Wow! Thanks so much @TheRoyalWatcher! The Schaumburg-Lippe Tiara is indeed spectacular and a sight to behold! Reminds one of the tiara that belonged to the Dukes of Devonshire.
I’m kinda excited about you sharing this news because I’d found the other day this beautiful picture of Princess Marie Anne of Saxe-Altenburg, Princess Consort of Schaumburg-Lippe wearing some diamond ornaments as brooches that awfully resemble the elements that form the tiara.
What do you think? Could they be a match??
