Why wasn't the Heart of the Ocean necklace in Titanic real?
Inspired by the Heart of the Ocean, a 171 carat necklace with a real blue sapphire was crafted and ultimately sold for 1.4 million dollars


The Hope Diamond was not on the Titanic when it sank; it was owned by Washington socialite, Mrs Evelyn McLean, who didn’t even set sail on the infamous ship. When she died in 1947, it was sold to pay off her debts.

Frequently asked Questions
What is the royal history of diamonds?
In the 13th century, an act of Saint Louis (Louis IX of France, 1214-70) established a sumptuary law that reserved diamonds for the king based on their rarity and value that was conferred to them at that time. From that moment onwards, diamonds began appearing in royal jewelry for both men and women. From the 17th century, they were also seen with the greater European aristocracy and the wealthy merchant class.
The earliest diamond-cutting industry is believed to have been positioned in Venice (Italy) somewhere around the 1330’s. It is estimated that diamond cutting found its way to Paris and Bruges around late 14th century and later to Antwerp.
By 1499, the Portuguese navigator Vasco da Gama discovered the sea route to the Orient around the Cape of Good Hope, providing Europeans an end-run around the Arabic impediment to the trade of diamonds coming from India. Goa, on India's Malabar Coast, was set up as the Portuguese trading center, and a diamond route developed from Goa to Lisbon to Antwerp.
Are diamonds rare?
Diamonds are actually quite rare. Also it is true that the process of extracting diamond is quite laborious (mines move many tons of dirt per carat of diamond found) and that gem-quality diamonds are relatively few (only about 1 in 1 million diamonds are quality one carat stones, only 1 in 5 million are 2-carat; and 1 in 15 million are 3-carat).
The prices of diamonds increase along with the inflation rate. In some periods, the demand is higher than the supply whilst in other periods this is reversed. In the end, there is always a balance.
What colour is a sapphire?
The sapphire is instantly linked to an intense sky-blue colour. In this colour, the gemstone is also the most beautiful and most valuable. But not all sapphires are blue. They exist in different colours, including yellow, purple and orange. All sapphires were formed from crystals of the mineral corundum. The presence of certain metals in the corundum determine the final colour of the sapphire .
