Inside Our Workshop: How Kesardeep Ensures 92.5 Sterling Silver Purity

When it's time to create pieces of silver that stand the test of time, quality is not a decision; it is a commitment. Kesardeep.co was built on that commitment. As a trusted manufacturer of silver jewellery in Jaipur, we pride ourselves on offering silver jewelry that offers authenticity, craftsmanship, and value based on tradition, technology, and trust.

But what happens before it reaches the customer? Let's take you inside of our workshop where 925 sterling silver purity is neither a guideline nor a principle; it is a vow.

The Legacy of Sterling Silver

Before diving into the technicalities, we want to take a moment to clarify that we are on the same wavelength in terms of what 925 sterling

silver actually is. Pure silver is too malleable to make jewelry from, so instead, an additional 7.5% of metals—most commonly copper—are alloyed into silver for durability. This alloying creates the balance of 92.5% pure silver, which is what is termed "sterling silver. This standard is recognized globally in the jewelry industry.

At Kesardeep, we have established processes for each piece of jewelry that uphold the international quality standard of sterling silver.

Step 1: Responsible Sourcing of Raw Material

Every beautiful piece begins with the right raw material. We source silver from government-accredited and ethically sourced suppliers where the silver content meets the quality levels expected internationally. There are reputed jewelry manufacturers in Jaipur who quote purity in their silver, but very few who conduct the level of authenticity testing that we do.

Step 2: Digitally Controlled Melting

In our purpose-built facility, silver is melted under digitally controlled melting conditions, ensuring both consistency and preventing contamination. Our machines calibrate to ensure silver purity in real time; this is not a common or verifiable practice in silver jewelry exports, even among the commissioned premium silver jewelry exporters in India.

We use modern casting methods to ensure consistent and even distribution while ensuring consistency between batches.

Step 3: Exact Testing of Purity

Once cast, we then perform X-Ray Fluorescence (called XRF) testing on the silver. XRF testing is non-destructive and tests and verifies the metal composition. The technology we use to refine silver is the same technology used by many leading brands of silver jewelry throughout the world.

Each batch receives a certification stamp of 925 sterling silver, validating our purity and testing in an independent laboratory.

Step 4: Skilled Artisans, Trusted Hands

Technology aside, handcrafted jewelry still relies heavily upon the artisanal skill of a craftsman. Like so many others, our artisans have years of experience creating pieces by hand from raw silver under the microscope. Only our artisans can fuse the upmost modern computer-aided design (CAD) technology with old-world hand craftsmanship to meticulously finish your piece—this is what sets us apart from mass-production suppliers.

To add to that, our artisans will not use any lead or nickel, so all pieces are hypoallergenic and safe for your skin.

Step 5: Anti-Tarnish Coating & Finishing

After shaping and polishing, we apply our anti-tarnish solution on each piece of jewelry before it is finished for final inspection. This extra step enhances the life and durability of your jewelry and ensures it will shine and sparkle for years to come. As a reputable sterling silver jewelry supplier, we want to make sure every piece we ship is ready for display, whether in a showroom or your own collection!

Step 6: Final Quality Assessment & Hallmarking

Each piece goes through multiple quality checks! From weight checks to polish evenness to clasp strength—we check everything! After each item is complete, we stamp each piece with the 925 hallmark, which certifies the jewelry is genuine sterling silver globally.
