In the selection of gold jewellery or investment bars, “foot money” and “foot money” are the two most commonly encountered by consumers, which appear to be similar, with subtle but critical differences in their meaning. In short, “foot money” is a generic term for gold purity that meets national standards, while “foot money” is a more specific subcategory with a higher median purity. Since 2025, understanding the precise differences between jewellery processes and consumer awareness has become a first step towards avoiding misconsumption and making informed choices. This paper will provide you with a thorough analysis to help you become a good consumer of gold。
I. Transport: definitions and evolutions under national standards
To clarify concepts, it is important to start with national standards. China's naming norms on gold purity have evolved and are essential for understanding the current market。
1. 1 the end of the “thousands of gold” era and the integration of “full gold”
Prior to 2016, there were references to “glubber” (nine hundred and ninety-nine thousand gold) and “glubber” (nine hundred and ninety-nine and nine thousand gold) in the market, which were used as symbols of high purity. However, overly disaggregated purity markings have led to market disorder and process constraints. As a result, the national standard gb 11887-2012 " provisions on the purity of precious metals and the method of naming them " was amended in 2016 to remove the terms "grand gold", "grand gold", and to provide for gold jewellery containing not less than 990 per cent of gold, with a uniform label as "foot gold". This revision is intended to regulate the market and lead industries to focus more on the design, process and not simply on purity figures。
1. 2 status of “999 full gold”: high purity market usage
As a result of the revision of the national label, “999 gold” is no longer an official mandatory name, but it is still widely used as a high purity representative within industry and in the hearts of consumers. The “999 gold”, “au999” or “g999” labeled on the market today refer to all gold products containing gold of 999 per thousand or more. It falls within the category of “foot money”, but usually represents the higher-intensity part of the gold. Thus, the logical relationship now is that 999 plentiful gold must have been plentiful, but not necessarily 999 platitudes (only 990 pesetas)。
Core differences multi-dimensional: purity, process and value
When we understand the definition, we compare it with a few core dimensions。
2. 1 pureness and colour: fine numbers, essential differences
That is the fundamental difference. The gold content threshold for “full gold” is 990 per thousand, meaning that its gold content is not less than 99. 0 per cent. The amount of gold contained in “999 gold” is not less than 999 tons, or 99. 9 per cent of gold. The difference in purity is between 0. 9 and 9. 9 per thousand. For a 10-gram ornament, the content of gold may vary from 0. 009 to 0. 099 grams. Although colour differences are difficult to detect in the naked eye, they are directly valued under sophisticated instruments and when recovered as feedstock。
2. 2 processes and plastics: pureness as an invisible constraint on design
The higher the purity, the softer the gold. Thus, due to its higher purity and relatively softness, gold is more difficult to process and needs to be worn with greater care to avoid deformation when making complex, sophisticated jewellery (e. G., fine necklaces, mosaic jewellery) with fine card buttons or with greater support. Some of the jewellery, labelled “foot gold”, may be contained in the order of 995 per 1,000, with a slight increase in hardness while maintaining high purity, which is more conducive to modern design and long-term requirements for diversification. Today, in 2025, many fashionable 3d hard, 5g gold products, although partially pure in gold to the full or even 999 standards, have changed the crystal structure through advanced processes, striking a balance between hard and pure。
2. 3 value and price: how do we calculate not to lose
In terms of raw material value, 999 full gold is usually higher than ordinary gold (e. G. 990) due to its higher purity. International gold prices usually correspond to 99. 99 per cent pure gold, so that the price of 999 full gold is closer to the price of raw materials. At the retail end, there are minor differences in pricing per gram, and there may be a slight increase in the cost of fully paid work. However, at the time of recycling or recycle, the collector would normally test the actual purity and settle strictly on the percentage of gold, where the advantage of 999 gold would be felt. The price of ordinary gold jewellery is more integrated into the value added of brands, designs, processes, etc。
Iii. Practical guidelines for greenhouse purpose in 2025 and corrections
Faced with the market, we need to update our knowledge and avoid common traps。
3. 1 how precisely are they identified? It's important to read the mark
Precious metal jewellery must be stamped in accordance with the national label. Please accept that “full money”, “au 990”, “g990” and so on, and “full money 999”, “au 999”, “g999,” and so on. At the same time, clear content should be viewed on brand labels or certificates. Be careful not to believe in verbal propaganda and everything is subject to physical marking and authoritative testing certificates。
3. 2 perceptions corrected: purity is not the only criterion for selection
A common area of error is the blind pursuit of “999” over the others. Correct the following:
3. 3 choice by necessity: your needs determine your choice
Iv. Common answers (faq)
Q: is it time to buy gold
Response: not necessarily. It depends on your primary needs. If the value of the investment is preserved and the value of the raw materials stored, it is better to have 999 gold and above purity. In the case of aesthetics and novelty, priority should be given to design, process and wear effects without having to adhere to 999 while ensuring that they are “full”。
Q: what difference does it make between the gold and the 999 gold
A: under normal circumstances, there is little difference between the two colours, and they all appear to be richly bright yellow. The surface may be slightly dim as a result of frictions or because of exposures, but this has little to do with purity and can be restored to light by regular professional cleaning。
Q: is it credible that the merchant said, “this is gold, that is, three nines”
Answer: untrustworthy. According to the national label, “foot money” represents only 990 ghz per thousand purity, not specifically 999. The specific mark on the inside of the jewellery must be viewed, if it is “foot money 999” or “au999”, the three nines; if it is only “foot money”, it may be 990, 995 or more。
Q: what is the difference between the price of the gold and the price of 999 at the time of recovery
Response: the recovery price is calculated on the basis of the international gold price and actual purity of the day. Assuming that the daily value of the gold is 500 usd per gram, the recovery price of the gold is about 495 usd/g for 990 per ounce of purity, while the recovery price of the purity is about 499. 5 yuan/g. The specific price differentials fluctuate with the price of the gold, but the calculation rationale remains unchanged。
Q: what is k-gold/falk 999
A: this is a completely different system. K gold is alloyed with gold and other metals, such as 18k gold containing 75 per cent of gold. K gold is rich (white, red, colour, etc.) with a high hardness and suitable for complex embedding. Full and 999 gold, on the other hand, emphasize high gold content, which falls into different product categories and meets different consumption needs。
In sum, in 2025, in the gold-consumption market, “full gold” is the baseline against which you can buy real gold, while “fully 999” is the basis for a quest for greater purity. Wise consumers should move away from digital myths and make comprehensive judgements about their different demands for clothing, collections and investments, so that every penny is worth money。
