Rare Collector Orchids good as Gold

According to detectives it was a professional job and the thieves, who left no trace, knew exactly what they were after. Bearing all the hallmarks of an audacious art gallery heist this was the scene at Kew Gardens in 2014 where a rare African water lily was snatched. It is now thought to have been sold to an unscrupulous private collector on the growing black market for stolen plants.

The legal plant trade amounts to £9 billion a year worldwide. Dr Richard Thomas says: “There is a kudos in owning anything rare. Although it’s impossible to give precise figures for plants there is a limited but thriving black market involving fanatical but unscrupulous private collectors. If someone wants a species badly enough they will pay vast amounts of money.”

Rare and new discoveries of wild plants are most prized sending collectors into a frenzy and it’s feared that some species are being driven to the brink of extinction by over-harvesting. One of the world’s rarest orchids was re-discovered in 2014 by British botanists on a volcanic island in the Atlantic. There were only 250 plants of the unique species on the island of Sao Jorge in the Portuguese Azores, making it the rarest in Europe.

Lady's Slipper orchids

The albino form of the Vanda sanderiana or the Waling-waling is a rare and prized plant for orchid collectors and breeders.

Bulbophyllum kubahense

Phragmipedium kovachii was first found in 2001 and is referred to as one of the most important natural history discoveries of the last decade.

Cypripedium calceolus. It receives round-the-clock police surveillance where it grows on a Lancashire golf course.

Paphiopedilum rothschildianum, an orchid that is on top of the endangered species list.

The contemporary orchid-breeding business in Taiwan and its main rival, the Netherlands, centers on the Phalaenopsis, or the moth orchid. In Victorian Europe, orchid hunters, hired by wealthy collectors, sometimes killed each other in pursuit of new breeds.

Bornean slipper orchid

Shenzhen Nongke orchid was developed in the lab by agricultural research corporation Shenzhen Nongke Group. The orchid took eight years to develop and in 2005, it was sold for about $ 200,000.

Nanodiamonds

Nanodiamonds are tiny crystals only a few nanometers in size. While they possess the crystalline structure of diamonds, their properties diverge considerably from those of their big brothers because their surfaces play a dominant role in comparison to their extremely small volumes. Suspended in aqueous solutions, they could function as taxis for active substances in biomedical applications, or be used as catalysts for splitting water.

Researchers have, for the first time, levitated individual nanodiamonds in vacuum. Nanodiamonds trapped at atmospheric pressure are continuously agitated by collisions with the air molecules around them. Trapping the diamonds in vacuum removes the effect of all these air molecules. "This allows us to exert mechanical control over them," said Levi Neukirch, lead author of the paper.

"They turn into little harmonic oscillators."

One of the most promising ways to capture, generate and manipulate photons is with nanodiamonds. The secret is to create nanodiamonds with a defect in their structure where a nitrogen atom has taken the place of a carbon. Quantum physicists are interested in these so-called nitrogen vacancies because they can capture, store and emit the quantum information that photons carry. What’s more, they do all this at room temperature. It is even possible to manipulate this information using magnetic and electric fields.

According to a study featured in Nature Nanotechnology, the possible uses of nanodiamonds are endless. Nanodiamonds have excellent mechanical and optical properties, high surface areas and tunable surface structures. They are also non-toxic, which makes them well suited to biomedical applications. “These little gems have a wide range of potential applications in tribology, drug delivery, bioimaging and tissue engineering, and also as protein mimics and a filler material for nanocomposites”. Nanodiamonds have been used as catalysts in scientific experiments, seeding material for cultivating diamond films, additives for automobile oils, galvanic coatings and polishing compounds.

Nanodiamonds have made the most headlines for their potential use in fighting cancer.

Nanodiamonds could be the solution for dealing with chemoresistant cancer stem cells, according to a study published in ACS Nano. A team of researchers has repurposed existing chemotherapy drugs into effective agents against chemoresistant cancer stem cells with nanotechnology.

Sediments found beneath the floor of Lake Cuitzeo in central Mexico support theories of a major cosmic impact event 12,900 years ago. A 13,000-year-old layer of sediment contains materials associated with impact events, such as soot, impact spherules and nanodiamonds. The nanodiamonds found at Lake Cuitzeo are of a variety known as lonsdaleite, even harder than “regular” diamond and only found naturally as the result of impact events.

It’s thought that a large asteroid or comet entered Earth’s atmosphere at a shallow angle 12,900 years ago, melting rocks and causing widespread destruction. This event would have occurred just before a period of unusually cold climate known as the Younger Dryas. The only other widespread sedimentary layer ever found to contain such an abundance of nanodiamonds is found at the K-T boundary, 65 million years ago. This corresponds to the impact event that led to the extinction of the dinosaurs.

Crater of Diamonds State Park "Esperanza Diamond"

Mike Botha, a master diamond cutter with Embee Diamonds, is headed to Little Rock, Arkansas to work with the Esperanza diamond. The Esperanza is an 8.52 carat diamond that was found in the Crater of Diamonds State Park in Arkansas.

He got a chance to peer into the heart of the uncut diamond last week, using special equipment. He said it appears to be completely colourless. "This could be potentially, a flawless diamond." It is icicle-shaped, so he had to come up with a unique design to maximize the beauty of this particular diamond. He said the baseline value for the Esperanza is $200,000, but it could go much higher.

The Crater of Diamonds is a 911 acre state park in Murfreesboro, Arkansas that contains a 37.5 acre plowed field in which visitors can literally dig for diamonds. It's the world's only diamond-bearing site that's accessible to the public.

The largest diamond ever discovered in the US, the 40.23-carat Uncle Sam, was found there in 1924. It was cut twice, resulting in a final 12.42-carat (2.484 g) M-color, VVS1 clarity emerald-cut diamond. In 1971, the Uncle Sam was sold for $150,000.
