Cabochon turquoise is a specific form of the beautiful turquoise gemstone that has been crafted in a particular way to showcase its unique qualities. It’s a popular choice in jewelry making and has a distinct appearance and set of characteristics. In this article, we’ll explore what cabochon turquoise is, how it’s made, its uses, and what makes it so special in the world of gemstones and adornments.
Definition and Basics
What is a Cabochon?
A cabochon is a gemstone that has been shaped and polished into a rounded, convex form without facets. Unlike faceted gemstones that have multiple flat, cut surfaces to reflect light and create sparkle, a cabochon has a smooth, domed top and a flat or sometimes slightly curved bottom.
The process of creating a cabochon focuses on enhancing the natural color and texture of the gemstone rather than maximizing its brilliance through faceting.
Cabochon Turquoise Specifically
Cabochon turquoise, then, is turquoise that has been cut and polished into this characteristic cabochon shape. It retains the natural beauty of the turquoise, with its captivating blue-green hues and any unique matrix or veining that might be present within the stone.
The domed shape gives it a soft, elegant look and allows the light to play across its surface in a way that highlights its color and luster, creating a more subdued yet alluring visual effect compared to faceted stones.
The Cutting and Polishing Process
Selecting the Rough Turquoise
The first step in creating cabochon turquoise is choosing the right piece of rough turquoise. Gem cutters look for stones that have good color, minimal internal flaws that could affect the final appearance, and an interesting matrix if desired.
For example, a piece of rough turquoise with a beautiful sky-blue color and a unique spiderweb-like matrix might be selected for making a particularly eye-catching cabochon.
Shaping
Once the rough turquoise is chosen, it’s then cut to remove any excess material and to start forming the basic rounded shape. This is usually done using lapidary equipment like saws and grinders. The cutter carefully works the stone to create a symmetrical and pleasing dome shape on the top.
It’s important to maintain a consistent curve and thickness throughout the cabochon to ensure its durability and aesthetic appeal. Depending on the size and design goals, the cabochon can range from a small, delicate shape to a larger, more substantial one.
Polishing
After shaping, the cabochon goes through a polishing process. Special polishing compounds and wheels are used to give the surface of the turquoise a smooth and shiny finish. This step brings out the true color of the stone and enhances its natural luster.
The polishing is done carefully to avoid scratching or damaging the relatively soft turquoise. It can take time and skill to achieve a perfect polish that makes the cabochon look its best and ready for use in jewelry or other decorative items.
Characteristics of Cabochon Turquoise
Appearance
Cabochon turquoise has a distinct visual appeal. Its rounded shape gives it a soft, organic look that is often associated with a more natural and earthy aesthetic. The color, which can range from vivid blues to greenish-blues, is showcased in a way that makes it seem almost luminous when light hits it from different angles.
The presence of a matrix, if there is one, adds to its charm. A matrix might look like delicate veins or patterns running through the stone, and in cabochon form, it becomes an integral part of the overall design, telling a story of the stone’s origin and formation.
Durability
While turquoise in general is a relatively soft gemstone with a hardness ranging from 5 to 6 on the Mohs scale, when cut into a cabochon, it can still be durable enough for use in certain types of jewelry. The domed shape doesn’t have sharp edges or corners that are prone to chipping easily.
However, it’s still important to handle cabochon turquoise with care as it can be scratched by harder materials. For example, it should be kept away from other jewelry pieces when stored to prevent scratches during contact.
Luster
Cabochon turquoise has a unique luster that is different from faceted gemstones. Instead of the intense sparkle created by facets, it has a more satin-like or vitreous luster. This gives it a smooth, almost silky appearance when polished, and the light reflects off it in a gentle, diffused way that adds to its overall allure.
Uses in Jewelry
Necklaces
Cabochon turquoise is a popular choice for necklaces. A single large cabochon set in a simple metal pendant and hung on a chain can make for an elegant and eye-catching piece. It can be the focal point of the necklace, drawing attention with its color and shape.
Alternatively, multiple smaller cabochons can be strung together with other beads or gemstones to create a more elaborate and textured necklace. For example, combining cabochon turquoise with coral beads or silver spacers can result in a beautiful and unique design that’s suitable for both casual and formal occasions.
Bracelets
In bracelets, cabochon turquoise can be used in a variety of ways. It can be set into a metal cuff bracelet, with the cabochon adding a touch of color and sophistication to the bold metal design. Or, it can be part of a beaded bracelet, where the cabochons are threaded onto a cord or wire along with other complementary beads.
The rounded shape of the cabochons makes them comfortable to wear on the wrist and gives the bracelet a flowing, organic look.
Rings
Rings featuring cabochon turquoise are quite striking. The cabochon can be set as the centerpiece of the ring, either in a bezel setting that completely encircles the stone for added protection or in a prong setting that allows more of the stone to be visible from the sides.
A ring with a large cabochon turquoise can make a bold statement, while smaller cabochon accents on a ring can add a delicate and charming touch.
Earrings
Cabochon turquoise earrings come in many styles. Drop earrings with cabochon turquoise dangling from a metal hook can add movement and elegance to an outfit. Stud earrings with small cabochons are simple yet stylish and are perfect for everyday wear.
Hoops can also incorporate cabochon turquoise, either by having the cabochons set along the hoop or at the bottom for a more eye-catching effect.
Value and Quality Factors
Color
The color of cabochon turquoise plays a significant role in determining its value. A vivid, intense blue color is often the most prized, similar to what’s known as “Persian blue.” Stones with a more greenish tint or those that are paler in color are generally considered of lower quality and value.
However, some collectors might appreciate unique color variations or a particular blend of blue and green that gives the cabochon a special character.
Matrix
The presence and quality of the matrix also affect value. A well-defined, attractive matrix that enhances the overall look of the cabochon can add to its desirability. For example, a matrix that forms a beautiful pattern, like a spiderweb or intricate veining, can make the cabochon more sought-after.
On the other hand, a matrix that is too messy or detracts from the color and clarity of the turquoise might lower its value.
Size
Larger cabochon turquoise pieces are generally rarer and, therefore, more valuable. However, size alone doesn’t determine quality. A smaller cabochon with exceptional color and a perfect shape can still be highly prized, especially if it’s intended for use in a delicate and refined jewelry piece.
How to Care for Cabochon Turquoise Jewelry
Cleaning
To clean cabochon turquoise jewelry, use a soft, damp cloth to gently wipe away any dirt or oils that may have accumulated on the surface. Avoid using harsh chemicals or abrasive cleaners as they can damage the stone.
If needed, a mild soap solution can be used with a soft brush, like a baby toothbrush, to carefully clean the crevices around the cabochon, but make sure to rinse it thoroughly with clean water and pat it dry with a soft cloth afterward.
Storage
When not wearing cabochon turquoise jewelry, store it in a separate compartment or a soft pouch to prevent it from rubbing against other jewelry pieces and getting scratched. Keep it in a cool, dry place away from direct sunlight, as prolonged exposure to sunlight can fade the color of the turquoise over time.
Conclusion
In conclusion, cabochon turquoise is a remarkable form of the turquoise gemstone that offers a unique combination of beauty, durability (within its limits), and versatility in jewelry making. Its distinct shape, the way it showcases the natural characteristics of turquoise, and its wide range of uses make it a beloved choice for jewelers and jewelry enthusiasts alike. Understanding what cabochon turquoise is and how to care for it allows us to fully appreciate and enjoy this beautiful gemstone in our adornments for years to come.
