What happens when sliced stone becomes a kaleidoscope? ✨

During our May 2025 visit to Idar-Oberstein, I photographed these imaginative works associated with Manfred Wild and Emil Becker KG: where stone, metal, and color become sculpture and visual storytelling.

The large kaleidoscope is assembled from slices of stone. Its circular design and changing colors come from the natural patterns and varied colors revealed when the stone is sliced. The same creative approach appears in the ornate gemstone-and-metal box, the salamander, created as a reverse intaglio painting, and the seal figure supporting a blue enamelled egg.

These works reflect Idar-Oberstein’s long gemstone tradition. The official Emil Becker history traces gemstone processing in the Becker and Wild families back to 1630 and notes that Manfred Wild began his gemstone career in 1960 and, with his wife Ute, continued Emil Becker from 1970.

Manfred Wild’s work reminds us that gemology is not limited to identifying and grading finished stones. Minerals can also become sculpture, architecture, movement, and story.

How small can a world become: and still feel monumental? 💎

During my week in Idar-Oberstein in May 2025, I visited Emil Becker KG and explored the imaginative, technically ambitious gemstone art associated with Manfred Wild.

The miniature railway landscape is a remarkable example: tiny trains, houses, tracks, scenery, and mineral details: all crafted from stones and gold: are brought together as an intricate model world: then elevated into an objet d’art.

That same spirit appears throughout the surrounding works: carved flowers and leaves, a vivid blue fish rising from a mineral form, and a finely detailed sailing ship that demonstrates the patience and precision behind gemstone art.

Based in Kirschweiler near Idar-Oberstein, Emil Becker KG traces its Becker and Wild family gemstone-processing tradition to 1630. Its creations bring together lapidary, engraving, goldsmithing, and enamelling in imaginative one-of-a-kind objects.

What happens when gemstone artistry sails beyond conventional jewelry? ⛵️

During my week in Idar-Oberstein in May 2025, I photographed this Gorch Fock model during my visit to Manfred Wild/Emil Becker in Kirschweiler.

The fine rigging, sails, metalwork, and gemstone elements demonstrate the extraordinary scale and precision of Manfred Wild’s objets d’art. This piece includes an agate cameo, and the Gorch Fock ship is made with gold and rock crystal, showing how his work extends gemstone artistry beyond conventional jewelry.

The photos also includes an agate carving of the Last Supper, where a natural feature of the stone appears as a lighted area on Jesus.

The Gorch Fock is a striking example of how gem materials can become part of a larger artistic vision: one that combines observation, craftsmanship, and remarkable attention to detail.

What happens when gemstones become works of art rather than simply objects to admire? ✨

During my week in Idar-Oberstein in May 2025, I had the opportunity to view gemstone and precious-metal objects associated with Manfred Wild and Emil Becker KG in Kirschweiler.

The photographs in this carousel show a selection of the gemstone and precious-metal art objects I viewed, including detailed nature-inspired and animal forms and elaborate constructed objects.

Manfred Wild is an important gemstone artist whose work brings together cutting, carving, goldsmithing, and enameling. The photographed pieces reflect an extraordinary combination of sculptural imagination, precious materials, and meticulous design: from natural forms and animals to elaborate mechanical and architectural objects.

The tradition behind this work is equally remarkable. According to the official Emil Becker website, the Becker/Wild tradition reaches back to 1630. Manfred Wild began his gemstone career in 1960 and continued Emil Becker with his wife, Ute, from 1970.

This history helps place the objects in context: they are not simply decorative pieces, but part of a long Idar-Oberstein tradition in which gem materials, artistic vision, and fine metalwork come together.

We are thrilled to welcome an esteemed panel of judges for this year's competition, which promises to find some exceptional photomicrographs by established and emerging talents in our global gemmology community.

💎 Muhammad Ayub is a gemmologist, gemstone dealer and award-winning photomicrographer based in Bangkok, Thailand.

Growing up near Pakistan’s renowned Katlang pink topaz deposits and close to the emerald-producing Swat Valley, he developed an early fascination with gemstones and mineral specimens. He later moved to Bangkok, where he established Pretty Little Gem Co., Ltd. and earned the Accredited Gemologist (A.G.) diploma from the Asian Institute of Gemological Sciences (AIGS). He is also an Accredited Senior Gemologist and Lifetime Voting Member of the Accredited Gemologists Association (AGA).

💎 Keith Chow FGA graduated from the Gemmological Association of Great Britain (Gem-A) in 2021. He has worked as a gemmologist at Gübelin Gem Lab for the past five years, at both the Hong Kong and the New York locations. There, he has received extensive training in the observation and identification of gemstone inclusions.

Through this identifying and documenting of inclusions as part of his laboratory work, Keith developed a particular passion for photomicrography. His inclusion photography was awarded first and third place in the Gem-A’s Photographer of the Year 2025 competition and made the longlist of the 2024 competition.

💎 Melissa Scarani FGA ASA GG discovered a particular fascination with what can be found inside a gemstone from the moment she opened her first Photoatlas of Inclusions. This early inspiration set her on a path toward becoming a dedicated gemstone photomicrographer.

Continuing my Idar-Oberstein series with a visit to Wild & Petsch GmbH in Kirschweiler, just outside Idar-Oberstein, during my week in the region in May 2025. 💎

Wild & Petsch traces its gemstone-cutting tradition back to 1901. The current company was formed in 2001 when the cutting businesses of Karl-Egon Wild and Thomas Petsch merged, as reported by JCK at the time. Today, Wild & Petsch is recognized for the precision cutting and processing of colored gemstones.

In one photograph, I am holding two Brazilian Paraíba tourmalines. According to Wild & Petsch, the darker marquise is unheated and the bright neon round is heated. Color alone should never be used to determine treatment, but seeing the two side by side is a striking example of how heating can change appearance. Treatment status can influence identification, rarity, market value, and how a gemstone must be described in an appraisal. Accurate disclosure is at the heart of every appraisal.

It was a pleasure to spend the visit examining stones with Tapio of Magilabs, and yes, the matching plaid was completely unplanned. I also loved photographing the stunning tourmaline stained-glass door at the entrance, a beautiful detail that reflects the character of this historic gemstone center.

Thank you to Wild & Petsch GmbH for welcoming us, and for being part of the remarkable gemological story of the Idar-Oberstein region. Learn more at https://www.wildpetsch.com/ and connect with them on LinkedIn: https://www.linkedin.com/company/wild-petsch-gmbh ✨

Idar-Oberstein: A Visit to Constantin Wild 💎

During our week in Idar-Oberstein, we visited Constantin Wild, a historic gemstone house whose story traces back to 1847, when Johann Carl Wild founded the company. Constantin Wild describes the business as a legacy spanning ten generations, a rare thread of continuity in the world of exceptional gemstones.

Today, Constantin Wild leads the company as its tenth-generation leader, overseeing sourcing, cutting, and sales, including cutting and recutting gemstones at its own domestic facility.

During our visit, we saw the mineral storage room, the historic gemstone collection, the workshop spaces, and the Gem Room, which showcases exceptional gemstones and suites. Each space offered a different perspective on Idar-Oberstein's long tradition as a center for exceptional gemstones and suites.

Thank you to Constantin Wild and his nephew Friedrich Wild, now part of the Wild team, and to the entire Constantin Wild team, for generously sharing your work, your collections, and your history with us. It was an honor to see this legacy up close.

How does a gemstone become a one-of-a-kind work of art? 💎 During our time in Idar-Oberstein, we spent half a day at Lorenz Gravuren, learning about their process of gemstone engraving and fine carving.

The studio specializes in fine engravings and signet rings, with each piece carved by hand, no mechanical reproduction. Watching the engravers work, what stood out most was the precision: steady hand control and controlled tool movement translating directly into fine detail, piece by piece.

Two carvings in particular were remarkable: a carved Joker and a carved Jimi Hendrix. On close inspection, the tip of Hendrix's cigarette is set with an opal, cut and placed to simulate a burning ember. 🔥

Lorenz Gravuren was founded on September 1, 1969, by Hans-Peter Lorenz. Today, his sons Oliver and Christian Lorenz, both trained gemstone engravers in their own right, lead the studio together, continuing a craft that has now passed across generations.

Our thanks to the Lorenz team for their generosity in sharing their work and process with us. For those in the trade, their work is worth a visit: .

Idar-Oberstein: The Beating Heart of the Gemstone World 🇩🇪💎

Last year we took a deep dive into Idar-Oberstein, Germany, for the 50th Anniversary D-Gem Conference. Walking through these historic streets, it's impossible not to feel the weight of centuries of gemstone cutting heritage.

From scientific sessions at the DGemG Training Centre to visits inside local homes and family workshops, this trip was more than a professional milestone. It's part of the foundation of our expertise at Gemology Resources.

To provide a fair, precise valuation, you have to understand the market. You have to stand at the wheel where the stone was cut and speak with the artisans who've passed these techniques down for generations.

Over the next few weeks, I'll be sharing a series of boots-on-the-ground stories from the trip, from the cutting-edge science of the conference to the old-world craftsmanship of the workshops. Stay tuned for a behind-the-scenes look at the people and traditions that define the world's gemstone capital. 🔎

Why is my jewelry worth different prices?

It’s a question that catches many collectors off guard, but the answer is simple: The value of a piece isn't a fixed number: it depends entirely on the purpose of the valuation.

Whether you are insuring a new heirloom or settling an estate, using the wrong value type can lead to complications. Here are the four of the main value types we use at Gemology Resources:

Retail Replacement Value (RRV): The standard for insurance. This reflects the cost to replace the item with a brand-new equivalent in today’s retail market.

Fair Market Value (FMV): The IRS standard for estates and donations. This is the price at which an item would change hands between a willing buyer and a willing seller.

Liquidation Value: The estimated amount realized in a fast-sale or "forced" scenario.

Cash Value: The amount of immediate cash the item would bring in today’s market.

With over 25 years of experience and ASA (American Society of Appraisers) credentials, I ensure your appraisal follows the correct legal and professional standards for your specific needs. Accuracy isn't just about a number; it’s about the right context.
