Blue diamonds may be blue because of where they are formed

Blue Diamonds are the world’s most expensive diamonds,  some stones worth tens of millions.

Why they are blue has long been know, But until now nobody has known how rare blue diamonds are made or where they come from.

Now scientists have discovered that they are formed 400 miles below the surface of the Earth, around four times the depth of cape series or white diamonds.

This is where the element boron can combine with carbon in such extreme pressure and heat that it crystallizes into the world’s most precious stone.

And because boron is mostly found on the Earth’s surface, scientists believe that it must have traveled down into the mantle when tectonic plates slipped beneath each other.

 Eventually volcanic action brought the diamonds up closer to the surface.

Blue Diamond is categorized as type IIb crystal and due to their extreme valuable, it is very rare to find one for scientific research purposes. An rare to find one that contains inclusions.

Jewelry Buyers Still Desire In-Store Experience

Consumers still prefer speaking with jewelers before making a purchase, despite the recent rise in online purchases, a survey has found.
Some 64% of people who bought jewelry visited a store to consult with an expert while deciding what to buy, according to a study released last week by Jewelers of America (JA). That’s 26% more than for other luxury items, the trade body’s online survey of 2,019 consumers showed.
Consumers who talk to a jeweler during the research process are also more likely to buy from a local store rather than online, the organization added.
“For consumers, seeing is believing, and they still rely on the expertise and knowledge of their jeweler,” said David Bonaparte, CEO of JA. “The jewelry shopping experience is different from other luxury purchases, and even in the rise of e-commerce, customers increasingly prioritize the in-store shopping experience.”
Even so, the brick-and-mortar trade is fearful of the impact of online sellers. In a separate JA survey of 257 of its members, spanning retailers and suppliers, 39% of jewelry retailers considered e-commerce to be their biggest competition.
However, only 34% of retailers surveyed actually have an online sales platform. At the same time, jewelers are working on improving their in-store experience by ensuring they have well-trained sales staff and high-quality customer service, the trade association added.
Jewelry self-purchasing is more popular for precious-metal products, JA found, with 56% of consumers considering gold jewelry to be a good choice as something to buy for oneself. Some 40% put sterling-silver jewelry in this category, while pieces containing diamonds and gemstones were more likely to be a candidate for gifting. Overall, 50% of consumers thought fine jewelry had sentimental value and helped to mark special occasions, JA said.

Debmarine Splashes $142M on Diamond Ship

De Beers is planning to add the world’s largest custom built diamond mining vessel to its fleet at a cost of $142 million.
The ship will be the sixth belonging to Debmarine Namibia, a 50/50 joint venture between the miner and the Republic of Namibia, De Beers said Tuesday. Expected to begin operations in 2021, it will enhance the company’s ability to recover diamonds off the southern African country’s Atlantic coast, the rough producer added.
“There is a great amount of potential in Namibia’s marine diamond deposits, and this new vessel will support our strategy to continue to grow our offshore operations,” said De Beers CEO Bruce Cleaver.
Earlier this year, De Beers launched the MV SS Nujoma, the world’s largest diamond sampling and exploration vessel. Acquiring the new ship will help the company capitalize on that vessel’s work, and support the long-term future of Namibia’s diamond sector, Cleaver added.
Kleven Verft, a Norwegian ship-building company that constructed the Nujoma, will also build the new vessel, and has signed a memorandum of understanding with De Beers.
