The 19th century was the golden age of British jewelry craftsmanship. Amethyst necklaces from the Victorian era (1837-1901) were highly sought after by collectors for their exquisite craftsmanship and unique designs. The value of these antique jewels lies not only in the quality of the gemstones themselves, but also closely related to the artisan marks and era characteristics behind them. This article will systematically analyze how to identify amethyst necklaces made by British artisans in the 19th century through marking, covering historical background, marking types, tool usage and case analysis.
The Historical Background of British Jewelry Markings in the 19th Century
The evolution of the jewelry marking system in the UK
Since the 13th century, the United Kingdom has established a strict Hallmarking system for the purity of precious metals.
By the 19th century, this system had been highly perfected and covered the following core elements:
Purity Mark (Standard Mark) : Indicates the metal composition (for example, the silver mark is a “lion” pattern, and the gold mark is a “crown + number”).
Town Mark: Shows the detection location (such as the “leopard head” in London and the “anchor” in Birmingham).
Date Letter: Mark the year in a loop according to the alphabet (changed once a year).
Maker’s Mark: An exclusive abbreviation for a craftsman or workshop (usually 2 to 4 letters).
Technological characteristics of the Victorian era
Material preference: Amethyst is often set in Silver, Gold or Gold Over Silver bases.
Design style: Influenced by the Gothic Revival and naturalism, it commonly features grapevines, flowers, and geometric patterns.
Technological innovation: The popularization of mechanical stamping technology has made the marks more regular, but still retains the traces of manual work.
Key Steps for Identifying the marks of 19th-century British artisans
Step 1: Locate the marked position
The marks of amethyst necklaces in the 19th century were usually located in the following parts:
The inner side of the Clasp of the necklace: The most common position, which is convenient for inspection and does not affect the appearance.
Back or edge of the pendant: If the necklace contains a pendant, the mark may be hidden there.
Metal link connection points: Some artisans will mark the hidden links.
Practical skills: Use a 10x magnifying glass or a jewelry microscope to carefully inspect metal parts under strong light.
Step 2: Interpret the four core markers
Purity Mark (Standard Mark)
Silver products
925 Sterling Silver: Lion pattern (a walking lion with its head to the left).
After 1830, silverware might have been marked with “Britannian silver” (958 purity) (seated female figures).
Gold products
9K gold: Crown + the number “9” or “375” (indicating a gold content of 37.5%).
15K gold (used from 1854 to 1932) : Crown + the number “15” or “625”.
18K gold: Crown + the number “18” or “750”.
Note: During the Victorian era, the export of unmarked precious metal products was prohibited in Britain, so genuine products must have purity marks.
Town Mark
London: Leopard head (no crown, only outline).
Birmingham: Anchor-shaped.
Sheffield: Crown (before 1884) or Rose (after 1884).
Edinburgh: Castle.
Case: If the necklace is marked as “anchor + lion + date letter”, it can be inferred that the place of inspection is Birmingham and the material is 925 silver.
Date Letter
Each detection station uses a unique font and border shape (such as circular or shield-shaped) to mark the year in an alphabetical loop.
Year comparison table: It is necessary to refer to authoritative materials (such as the “Encyclopedia of British Gold and Silver Marking”), for example:
London 1875: The letter “b” (Gothic, shield-shaped border).
Birmingham 1890: The letter “t” (sans-serif typeface, oval border).
Tool recommendation: Use online databases (such as Antique Jewelry University or the official website of the UK Testing Authority) to compare the letters with the years.
Maker’s Mark
It is usually 2 to 4 letters, representing the abbreviation of the name of a craftsman or workshop.
Examples of well-known workshops:
C & S: Carlo & Saraceni (London, specializing in Victorian mourning jewelry).
HB: Harry Burrows (Birmingham, skilled in naturalistic silver amethyst inlays).
Identification method:
Consult the “Directory of British Goldsmiths” (such as Jackson’s Hallmarks).
Compare the auction house archives (such as Christie’s and Sotheby’s auction item databases).
Step 3: Assist in the identification by combining design and process features
In addition to the marking, the process details can further verify the age and origin:
Metal treatment marks
Hand engraving: In the 19th century, artisans often used chisels to carve textures on metals, with fine burrs on the edges.
Mechanical stamping: After 1870, industrial stamping marks became more regular, but they might lack the agility of manual work.
Amethyst cutting method
Old Mine Cut: Common in the 19th century, it had a small countertop, a deep pavilion and an irregular waistline.
Rose Cut: The back is flat and the front is arched. It is mostly used for small-grained amethysts.
Inlaying technique
Bezel Setting: Metal edges encasing gemstones, commonly seen in the early Victorian style.
Pave Setting: It gradually became popular after 1880 due to technological progress.
Guidelines for Identifying Common Counterfeit Marks and Avoiding Pitfalls
Typical loopholes of modern counterfeits
The marking is too clear: The edge of the laser engraving marking is sharp and lacks the slight indentation of the manual marking.
The contradiction between era and style: For example, the necklace marked with the “Birmingham Anchor Mark” adopts the Art Deco geometric design (the style emerged after 1920).
Material mismatch: Necklaces claimed to be from the “Victorian era” use modern alloys or electroplating techniques.
Advanced identification of high-quality counterfeits
Chemical testing: XRF spectrometers can analyze the composition of metals and verify compliance with 19th-century standards.
Ultraviolet reaction: Natural amethyst shows weak reddish-brown fluorescence under long-wave ultraviolet light, while synthetic products may have no reaction or abnormal color.

Conclusion
Identifying the marks of 19th-century British amethyst necklaces is a precise task that combines historical knowledge, technical analysis and accumulated experience. By systematically learning the marking system, mastering the use of tools and drawing on professional resources, collectors can not only verify the authenticity but also deeply understand the craftsmanship inheritance and cultural stories behind each antique. For high-value collections, it is recommended that the final appraisal report be issued by an authoritative laboratory (such as SSEF or GIA) to ensure the safety of the investment.
