Kate Middleton’s Engagement Ring was Princess Diana’s

The engagement of Prince William with Kate Middleton has everyone talking. Prince William gave his soon to be wife his mothers wedding ring. This is the only way of making sure that my mother didn’t miss out on today” said William as he and his fiancé post for a picture in St. James’ Palace.

So if any of you guys are wondering what the ring look like here is a short description: it’s a dazzling oval, 18- carat blue sapphire and white diamond ring.

Prince William waited and proposed the right way. He asked her father for Kate hand first before proposing to her. He then popped the question and asked her. However he was very nervous when he did, he said “I was not sure she would say yes. How could I be?”

Pope Paul VI's jewelry for sale in eBay auction



An opulent jeweled cross and ring once owned by Pope Paul VI sits in a North Carolina jewelry store awaiting the winning bidder for an eBay auction.

As odd as it may sound, it is true; the Wilmington store owner is a Southern Baptist with a flair for self-promotion - allowing him to meet with figures such as UN Secretary General U Thant and Evel Knievel. This interesting journey began with Paul VI's decision to have some of his jewelry to be sold to raise money for charity.

One of the jewelry pieces is a pectoral cross, given to clergy who achieve a rank as bishop or higher. The eBay post advertises that the ring is a 12.75-carat diamond solitaire cut encircled with smaller diamonds. The cross holds 12 main diamonds over 60 carats in total diamond weight, and is coated in smaller diamonds and emeralds.

Paul VI donated the ring and cross to the UN during a 1965 visit, requesting that they be auction and the proceeds to be used to charity. Chicago jeweler Harry Levinson purchased the set in 1967 for $64,000, and the money was divided among 4 UN agencies. Over the years, the jewels changed hands several times, and was even owned at one point by Evel Knievel.

Presently the owner of jewelry store, Perry's Emporium, has ownership of the papal jewelry.

"This is new for me," said owner Alan Perry, who estimates that the items may fetch somewehere between $800,000 and $900,000 at auction. "That's why we're going to put it up on eBay. It's only worth what someone's willing to pay for it, and eBay might be a good measure to see if people are interested."

Perry plans to put the jewelry set on public display starting April 14 through Holy Week, with armed security watching closely.

Natural Sapphire Company Produces A Royal Blue Sapphire Ring

The Natural Sapphire Company has created a ring styled after the royal ring that Prince William gave to his Fiancée, the same ring that once belonged to his mother, Princess Diana.

This royal blue sapphire ring is 69.35 carats, with very, very slight inclusions (VVS2). At the center of the ring sits a brilliant blue sapphire stone surrounded by 16 round diamonds equaling to a total of 8 carats, with all of the stones intricately set on a platinum band.

The price of the ring comes to a total of $1.5 million but there are smaller versions of the ring being offered from between $1,000 to $100,000.

Flawed Diamonds perfect for Quantum Memory

Scientists have found a way for diamond crystals to store quantum information.

Atoms are manipulated inside the diamonds so that they hold information long enough for quantum memory, encoding information in states that are both 0 and 1 at the same time, not the strings of 0s and 1s calculated by conventional computers.

The perfect diamonds for these are not from Harry Winston, Tiffany & Co., or the type to sell to buyers like World Jeweler. Flawed diamonds work best.

David Awschalom of University of California, Santa Barbara reports, “Oddly enough, perfection may not be the way to go. We want to build in defects.”

Nitrogen stands as one of the most common defects in diamonds, turning the stone yellow. When a nitrogen atom is next to an empty spot in the carbon crystal, the atom gives off an extra electron that moves into that spot. Several  years ago, scientists have learned that using microwave energy can change the spin of those extra electrons, and have put them to work as quantum bits, or qubits.

Awschalom discovered how to connect the electron spin to the spin of the nearest nitrogen’s nucleus, providing a more stable way to store information. Triggered by magnetic fields, this transfer happens very fast at about 100 nanoseconds.

Diamond memory works at room temperature. The electron spins within the diamond can be manipulated and measured by shining a laser light into the diamond. This could provide high potential for scientists to use diamonds for developing nanophotonic systems to move and store information in packets of light.

Quantum memory isn’t forever, but it does last for quite some time by quantum standards. The nuclear spin stays coherent, or stable, for a little more than a millisecond, with potential to last up to seconds.”

Sebastian Loth, physicist at IBM’s Almaden Research Center in San Jose, California, clarifies, “You can only do your quantum magic as long as you have coherence. If you have a lifetime of milliseconds, that lets you do millions of operations.”

A Hollywood Icon and her Diamonds

Widely known for her Hollywood legacy and her love affairs, Elizabeth Taylor admits that her greatest love affair was with her jewelry.

“You can’t cry on a diamond’s shoulder, and diamonds won’t keep you warm at night, but they sure are fun when the sun shines,” Taylor once said about her collection.

Some key statement pieces of her diamond and jewelry collection include the Krupp diamond, the 69-carat Taylor-Burton diamond, La Peregrina Pearl, and the Taj Mahal Diamond.

She even marketed her love of jewelry into a brand, imbued notably in her classic “White Diamonds” fragrance, whose ad campaigns often had her draped in gems and diamonds.

In 2002, the actressed published “My Love Affair with Jewelry,” an oversized volume chronicling her prolific jewelry collection.

Additionally, some of her most regarded jewelry pieces come from her tumultuous marriages to Richard Burton, with whom she met on the set of “Cleopatra.”

The Taylor-Burton Diamond

They acquired the Krupp diamond, the Grand Duchess Vladimir Suite, the La Preregrina Pearl, and the massive Taylor-Butron Diamond, a 69-carat pear-shaped diamond. For Taylor’s 40^th birthday, Burton gifted her with the heart-shaped Taj Mahal diamond.

Some of her most treasured pieces were gifts from her ex-husband Mike Todd, who would lavish her with jewelry “just because.” Showman Mike Todd gave her a suite of Cartier diamonds and rubies just for swimming laps in a pool.

Taylor would deliberately wear her jewels uniquely. During the time she worked with hairstylist Alexandre de Paris, he would find ways of adorning jewelry into her hair, such as fastening a broach or weaving a string of pearls into an updo.

Later in her years, Taylor would often lend her jewelry to museums for exhibitions. “I am only their guardians.  Just like a painting, you can’t own jewelry,” she said.

 Dame Elizabeth Taylor passed away March 23, 2011, at the age of 79.

Tiny Diamonds could be a new weapon against Cancer

US researchers have reported that they can fight late-stage breast and liver cancer tumors by using tiny carbon particles known as nanodiamonds. These nanodiamonds work with potent chemotherapy drugs to shrink normally chemo-resistant tumors.

This is not the type of diamond adorned on jewelry and accessories. Without the nanodiamonds, the drug would be ineffective on the tumor or even be rejected by the body; or higher doses of it would be too powerful for the patient to survive.

"This is the first work to demonstrate the significance and translational potential of nanodiamonds in the treatment of chemotherapy-resistant cancers," explained the results of the study, published in the journal Science Translational Medicine.

Chemotherapy drug resistance results in treatment to fail in 90% of cancers that have spread inside the body, or metastatic cancer. The new research development shows promise to be used by humans in the future.

The lead author Dean Ho of Northwestern University reports that "What is most interesting from this study is when we took an even higher dose of the drug, the dose was so toxic that the animals all died. They didn't even last long enough to finish the study."

"But when we took the same higher dose and bound it to the nanodiamond, not only did all the animals survive the study, the tumor sizes were the smallest we saw in the study."

Nanodiamonds are usually formed in explosions, such as in coal mining or oil refinery operations, and may also have formed from meteorite landings.

"What is neat about it is it is almost like a waste material, it is going to be produced anyway," said Ho.

"So instead of throwing it out, taking this by product and simply processing it with things like acid washing, milling, sonification, it can yield very uniform particles of between two and eight nanometers in diameter."

Ho estimated that it would likely be a few more years before the therapy would go on the market; researchers would first have to look at how the technique works in larger animals before human clinical trials can start.
