Speaking of jewelry, what are you familiar with? Diamonds, rubies, sapphires... Many people, hearing the name of tanzanite for the first time, can hardly remember it because of its cumbersome grammar. But what if I told you it had another, more familiar name, heart of the sea! Do you remember it at once?


In 1920, May persuaded famous silent film director George klein to shoot a full-length hope diamond mystery and played the main role himself. The screenwriter made up stories about discoverer tavinier being mauled to death by a dog (he died in Russia at the age of 84) and the failure of the malatans to survive in Britain.


McLean also adds characters to the story, including Catherine the second, the empress of Russia. These stories, as well as McLean's own subsequent misfortune, give the diamond a mysterious quality.


The "heart of the ocean" in the play is actually the name of the scriptwriter for the story; When filming Titanic, director James Cameron required every prop to be real, and diamond was no exception. Therefore, this dark blue tanzanite stone became the double of "hope" and became the real "heart of the sea" known to the public.


Tanzanite, also known as tetrahedrite. Early used as a decorative material, the blue and purple transparent crystal rose in the gemstone industry after its discovery in Tanzania in 1967. In honor of the new republic of Tanzania, it was named tanzanite stone, and it is also known abroad as danquan stone. This is one of the world's recognized emerging gems. The gem was first discovered in 1967 in the arusha region at the foot of the snowy mountains of the equator. In 1969, tiffany, a global luxury company, launched it into the international jewelry market.
