916 / 22K Gold — What This Hallmark Means

A "916" mark signifies 22-karat gold, composed of 91.6% pure gold and only 8.4% alloying metals (usually copper and silver). In the karat system, 22 out of 24 parts are pure gold, making this one of the highest-purity gold alloys used in jewelry. The 916 designation comes from the metric fineness system — 916 parts gold per 1000 parts total.

22K gold has an exceptionally rich, deep yellow color that is immediately distinguishable from lower-karat golds. This intense golden hue is highly prized in Indian, Middle Eastern, and Southeast Asian cultures, where 22K gold is the traditional and preferred standard for wedding jewelry, ceremonial ornaments, and investment pieces. In countries like India, the gold jewelry market is dominated by 22K pieces.

Due to its high gold content, 22K gold is significantly softer than 14K or 18K gold. This means it scratches and dents more easily and is generally not recommended for jewelry with intricate settings or for pieces that will endure heavy daily wear. However, its softness also allows for the detailed hand-crafting techniques that characterize traditional South Asian and Middle Eastern goldsmithing.

The 916 stamp is typically found inside ring bands, on clasps, or on small tags attached to necklaces, bangles, and chains. In Indian jewelry, the mark is often accompanied by a BIS (Bureau of Indian Standards) hallmark, which includes the BIS logo, purity grade, assay center mark, and jeweler's identification mark.

Middle Eastern 22K gold may carry different regional hallmarks. Turkish 22K gold features the tugra mark, while Gulf state jewelry often shows the 916 stamp alongside a maker's mark. In Southeast Asia, particularly in Thailand and Malaysia, 22K gold items are stamped with 916 or local equivalent markings.

Variations include "916," "22K," "22KT," "22CT," ".916," and "917" (a rounding variation). Indian jewelry following the BIS hallmarking scheme will show a specific set of marks including purity, assay office symbol, and year code. Some older Indian pieces use the designation "KDM" (kadmium/cadmium), referring to the soldering method rather than purity, though cadmium soldering has been largely discontinued for health reasons.

In some markets, you may see "916 HM" where "HM" stands for hallmarked, confirming the piece has been assayed and certified by an authorized testing center.

A common misconception is that 22K gold is too soft to be made into jewelry. While it is indeed softer than lower-karat golds, 22K gold has been used for thousands of years in elaborate jewelry across many cultures. Traditional techniques accommodate the metal's softness, and many 22K pieces are designed with thicker profiles to compensate.

Another myth is that 22K gold never needs the alloy metals and could just be made from pure 24K gold. The small percentage of alloying metals in 22K gold is crucial — they provide enough structural integrity to allow the gold to be worked into jewelry shapes and to hold those shapes during wear.

If you have a 916-marked piece, handle it gently as it can scratch and deform more easily than lower-karat gold. Store 22K gold pieces individually in soft cloth pouches to prevent scratching. Avoid wearing 22K gold rings during manual work or exercise.

For verification, especially important given the high value of 22K gold, have the piece tested by a certified jeweler or assay office. In India, you can verify BIS hallmarks through the Bureau of Indian Standards website. 22K gold retains its value well and is often considered both jewelry and a financial investment.
