The Confidence to Collect
There is a unique thrill in finding the perfect piece of antique jewellery. Whether it’s an Edwardian platinum ring or a heavy 15ct gold Victorian Albert chain, these pieces carry history, craftsmanship, and a story that modern jewellery simply cannot match.
But buying antique jewellery - especially online - requires a high level of trust. How do you know the piece is truly from the era claimed? At Hudsons Estate Jewellery, we believe that preserving history means providing absolute transparency. We don't rely on guesswork; every piece in our collection goes through a rigorous, multi-stage authentication process. And yes, sometimes this means it doesn't make it onto our website!
Step 1: The Art of the Hallmark
For centuries, assay offices have stamped precious metals to certify their purity, origin, and maker. Reading these hallmarks is the first step in unlocking a piece’s provenance. When evaluating a new arrival, we inspect the stamps under high magnification to identify:
The Purity: (e.g., 9ct, 15ct, 18ct, or sterling silver).
The Assay Office: Identifying exactly where the piece was tested, such as the famous Chester or Birmingham offices.
The Date Letter: Allowing us to pinpoint the exact year of manufacture.
However, just because an item may not have a hallmark, doesn't mean it's not a genuine antique. Many pieces from different eras and regions may not have them, especially if they were made before the hallmarking system was established and mandatory.
Step 2: The Assurance of Acid Testing
To complement our historical research, we believe in confirmation through multiple methods. We conduct acid testing as a supporting check.
Performed carefully and on discreet areas, acid testing involves:
- Applying a small sample of metal to a testing stone
- Using acid solutions calibrated for gold, silver, or platinum
- Observing the reaction to confirm metal purity
Though traditional, this method remains an invaluable tool for cross-referencing results - adding an extra layer of confidence.
Step 3: The Science of XRF Testing
This is a high-tech, non-destructive method used to determine the elemental composition of the metal. For select pieces, particularly when visual or structural cues raise questions about plating, restoration, or unusual alloying we utilise XRF testing.
Why XRF:
Zero Damage: XRF preserves the integrity and patina of the antique piece.
Pinpoint Accuracy: It provides a precise breakdown of the alloy, measuring the exact percentages of gold, silver, and copper down to the decimal point.
Step 4: The Essential Human Element
Science and technology can tell us a great deal, but experience completes the picture.
Because XRF only examines the surface, a trained human eye is essential to detect heavy Victorian gold-plating or rolled gold over a base-metal core. We consult GAA (Gemmological Association of Australia) registered NCJV (National Council of Jewellery Valuers) experts for further assessment.
This is where the difference between a machine and a curator matters. We never rely on one test alone. To ensure a piece is solid gold and not a brilliant antique imitation the process includes (but is certainly not limited to):
The Loupe Test: Inspection of high-wear points. Over a century of wear, plating eventually thins, while solid gold remains true throughout.
Density and Weight: Comparing weight to dimensions - solid gold has a specific density that a brass-core piece cannot replicate.
Era-Specific Construction: Understanding how a jeweller in 1906 constructed a ring tells us where a piece might be hollow or reinforced.
Wear Your History with Absolute Certainty
When you purchase an heirloom, you are making an investment. By combining deep historical knowledge with modern XRF technology and a rigorous physical audit, we remove the guesswork from collecting.
When you read a description on our site that states a brooch is "15ct gold" or a ring is "Chester 1906," you can add it to your collection with absolute confidence, knowing both the science and the history stand behind it.
