Lab-Grown Diamonds are about to get Even Cheaper

Lab-Grown Diamonds are about to get Even Cheaper

Ever since laboratories managed to grow gem-quality specimens consistently and at scale, "synthetic" diamonds have steadily gained popularity with today's jewelry buyers. In addition to being conflict-free and eco-friendly, the main advantage synthetic diamonds have over natural ones is cost. Now, a manufacturing company called Plasmability has patented a new production methodology that may drive down the price of synthetic diamonds even further.

Ordinarily, diamonds are grown using chemical vapor deposition (CVD). As part of the process, a tiny fragment of carbon is placed into a pressurized chamber filled with a carbon-heavy gas (usually argon, methane, hydrogen, or a mixture of the three). The gas mixture is heated to very high temperatures with microwave to produce a plasma. In its plasma state, the gas breaks down and its carbon atoms accumulate and crystallize onto the fragment of solid carbon, causing it to grow. Since the layers of diamond only form at a rate of <60 microns per hour, the process can take up to 10 weeks and requires lots of electricity.

Instead of microwave technology, Plasmability’s method uses an inductively powered toroidal radio frequency generator to heat the gas and create plasma. As a result, the conversion of electrical energy into heat energy improves in efficiency by about 35%. As a bonus, the toroidal radio wave technology is smaller and requires less maintenance compared with microwave generators. If laboratories invest in this technology, we could see further decreases in diamond prices within the next few years.

Types of Bullion and Their Uses

May 22, 2019 07:00

Purchasing bullion is a great way to diversify a hard-asset portfolio. Of course, the amounts and types of precious metals you buy are important factors in investment diversification – but what about the types (i.e. form factors) of bullion?

One of the common questions first-time investors ask when they see all of the ingots, bars, coins, grains, rounds, and other types of bullion available is “what’s the difference?” Since the inherent value is the same, there is no strategic advantage to owning, say, coins instead of bars. But, there are some reasons why investors may prefer one form factor over others.

For example, bullion coins’ smaller sizes and difficult-to-counterfeit designs give them better liquidity compared to ingots, bars, or rounds. However, seigniorage fees typically push the cost of bullion coins over the spot price for their metal content. So if you can afford to purchase more metal at once, and you have a secure space to store that amount, you’d save some money upfront by purchasing bars instead of coins.

In the infographic below, we’ve outlined the key differentiators for the most popular bullion products: bars, coins, and fractional.

Humanium - A New Alloy for a Good Cause

Humanium - A New Alloy for a Good Cause

Peace does not come through prayer, we human beings must create peace. Also, power of truth is more powerful and enduring than the power of gun. Therefore, the Humanium Metal by IM Initiative is a laudable effort at making this world more peaceful through concrete human action.” -Dalai Lama

Does that make Humanium the antithesis of prayer? Not exactly, but it does make it a commendable follow-up. So what exactly is Humanium metal?

Humanium is a metal that's made from melted-down guns. More specifically, it is recycled metal from illegal firearms obtained from gun destruction programs.

The Story behind Humanium

The brainchildren behind Humanium are two Swedish creative agencies, Great Works and Akestam Holst. Their pro bono campaign, Humanium Metal by IM, garnered attention when it won the Grand Prix for innovation at the 2017 Cannes Lions International Festival of Creativity.

The campaign also drew the interest of IM Swedish Development Partner, which has a long history of working in countries where gun violence is hindering development.

They coordinated their efforts and in 2016, launched the first weapons destruction program dedicated to Humanium Metal by IM in El Salvador. The program generated three tons of Humanium from nearly 5,000 weapons. The initiative has since expanded to Guatemala, with Honduras and Columbia expected to follow.

How Humanium Is Used

Humanium can be recycled into all sorts of things, including buildings components, machinery, utensils, tools, bicycles and jewelry. In fact, Sweden’s Arild Links currently sells a charm bracelet made from Humanium. And last year, watchmaker TRIWA began using Humanium to create custom watches.

And there’s more to come. Through future brand collaborations, Humanium Metal by IM hopes to explore the production of even more Humanium-based products.

Is Humanium Certified?

Since Humanium is made from seized firearms in full cooperation with local governments, each batch comes with documentation provided by their respective melting plants, along with technical specifications. The process is also monitored by the non-profit association, Swedish Fundraising Control.

Consumerism with a Cause

Humanium might be the perfect metal for socially conscious consumers who prefer to buy from brands with pro-social messages and ethical business standards. Humanium Metal by IM uses proceeds from its sales to fund nonviolence initiatives in the areas it sources from. By purchasing Humanium products, consumers can, in turn, help the world become a better, more peaceful place.
