Princess Irene of Greece and Denmark is one of my favorite royals. She’s such an enigmatic character, shrouded by a veil of mystery, always placed at the back following the order of precedence.
There’s not that much info about her jewels or what she inherited from her mother. All we know is that she most likely received the Pearl Necklace Tiara and Queen Sophie’s Diamond Circle Tiara.

In this picture the Princess is also wearing her loop diamond necklace that seems to have been made to match her diamond circle tiara.

In this other picture she is wearing a head band (made of diamonds maybe?) and a necklace never seen again.

In this picture she is seen wearing a pair of earrings that shares design with her mother’s ruby ear pendants that ended up with Queen Sofia. Princess Irene’s are set with what I believe are turquoises. She’s also seen wearing a seed pearl necklace with some other stones in it. On her right hand she’s wearing a four-row pearl bracelet and on her left hand she wears a bracelet that looks like the one from Queen Anne Marie’s Van Cleef and Arpels suite. (Thank u @royalwatcher I really liked your post on the suite

On this picture taken during a French State Visit to Greece made by President De Gaulle, Princess Irene is wearing her mother’s pearl/necklace tiara as well as a seed pearl necklace with a diamond clasp never seen again, perhaps it also became part of her inheritance.

I was also able to find this article of a Spanish magazine regarding an auction made by the Princess of her jewels, all of which seem to be of modern design (The proceedings of the sale were destined to charitable organizations)
The article is in Spanish, and the quality of the picture is really low, but I was able to translate some of the items descriptions.
The lot included:
*A bracelet of cultured pearls with a diamond and ruby clasp.
*A pair of brooches in the form of pineapples studded with brilliants and emeralds, designed by René Boivin.
*Also designed by Boivin, a set of brooch and earrings of turquoises, diamonds and gold in the form of flowers.
*A magnificent set of necklace, ring and brooch made of pearls and platinum.
*The most important item in the auction was a pair of earrings with rubies and diamonds that resembles strawberries.
*A ring of rubies with a big diamond of 10.5 carats in the center.
*An exquisite pair of earrings of diamonds and pearl pendants.

If anyone has been able to find pictures of the Princess in any other jewels that belonged to her mother or the ones described in the sale, pls post them! Thank you a have a lovely week!
