch attached to it. Very interesting. I have not seen this piece of jewelry before. And can not identify the "brooch". The second one is very interesting too. That is Princess Astrid with a choker. It does not look like seed pearls, but of course, the quality of the photo is very bad, but it looks more "blingy" to me. Could it be one of the many diamond chokers of Queen Maud? A source told me that the chokers still exists, but due to fragileness and difficulty to wear them, they never do. In 2017, however, one of the Princess' daughter in laws (wife of Calle Ferner) wore a choker for the joint 80th celebrations of King Harald and Queen Sonja, it could also be an opportunity.
