This dataset contains Official Train and Metro Utilisation figures. Opal tap-on/tap-off data (representing an individual entering & exiting a station), is allocated to a line and aggregated to a monthly figure for the estimated number of trips. Starting July 1, 2024, the methodology for calculating trip numbers for individual lines and operators will change to more accurately reflect the services our passengers use within the transport network. This new approach will apply to trains, metros, light rail, and ferries, and will soon be extended to buses. Aggregations between line, agency, and mode levels will no longer be valid, as a passenger may use multiple lines on a single trip. Trip numbers at the line, operator, or mode level should be used as reported, without further combinations. The dataset includes reports based on both the new and old methodologies, with a transition to the new method taking place over the coming months. As a result of this change, caution should be exercised when analysing longer trends that utilise both datasets.

About this dataset

Context

The dataset tabulates the Opal population over the last 20 plus years. It lists the population for each year, along with the year on year change in population, as well as the change in percentage terms for each year. The dataset can be utilized to understand the population change of Opal across the last two decades. For example, using this dataset, we can identify if the population is declining or increasing. If there is a change, when the population peaked, or if it is still growing and has not reached its peak. We can also compare the trend with the overall trend of United States population over the same period of time.

Key observations

In 2023, the population of Opal was 65, a 1.56% increase year-by-year from 2022. Previously, in 2022, Opal population was 64, a decline of 1.54% compared to a population of 65 in 2021. Over the last 20 plus years, between 2000 and 2023, population of Opal decreased by 37. In this period, the peak population was 109 in the year 2019. The numbers suggest that the population has already reached its peak and is showing a trend of decline. Source: U.S. Census Bureau Population Estimates Program (PEP).

According to Cognitive Market Research, The Global Opal Jewelry market size is USD XX billion in 2023 and will grow at a compound annual growth rate (CAGR) of 5.80% from 2023 to 2030.

Consumer awareness of the genuineness of the metals and gems used in jewelry is expanding, which is driving the sector.
Demand for rings remains higher in the opal jewelry market.
The women's sector held the highest opal jewelry market revenue share in 2023.
Europe will continue to lead, whereas the North American opal jewelry market will experience the fastest growth until 2030.

Increasing Disposable Income & Spending Power of Consumers to Provide Viable Market Output

Due to the population's high disposable income and purchasing power, the global economy is expanding, which is driving demand for more luxury products like opal jewelry.

In OECD nations, when adjusted for purchasing power parity, the United States had the highest gross household disposable income per capita in 2021. Their per capita disposable income was close to USD 55,000. With about 50,000 dollars, Luxembourg came in second, and Switzerland came in third.

Additionally, a variety of worldwide traditions relating to the adoption of opal jewelry are anticipated to increase product demand greatly. For instance, in August 2020, an article published by the World Gold Council stated that on significant events, Chinese people customarily give gold presents to the younger family members. In addition, the market will keep growing as more women enter the workforce and as consumer awareness of luxury and contemporary stones rises. The increase in female labour force participation has been one of the most prominent economic developments.

Growing Return On Investment (ROI) to Propel Market Growth

The high return on investment (ROI) of jewelry products is expected to drive the growth of the global opal jewelry market. The return on investment for jewelry has only grown or stayed the same for many years. There have only been a few instances where the cost of the raw materials used to make actual jewelry has fallen. Since there is practically a 100% guarantee that the investment value will not decrease even after years of purchase, jewelry continues to be a popular way for many families or individuals to invest money.

India's gold prices in 2023 have changed over time. The cost of gold has increased considerably since 2022. The price of the yellow metal rose by over Rs. 3,000 during the first six months of the year, an increase of nearly 6.5%.

196 Global export shipment records of Opal with prices, volume & current Buyer's suppliers relationships based on actual Global export trade database.

A complete list of live websites using the opal technology, compiled through global website indexing conducted by WebTechSurvey.

We have determined germanium/silicon ratios in purified diatoms and radiolarians from siliceous sediments in Holocene core tops, one late Pleistocene piston core, and four high-latitude Southern Ocean Deep Sea Drilling Project (DSDP) sites ranging in age from Holocene to Oligocene. High-latitude Holocene diatoms in the 10- to 38-µm size fraction ([Ge/Si]opal = 0.693 +/- 0.039 * 10-6) faithfully record the present oceanic ratio ([Ge/Si]seawater = 0.699 +/- 0.004 * 10-6). This confirms that diatoms from siliceous oozes are monitors of seawater Ge/Si and may record past changes in rates of delivery of weathering products to the sea from continental and seafloor weathering. Large diatoms and radiolarians display ratios much lower than (Ge/Si)seawater, suggesting that (Ge/Si)opal, to some extent, displays the effects of biological fractionation. From 0 to 2.5 m.y.B.P., (Ge/Si)opal in diatoms from DSDP sites ranges from about 0.54 to 0.70 * 10-6, similar to the range observed in one late Pleistocene piston core over the last 25 kyr. From 2.5 to 6 m.y.B.P., the ratio is more variable, while prior to 10 m.y.B.P., ratios are clearly higher, averaging about 0.9 * 10-6 in the early to middle Miocene. Low values of the ratio are consistent with global weathering regimes dominated by river silica input to the sea, while higher ratios suggest periods of enhanced hydrothermal input or reduced fluvial contribution. Nevertheless, an oceanic one-box model with variable river and hydrothermal inputs and biogenic opal output cannot adequately account for the magnitude or the timing of changes observed in the record, suggesting the existence of other sources/sinks for inorganic germanium and/or silicon to or from the sea.

OPAL

Opal Bracelet Market Outlook

The global opal bracelet market size is projected to grow from USD 1.2 billion in 2023 to USD 1.8 billion by 2032, exhibiting a compound annual growth rate (CAGR) of 4.5% during the forecast period. This growth is primarily driven by the increasing consumer preference for unique and customizable jewelry pieces, coupled with the rising disposable incomes and changing fashion trends. The opal bracelet market's growth is also bolstered by the gemstone's cultural significance and its appeal to a wide range of demographic groups.

One of the key growth factors for the opal bracelet market is the rise in disposable income among consumers globally. With higher disposable incomes, consumers are more willing to spend on luxury items, including opal bracelets. Moreover, opals are often perceived as unique and exotic gemstones, which further entices consumers looking for distinctive and personalized jewelry pieces. Additionally, the increasing popularity of fashion-forward jewelry designs has seen opal bracelets becoming a trendy accessory, contributing significantly to market growth.

Technological advancements in jewelry manufacturing have also played a pivotal role in the market's expansion. Innovations in gemstone cutting and setting techniques have made it possible to produce more intricate and visually appealing opal bracelet designs. Moreover, the use of synthetic opals provides an affordable alternative to natural opals, making these bracelets accessible to a broader audience. The integration of advanced e-commerce platforms has also facilitated easier access to these products, broadening the market's reach and enhancing consumer engagement.

Cultural and astrological beliefs associated with opals also drive their market demand. Many cultures and communities believe that opals bring good luck, fortune, and emotional stability. This belief has made opal bracelets popular as gifts for special occasions such as birthdays, anniversaries, and other milestone events. The gemstone's aesthetic appeal, combined with its supposed mystical properties, has helped sustain its popularity, ensuring consistent market demand.

Regionally, the Asia Pacific market is expected to witness significant growth due to the increasing middle-class population and their rising disposable incomes. The burgeoning e-commerce sector in this region also supports market growth by providing consumers with easy access to a variety of opal bracelets. In contrast, North America and Europe are mature markets but continue to demonstrate steady demand driven by fashion trends and cultural preferences. These regions' established retail infrastructure further supports the opal bracelet market's expansion.

Product Type Analysis

In the opal bracelet market, the product type segment is bifurcated into natural opal bracelets and synthetic opal bracelets. Natural opal bracelets are highly prized for their uniqueness and the natural variations in their color and patterns, making each piece distinct. These bracelets cater to consumers who value authenticity and are willing to pay a premium for genuinely sourced gemstones. The allure of natural opals is further enhanced by their rarity, which makes them a status symbol among jewelry connoisseurs.

Synthetic opal bracelets, on the other hand, offer a more affordable alternative to natural opals. These lab-created stones mimic the appearance and characteristics of natural opals but are available at a fraction of the cost. This makes synthetic opal bracelets accessible to a broader demographic, including younger consumers and those with a limited budget. The advancements in synthetic gemstone technology have significantly improved the quality and appearance of these stones, making them an attractive option for cost-conscious buyers.

The market for synthetic opal bracelets is also driven by ethical considerations. As consumers become more aware of the environmental and ethical issues associated with gemstone mining, there is a growing preference for synthetic alternatives that offer a more sustainable option. This trend is particularly strong among younger, environmentally-conscious consumers who seek to make ethical purchasing decisions without compromising on style and quality.

In addition to opals, Chalcedony Bracelets are also making waves in the jewelry industry. Chalcedony, with its soothing blue hues
