Electroformed GOLD Bracelet
GIA has provided a service for validating mounted gemstones in jewellery for decades. Recently, these services have been expanded to include precious metal items (rings, necklaces, and bracelets) to ensure their authenticity and ensure the metal is as stated. The service is intended to protect both buyer and seller.
As part of this service, a gold bracelet measuring 8 inches in circumference and 1.25 inches wide and weighing 41 g was recently examined in the Carlsbad laboratory (figure 1). It was submitted as 14K solid gold, but initial observations raised suspicion. The bracelet felt too light and almost hollow, and there was a significant contrast in textures: a matte finish on the inside surface of the bracelet compared with the wavy, shiny exterior surface. The bracelet had a 14K hallmark, which appeared to be stamped or engraved onto a different metal piece that was glued or otherwise adhered to the bracelet (figure 2).
X-ray fluorescence (XRF) analysis of the shiny exterior surface gave a result of 17.99K gold, and no subsurface material was detected that would indicate plating. Additional testing of another smooth surface yielded a result of 22.47K. Further analysis under brighter lighting conditions revealed areas where gold plating had flaked off from the piece (figure 3). We believe this wavy texture of the gold was used intentionally to hide the poor quality of the finish and the flaking gold plating, as shadows can often mask imperfections on initial sight.
A wax or resin material was observed under the plating, and we concluded that the bracelet had been created using electrodeposition to electroform the piece. Electroforming is a method of adding a thick gold plating, sometimes as thick as 200 microns, to a wax, resin, ceramic, or organic material base. Thick plating and electroforming may not be detected by XRF methods alone, and additional testing may be necessary to detect the application of these processes. We believe this wax- or resin-filled electroformed bracelet was being sold as solid 14K gold with the intention to deceive the buyer. This example demonstrates the importance of testing and verification services such as GIA’s jewelry verification service.

Artisan Perspectives: Rethinking Craft In The Age Of Lab-Grown Stones
Prapanjj S K Kota
Founder & CEO at Réia Diamonds
- Traditionally, diamond value was driven by rarity, origin, and size, with craftsmanship playing a secondary role.
- With the rise of lab-grown diamonds, abundance is shifting focus from rarity to design and craftsmanship.
- Jewellery-making is returning to a craft-first approach, placing artisans at the core of value creation.
- Skill, precision, and finishing quality are becoming primary differentiators.
The rarity of diamonds has historically dictated their market value, and most of the conversation surrounding a diamond’s value has revolved around where (and how rare) it came from, and how large it was. While craftsmanship has always been important, it has often remained secondary, simply supporting the diamond rather than receiving the buyer’s focus.
As lab-grown diamonds begin to enter the market in greater numbers, the conversation surrounding them is also changing. With an increasing supply of diamonds, being a differentiating factor in jewellery becomes much more about design, craftsmanship, and the quality of work than about rarity.
For artisans, this shift means that the focus of making jewellery has returned to the craft itself.
From a technical perspective, lab-grown diamonds do not affect the fundamentals of jewellery making. They will continue to have the same hardness, brilliance, and structural properties that natural diamonds do; therefore, using traditional setting techniques, including precision settings, pavé work, micro-setting, and polishing, will be just as essential. While the tools may be more modern, the knowledge to work with diamonds continues to be based on many years of training and experience.
The major change comes with the new opportunities presented by working with lab-created stones.




Designers are utilising the increased access to stones to try new layouts incorporating a greater focus on symmetry, scale and intricate detail. As jewellery changes, so does its craftsmanship. Today, with designs that involve numerous stones, layered settings, and modern silhouettes, artisans must have an intentional focus on the structural integrity and balance of the pieces being created, elevating their role more than ever before.
As we see craftsmanship play a supporting role to design when jewellery becomes design-centric, the specifics of how stones are aligned, how strong the setting is, and how well metal surfaces are finished will have an impact on how a piece looks, feels, and holds up over time; and therefore, they cannot be replicated with technology alone.
This change also highlights the importance of India’s historical craft traditions. Surat’s experience in the production of diamonds has established it as a leading force in the world of fine jewellery. This industry relies heavily on a team of talented craftsmen and manufacturing expertise, which plays a very important role in the overall development of jewellery that uses natural as well as lab-grown diamonds.




The introduction of lab-grown diamonds offers a fresh new direction for many artisans, as well as introducing something new into the world of fine jewellery. As it becomes less critical to know where a stone comes from, knowing the quality of the craftsmanship around a piece of jewellery will become increasingly essential. Design integrity, structural engineering, and finishing standards will all contribute to defining the real value of a finished piece.
Therefore, there is an opportunity for artisans; thoughtful design with precise execution requires a high level of technical proficiency. The better the craft, the more evident the difference is.
With the rise of lab-grown diamonds, the discussion about value will slowly evolve to include what has always been considered great jewellery: the skill, time, and craftsmanship it takes to create a piece of art from a design.
