main view, black opal ring

Opal is the birthstone for October, but we think this gem should be celebrated year round! Opals are truly a wonder to behold. A hydrous variety of silicon dioxide, it’s composed of tiny silica spheres bonded together with silica and water. Known for their brilliant flashes of color, this optical phenomena is the result how the silica spheres are layered within the stone, scattering the light in different directions.

Opals come in a brilliant range of colors, including orange, yellow, red, green, blue, and purple. White opals are the most common. Found in Hungary, white opals feature flashes of color against a white, almost translucent, ground. Black opal, one of the more prized forms that is  mined in Australia, exhibits a play of color against a dark ground. Fire opal, so named for  its bright yellow, orange, or red background color, is primarily found in Mexico and Ethiopia.

Opals have been revered for centuries. Because the colors of other gems can be found in opals, the Romans considered opal to be the most precious and powerful of all gemstones. In the Middle Ages, opals were believed to bring good luck by embodying the virtues of all gemstones.

Although admired since ancient times, the reputation of this luminescent gem darkened in the nineteenth century. In this period, opal lost its luster thanks to the publication of Sir Walter Scott’s 1829 novel, Anne of Geierstein. In the novel, the character Lady Hermione wears an opal with supernatural powers that changes color according to her mood. After the opal is sprinkled with holy water, it loses its color, leaving her ill, and the following day, reduced to ashes. Scott’s decision to use the gemstone as a supernatural life source must have been inspired by the flashes of color seen on an opal when it’s exposed to light. Misunderstanding of this optical phenomenon, along with the stone’s delicate nature, inspired awe and superstition.

Unfortunately, Scott’s artistic license had consequences for the opal market, rendering this once lucky stone to be quite the opposite. In fact, within one year of its publication, sales of opals decreased by nearly 50% and remained low for the next twenty years. Superstition arose from a misunderstanding of opal’s delicate nature. They rank 5.5 to 6.5 out of 10 on Mohs scale of hardness, making opal more fragile than other stones. Because of their high water content, they’re particularly sensitive to sudden climate changes. While Sir Walter Scott exaggerated this sensitivity, it should be noted that the stone can crack under dry conditions, or rapid changes of temperature.

Like Sir Walter Scott, nineteenth-century American poet Hannah Flagg Gould was inspired by opal’s lifelike qualities. In her 1845 poem “The Opal,” she describes the stone as “the gem with the burning heart,” referring to the luminous spot that changes position in the light. Her interpretation is more optimistic than Scott’s, implying that the stone is imbued with holy light:

Gem with the burning heart,
That, as a living soul,
Pervading Every Part,
Gives beauty to the whole,
What angel’s hand thy bosom lit,
With the bright spark enkindling it.

Published in 1845, the poem illustrates opal regaining favor by mid-century. However, at the time of the Crimean War, old superstitions returned briefly when the stone was blamed for giving soldiers bad luck. In subsequent decades, attitudes warmed as more opal deposits were discovered, rekindling the opal market. This was particularly so later in the century when, in 1877, black opal was discovered in New South Wales, Australia. Queen Victoria also played a significant role in restoring opal’s reputation. She loved to wear them and was known to give them as gifts. She gifted opal jewelry to each of her five daughters as wedding presents and loved to give opal rings to many of her friends. 

In this age opals are revered once again. So long as it’s taken care of, the burning heart endures.

ALVR Blog: All Gems Are Precious

emerald and diamond ring compared with a green garnet and diamond ring to show that they are both precious gemstones

Long before we understood the chemical composition of minerals and the process of their formation, we developed stories to explain their origins, and a system of classification based on color, the most distinguishable trait. While our methods of assessing gemstones have long since evolved, one misnomer defiantly persists: the use of the terms precious and semiprecious. “Semi” is a misleading adjective, implying that these words stand in opposition to one another. We say it’s time to drop the “semi” and describe all gemstones as they are: precious.

Since the late nineteenth century only five stones have been considered “precious”: rubies, sapphires, emeralds, diamonds, and, curiously, pearl, which is not actually a stone at all. Further complicating things is the corundum conundrum, with both ruby and sapphire being variations of this stone. Corundum comes in a beautiful range of colors, which vary based on their composition. Yellow sapphire gets its hue from iron and aluminum, while purple sapphires contain chromium, titanium, and aluminum. A ruby is made up of chromium and aluminum, yet we do not call it a “red sapphire.” Blue sapphire contains titanium and iron, and is the only shade of corundum simply called “sapphire.” Also, if this isn’t confusing enough, there are also red sapphires and blue rubies.

Our understanding of corundum and its many colors has done little to change how we describe jewelry, and the false dichotomy of precious and semiprecious is just as arbitrary. In fact, the way these two terms have been defined over time lacks consistency. For example, there was once a time when the term “precious” encompassed as many as sixteen stones, including zircon, topaz, and tourmaline, recorded in the publication A Treatise on Gems from 1838. Just a few decades later, these aforementioned stones would be relegated to “semiprecious” status.

The lauded mineralogist George Frederick Kunz acknowledged the complexity of these terms in his 1890 lecture at the Franklin Institute in Philadelphia, stating that “the value of a particular kind of stone is often due in great measure to the caprice of fashion or to some adventitious circumstances of time or place.” He goes on to discuss the rising popularity of semiprecious stones in the second half of the nineteenth century aided by exhibitions, trendsetting royals, and the discovery of numerous mining deposits.

For example, the Duke of Connaught (the youngest son of Queen Victoria) chose a chrysoberyl cat’s-eye engagement ring, making this kind of stone fashionable and, as a consequence, more valuable. The search for this stone also led to the discovery of moonstone and tiger’s eye, ensuring their popularity as well. As another example, Queen Victoria’s love of opal helped revive the stone from its long bout of superstitious unpopularity.

Kunz also remarked:

“Public interest in semi-precious stones has increased greatly during the last ten years. Formerly jewelers sold only diamonds, rubies, sapphires, emeralds, pearls, garnets and agates; but at present it is not unusual to have almost any of the mineralogical gems, such as zircon, asteria or star sapphire or star ruby, tourmaline, spinel or titanite called for, not only by collectors, but by the public, whose taste has advanced in the matter of precious stones, as well as in the fine arts.”

The discovery of all these gems brought new life to jewelry design, inspiring jewelers to use them, and clients eager to wear them. While it’s been said that the jewelry industry came up with the term “semiprecious” to describe stones that were more abundant, it seems more likely it was simply intended to distinguish them from the more traditionally used stones. But this distinction wasn’t intended to have inferior implications. Kunz noted that such stones were also known as “fancy stones,” from the French phrase “pierres de fantaisie.”

Regardless of when the term originated and how it was defined, the distinction is misleading, as it implies precious gems are inherently more valuable, when a “semiprecious” stone like demantoid (green) garnet can be worth more than an emerald. They are both green, yet one is “only” a garnet. We say both are equally precious! The same can be said of a river pebble mounted in gold, transformed into a fine jewel as precious as a ruby, emerald, or… a green garnet! A gem is a gem is a gem, and we firmly believe you should choose the jewel that makes you smile, whether it’s a multi-color natural zircon necklace, or an old-mine diamond rivière. All gems are precious.

Cocktail Rings – Glitter on the Rocks with a Twist

0

Prohibition era (1920-1933) cocktail parties rekindled a love for statement jewelry as part of a new genre of festive adornment consisting of cocktail dresses, aprons, hats, and, of course, flashy cocktail rings. Our collection includes a range of examples from the Art Deco era to the later twentieth century. The taste for these party rings continues on today, often as a favorite accessory on the red carpet.

Fancy Sapphire Ring

 

Women attending cocktail parties showed off the new fashions, and in doing so, their newfound liberties. Often bought by a woman for herself, cocktail rings were a testament to a woman’s increasing autonomy and individuality.  One can easily imagine an elegant, au courant lady tapping her glass while wearing our Art Deco diamond and sapphire pinky ring. An oversized cocktail pinky ring such as this could easily be worn on either the right or left hand.

Ruby, Diamond, and Platinum Art Deco Ring

Our 1930’s diamond cocktail ring in the form of a shield with a ruby in the center reflects the predominant taste for ‘white’ jewelry – the effect of diamonds on platinum, but the central ruby adds just a touch of flare.

Black Opal Ring

Our 1950’s black opal and diamond cocktail ring makes quite the statement. The oblong form of the ring is well suited to be worn on the pointer finger and could never be confused with one intended to signify betrothal.

Cartier Bombé Ring

Our 1960’s diamond bombe ring embodies Cartier’s assurance as a seasoned jewelry house in both their designs and materials. The oversized diamond ring has over 12 carats worth of diamonds but it is more than just a display of intrinsic value – the traditional bombé form is elevated by the subtle striping of the princess and round-cut diamonds.

The cocktail ring transformed over the decades into the perfect statement piece suitable for all occasions. We have many styles to choose from, everything from aquamarines to entirely diamond rings. Please feel free to either come by the gallery to see our entire selection or email us!

Taking Liberties with Arts and Crafts Jewelry

Knox Arts and Crafts Necklace

The necklace pictured is from the ‘Cymric’ line of jewelry sold at the London retailer and design firm Liberty & Co.  ‘Cymric’ jewelry capitalized on the aesthetics of the Arts and Crafts movement, but disregarded most of its founding principles.

Liberty & Co. aided in spreading the Arts and Crafts jewelry style across greater echelons of British society. Launched in 1899, the ‘Cymric’ line featured the typical characteristics of Arts and Crafts movement jewelry and appeared to be handmade, but was actually mass-produced. While some details still required hand finishing, cheaper machine processes were used whenever possible. Manufactured by Haseler of Birmingham, these high quality pieces were a fraction of the cost of their handmade Arts and Crafts equivalents.

Much of the line’s success can be attributed to the painter, teacher and designer of jewelry and metalwork, Archibald Knox (1864-1933). From 1897 to 1912 Knox designed not only jewelry but also a wide array of silver, pewter, carpets and textile designs for Liberty. As Liberty’s chief designer, Knox infused the Arts and Crafts aesthetic with Celtic inspiration from his native Isle of Man. His elegant adaptation of Celtic interlace became one of the most distinctive characteristics of the line. ‘Cymric’ jewels were produced in both gold and silver and often set with turquoise, blister pearl or mother-of-pearl or decorated with enamel. This blister pearl, opal and gold necklace ca. 1900, designed by Archibald Knox for Liberty and Co. illustrates many of the key characteristics, materials and techniques found within the ‘Cymric’ line of jewelry.

The chain and gold pendants on this delicate necklace were mass produced, while the setting of the opals as well as the pearls required expert hand finishing. Though not entirely handcrafted, the integrity of the design attests to the clever hand of its creator.
