World's Sapphire Diaries: From Most Expensive Necklace to the Vanished Tiara

Many of the famous sapphires in jewels usually worn at state banquets and grand ceremonies are often measured at up to 40 and some 60 carats, but I always wondered how large a sapphire can be to put it into a brooch or a tiara so it can still be wearable? How large can a sapphire become before it stops being a jewel and becomes a geological wonder? And why did one sapphire smaller than the giants still make history by selling for more than 17 million dollars in Geneva? This is where I made a research into some of the largest sapphires documented — gems so enormous that even a royal tiara could barely contain them.
So, in this video, you will have a journey through some of the most colossal sapphires and sapphires set into jewels which broke all records, yet with some disappeared after a long journey to New York.
