Kat Florence Announces Rare Collection of Neon Titanium Tourmaline from Botswana

With an extraordinary luminous glow, Tourmalines from around the world are widely considered to be one of the most beautiful colored gemstones. Jeweler Kat Florence knows about the magical attraction of Tourmalines. Recognized as one of the most famous designers for Paraiba Tourmalines she has made a name for herself among collectors.

Currently the jeweler holds the world record for the largest gem quality Neon Paraiba ever sold at auction in 2016, a Top Blue 91.43 carat flawless gem. Now Kat Florence makes collectors hearts beat faster again with a collection of exclusive Titanium Neon Tourmalines from Botswana.

When Gem Hunter Don Kogen showed up at the Kat Florence studio in 2018 with his latest discovery, the jeweler was amazed at the quality of the Tourmalines: “Even in their uncut form the stones sparkled and glowed. I have never seen anything like it. The uncut stones were so completely different from what I have experienced with Tourmalines in the past”.

Don Kogen explains that Paraiba Tourmalines have always been renowned for their fine neon colors. It is the trace element Copper that makes Paraiba sparkle like no other Tourmaline and what actually makes metallic bearing Tourmalines so special. When Don Kogen discovered a small pocket of Titanium bearing Tourmaline in Botswana he immediately realized that he was looking at a very rare phenomenon that has never been unearthed before.

Kat Florence says demand for fine grade color gemstones are on the rise, with new records being broken regularly. The most recent auction record set at Christie’s for Tourmaline was in May 2018 for a 14.27 carat matching pair of Neon Paraiba Tourmaline earrings selling at $2,778,000 ($194,000 per carat). With less than 200 of these rare Neon Titanium Tourmalines ever discovered, it will be interesting to see what price the rare Tourmalines will fetch at auction. Kat Florence explains: “A selection of my Neon Tourmaline pieces have been on display in museums throughout Europe, Asia and the US since 2019”.

October Birthstones: Tourmaline and Opal

October is another month with two birthstone choices, Tourmaline and Opal

Tourmaline

Tourmaline has become a favorite gemstone among jewelry designer, and gem collectors the world over. Since it is available in a wide variety of colors, it is ideally suited to almost anyone’s taste. Tourmaline also is known for displaying several colors in the same gemstone.  These bi-color or tri-color gems are formed in many combinations; gemstones with clear color distinctions are highly prized.

Tourmaline is found in many localities including Brazil, Afghanistan, East Africa, and the USA.

Opal

The name opal derives from the Greek Opallos, meaning ‘to see a change (of color)’.  Opals range in color from milky white to black with flashes of yellow, orange, green, red, and blue. An opal’s beauty is the product of contrast between its color play and its background.

Opal is a formation of non-crystalline silica gel that seeped into crevices in the sedimentary strata. Through time and nature’s heating and molding processes, the gel hardened into the form of opals.

Of all the precious gemstones, opal is perhaps the most alluring.  A unique mixture of silica and varying amounts of water, opal’s brilliant play of color is the result of tiny silicon spheres measuring several hundred nanometers in diameter, the same width as the wavelength of visible light. What makes an opal precious and another nonprecious is how those spheres are organized:

The opal is composed of particles closely packed in spherical arrangements. When packed together in a regular pattern, a three-dimensional array of spaces are created that give opal its radiance.

Once considered the most prized precious stones by European royals, opals were traditionally given as favors in the 1800s.  Even Napoleon adored the stone, giving his wife, Josephine, a vivid red opal weighing roughly 140 grams.  The first opal to be named, ‘The Burning of Troy’ was aptly labeled since Napoleon had said that he gave her this stone because she was his Helen.  In spite of such royal favor, the opal is the only one thought to bring bad luck. This notion swept the opinions of nineteenth-century Europe after the great success of the ghost novel ‘Anne of Geierstein’ by Sir Walter Scott, in which a drop of holy water turns a supernatural opal talisman into a common pebble and soon after which the heroine dies.  So convinced of this superstition was Princess Alexandra, wife of King Edward VII, that when Queen Victoria died, the new queen removed the ‘unlucky opals’ from the diamond and opal tiara her mother-in-law had commissioned and replaced them with rubies from Ceylon, which remain there today.

Quite possibly the most famous opal in history was owned by a Roman senator named Nonius in 35 BC. Originating from the mines of Czernowitza, the only source for opals at the time, the fabled stone was only the size of a hazelnut yet was valued at two million sesterces, or enough to buy a villa in a nice part of Rome. So obsessed with the stone was Mark Antony that the amount of pressure he applied to Nonius, who had no intentions to part with the stone, to sell it to him caused Nonius to self-imposed exile, leaving behind all his property and taking only his precious opal. Even Pliny, the famous Roman author, called opal a gemstone which combines the best possible characteristics of the most beautiful of gemstones: the fine sparkle of Almandine, the shining purple of Amethyst, the golden yellow of Topaz, and the deep blue of Sapphire, so that all colours shine and sparkle together in a beautiful combination.

Today, roughly 97% of opals come from Australia, and of all the opal produced in the world 60% is white opal, 30% is crystal opal, 8% black opal and 2% boulder opal. The town of Coober Pedy, which means ‘white man in a hole’ in Aborigine, produces a major amount of opal, however, the mines in Mintabie and Lightning Ridge produce the rarer, more valuable black opal. The ‘white’ or ‘black’ of an opal refers to the stone’s body color on which the ‘flashes of light and color’ play, with the black offering the most brilliant play of color. Much detail has gone into valuing black opals, even so far as differentiating the seemingly endless types of patterns. The more vivacious and bright the play of color, the more valuable the opal.

In honor of October’s birthstone, I have put together some of the most beautiful opals ever seen and the most famous ones ever recorded.  Consider this my birthday gift to all those born in the month of October.
