  • Warning Signs Your Fine Jewelry Needs Some TLC, Quick!


    Anyone who discovers a treasured jewelry item they were wearing has suddenly disappeared knows that awful, sinking feeling you get and the mad scramble that ensues looking everywhere possible to find it.

    Fine jewelry, like a fine automobile, requires periodic maintenance. And just like there are warning signs of car trouble, so are there warning signs of wear and tear with your jewelry. Tell-tale signs indicate you may be in danger of losing a precious stone or losing your jewelry item altogether.

    Jim is known for saying in jest, “If you never wear your jewelry, you will never have a problem with it.” But as we all know, jewelry is meant to be worn and enjoyed! So, with care, the knowledge of a few warning signs and a slightly trained eye, preventable losses can be minimized enabling you to enjoy your jewelry for years to come.

    Here’s what to look for:

    • Damaged prongs & channels - Notice the condition of the prongs or channels holding in the stones. Prongs should be adequately covering the edge of the stone. If they are shorter than others, too thin or bent, the prongs may be in danger of breaking. Channels should also not be too thin and have ample metal holding the stones.
    • Loose stone - If you notice a stone has shifted in its position, is no longer level, or jiggles when tapped, the prongs are no longer holding the stone tightly enough.
    • Difficult clasps - Any time you are struggling with a clasp, whether it closes too tightly or doesn’t close tightly enough, there is a risk of damage to or loss of the item.
    • Damaged earring posts - A Wobbly, broken or bent earring post affects the integrity of the earring back as well as the post itself.
    • Stretched out pearl necklace or bracelet strands – Pearl necklaces and bracelets, over time, may begin to stretch out and be in danger of breaking. Re-stringing should be considered if the strand begins to hang lower, is showing visible gaps between the pearls, or you see visible fraying of the threads.

    If you notice any damage or wear and tear to your fine jewelry, be sure to get it checked out as soon as possible. The sooner an issue is identified, the easier and less costly it will be to fix.

    Jessop’s is always happy to inspect your fine jewelry and sparkle it up with a deep cleaning. It is advisable to have this done at least once a year, particularly for pieces you are wearing on a daily basis. If we identify any problem areas, we will make a recommendation and provide an estimate for the repairs.

  • The Perfect Diamond - A Cut Above the Rest


    Carat weight, color, clarity, and cut of a stone (the 4 C’s) will determine the value of a diamond, as well as its appearance. Of the 4 C’s, cut quality is most important. The cut does not refer to the shape of the diamond, (like marquise or emerald), or the facet style, (like step or brilliant cut), but refers to the diamond cutter’s skill at cutting to optimally make the diamond as brilliant as possible. It is the cut that brings an otherwise lifeless raw stone to life; it’s what determines the level of sparkle and brilliance seen emanating from the diamond.

    = Ray of Light

    2SHALLOW CUT – Light escapes through the bottom before it can be reflected back up through the top.

    DEEP CUT – Light escapes through the sides.

    EXCELLENT / IDEAL CUT – Light is internally reflected from one facet to another until it shines back up through the top giving off the highest possible brilliance.

    An excellent cut diamond is cut to mathematical precision, providing the best possible optics in the arrangement of facets. This allows for light entering the top of the diamond to be directed through the gem and reflecting to achieve maximum brilliance. A diamond may be the carat weight, color, and clarity you desire, but without high marks for cut quality, it will lack the brilliance, the sparkle, you may see in another similar diamond. A diamond cut too shallow or too deep may have a larger diameter and appear to look bigger, but a well-cut diamond of high brilliance will be more beautiful.

    We are diamond experts at Jessop Jeweler. Whether purchasing your first diamond or next diamond, we will give you the knowledge to understand and be confident of your diamond choice.

  • Rings & Rashes – A Simple Solution to a Common Problem

    Occasionally, we are asked about what to do if a rash occurs under a wedding band or diamond ring. Often times, the individual might suspect they are allergic to the metal, which can happen, but usually it can be solved with a simple solution, literally.

    Rashes can be caused by an allergy, such as nickel (an alloy in white gold), or possibly by something that has changed with your body. Are you using a different soap or hand lotion? Body chemical changes can have an effect too, such as childbirth, a change in diet, or a change in drugs you are taking.

    Most likely over time and wear, you have accumulated some type of irritant under your ring. Perhaps soap was not completely rinsed from under the ring when washing your hands. Or, something harsh has soaked into soil accumulated under the ring. The irritant or soap sits against your skin and burns the skin. Once the skin is damaged, any little thing may cause it to be worse. By following the steps below, common ring rashes can be cleared and avoided in the future.

    STEP ONE - Remove your ring, apply steroid cream on the rash (like Cortizone 10), and let your finger heal completely before wearing the ring again.

    STEP TWO - (Only for jewelry consisting of gold, platinum, diamonds, sapphires, or rubies. This would be damaging to other stones, metals, or costume jewelry)

    Take a glass bowl of water mixed with a little dish soap (like you are washing your dishes) and add a teaspoon of ammonia. Be cautious, as the ammonia fumes are strong. Microwave the solution until too hot to touch. Remove from the microwave, submerge the ring, and let it soak as the water cools off for 30 to 60 minutes. **Never place your ring in a pan on the stove to heat it. We’ve had people who did this forget about it and extreme damage has occurred to the pan and the jewelry.

    STEP THREE - Take a child sized SOFT bristle toothbrush and scrub the ring, top, bottom, and sides. If necessary, re-soak the ring and brush again until the ring is spotless and any possible irritant is removed. Do a final brushing under running, clear, warm water and then dry thoroughly.

    When you start wearing the ring again, take extra care when washing your hands to rinse the underside of the ring where it touches your finger.

  • Women's Necklace Lengths - What's the Hang Up?

    Choosing the right necklace length will add the right finishing touch and style to your outfits and make you feel confident about this fashionable investment.


    This chart represents the average woman’s height and neck measurements. Keep in mind that a 20” necklace, for example, may hang like a 24” necklace on a petite frame or may hang like an 18” necklace on a larger frame, so take this into account.

    Women up to 5’4” look best in lengths from 14” to 20”
    Women 5’4” – 5’7” can pull off any length,
    Women 5’7” and taller can also wear any length, especially longer styles that complement their tall stature.

  • SPINEL (spin-l) - Now an August Birthstone

    Jessop ‘s One-of-a-Kind Red Spinel & Diamond Ring - SHOP HERE!

    For centuries, many gemstones thought to be rubies used in crown jewels throughout the world actually turned out to be spinel. This initial confusion resulted from spinel’s resemblance to well-known stones like rubies or sapphires.

    Spinel’s beauty and wide range of colors and cuts makes it deserving of appreciation and recognition in its own right. Designating spinel as an August birthstone is further proof of its importance in the gem world.

    The most desirable and valuable spinel gemstones are vivid red, followed by cobalt blue, bright pink and bright orange. Vividly colored spinel gemstones are rare in sizes over 5 carats. Paler colors tend to be more affordable. Other colors found are black, violet-blue, greenish-blue, pale-pink, mauve, yellow and brown.

    A good quality stone should have no visible inclusions; the more inclusions, the less valuable the stone. However, a rare but desirable inclusion would result in a star spinel. Spinel ranks 8 on the Mohs scale and has good toughness, making it a durable gem for jewelry.

  • Retro Modern Jewelry (~1935 to 1950)

    During the 1930’s, Art Deco jewelry designs began to evolve into geometric styles that were larger and more heavily proportioned and curvaceous. This became known as Retro Modern. Floral motifs from the romantic, Victorian period were boldly reinterpreted, while other designs were modern and geometric. As the 1940’s rolled around, the Hollywood scene and World War II influences were making an impact on not only jewelry design, but on the materials used and the type of pieces women would wear.

    During World War II, platinum was considered a strategic material reserved primarily for military applications. Therefore, with the greater availability of gold, copper, and other alloys, highly polished yellow, rose, and tricolor gold took over in popularity. As precious stones were scarcer to come by, less costly yet beautiful colored stones, such as amethyst, citrine, aquamarine, tourmaline, topaz, and gems from South America were used. Three dimensional, lavishly embellished, ribbon and bow, scrolled, and scalloped design elements were common along with the use of baguette diamonds.

    Also at this time, the Golden Age of Hollywood was in full swing and fully embraced and influenced Retro Modern jewelry. People looked to the silver screen for fashion cues and women wanted to emulate the female stars and their glamorous, colorful, over-the-top style.

    Female wartime clothing fashions were more masculine in design, utilizing heavy fabrics and featuring broad shoulders and wide lapels. The heavy fabrics needed something to provide a softer, feminine touch. Brooches became the most popular jewelry pieces worn as the wide lapels were the perfect place to display these big, bold fashion statements. Another popular item worn was elaborate rings of precious stones with shapes and curves that rose up high on the finger.

    The influential Retro Modern jewelers were Trabert & Hoeffer-Mauboussin, Van Cleef & Arpels, Tiffany & Co, Boucheron, Cartier, Fulco di Verdura, Raymond Yard, Paul Flato, and Guberlin.

  • Art Deco Jewelry (~1910 to 1935)

    By the mid-1920’s, the Art Deco movement in jewelry had taken over the curving, free-flowing, organic, and subdued colors of the Art Nouveau period. Art Deco design was more sculptural and dramatic by using bold colors and geometric shapes often with sharp angles.


    In 1925, the Exposition des Arts Décoratifs et Industriels Modernes was held in Paris. The Exposition was dedicated to the display of modern decorative arts of that time and is where the term Art Deco was coined. Designs were influenced by the pure geometric forms found in Cubist movement artwork and by the shapes, structural characteristics, and highly polished surfaces of industrial machinery. Artisans drew inspiration from the esthetics of gears, cogs, wheels, and forms of modern transportation such as trains, planes, and automobiles. They interpreted these forms in streamlined and minimalist ways. Even the nature motifs of flowers, birds, and animals prevalent in Art Nouveau design took on a new stylized geometric appearance during the Art Deco period.

    Several style elements began to emerge in jewelry design as a result. White metals of silver, white gold, and platinum replicated the metallic sheen of the industrial look. Bold black and white jewelry became popular and appealed to the modern, independent woman. Materials often used included black onyx, black enamel, pale chalcedony, rock crystals, and diamonds. New diamond cutting techniques introduced rectangles, baguettes, triangles, and half-rounds that worked well in geometric combination and could be used to add sparkle, dimension, and texture without adding color.


    Art Deco designers, such as Cartier and Van Cleef & Arpels, borrowed stylistic elements found in eastern cultures and other exotic influences. The colorful costumes and stage backdrops from the Ballet Russes inspired bold color choices. Chinese and Egyptian motifs were often present. Therefore, a wider variety of less costly gemstones were valued and primarily chosen for their color, texture and translucency, often paired with precious stones in new, dramatic combinations. A greater use of colored jade, turquoise, lapis lazuli, coral, and colored enamels was evident. Black enamel was particularly important.

    The Art Deco period has remained a very distinct and popular style period. The prominent and influential jewelers include Jean Fouquet, Gérard Sandoz, Raymond Templier, Cartier, and Jean Després.

  • Jewelry from the Art Nouveau Period (~1895–1910)

    The Art Nouveau movement first began with a group of French designers who took a more artistic approach to their unique, one-of-a-kind jewelry designs. Previously, jewelers were seen more as craftsman who created traditional platinum jewelry settings as a way to mount and showcase diamonds and other precious stones used in the piece.

    Screen Shot 2016-06-27 at 11.43.43 AM

    During the Art Nouveau period, jewelers worked more as artisans who designed and created “works of art” often in gold or silver that were then enhanced and complimented with colored semi-precious gemstones like turquoise, opal, and moonstone. There was also a comeback in skilled enameling techniques. In plique-a-jour, unbacked wirework was filled with transparent enamel, resulting in a stained-glass effect. Cloisonné enamelwork involved areas separated by thin metal compartments filled with colored enamels.

    Designs were also inspired by the natural world and the female figure. Common motifs were flowers, leaves, and insects, especially the dragonfly. Sometimes fantasy images were used by combining nature with the female form, like butterfly wings on a woman’s body or a woman’s head with a plant body. Colors were soft and pastel and the designs were curved and free-flowing.

    Some of the important jewelers during this time were René Lalique, Louis Comfort Tiffany, Georges Fouquet, Lucien Gaillard, Henri Vever, and Gérard Sandoz.
