This article explores the often-opaque journey of a diamond from its geological origins to a finished gem, detailing the key stages of exploration, processing, and distribution that underpin its value.

Information about the mysterious diamond industry is often not widely known, including how diamonds become a source of immense value. To transform the sediment where diamonds are found mixed with dirt and rock fragments, diamonds must undergo a series of processes.
The diamond supply chain includes exploration, mining, sorting, cutting, polishing, jewelry manufacturing, management, and the sale of the final product.
Diamonds are extracted from the earth through five main types of mining: artisanal mining, hard rock mining, marine mining, open-pit mining, and alluvial (placer) mining.
Like all processes in the diamond supply chain, sorting is a crucial step in creating valuable retail diamond jewelry. Good selection of diamond rough at this stage translates into high-quality diamond jewelry further down the supply chain.
The extreme hardness of diamonds means they can only be cut by other diamonds. Therefore, diamond cutting requires highly specialized artisans, tools, equipment, and techniques. Cutting transforms a rough diamond into a polished gemstone ready for jewelry. Any error at this point in the supply chain can severely impact profits and supply. A perfect cut adds significant value to a diamond. Because large diamonds are much rarer than small ones, prices increase substantially with size.
After the raw material processing stage, which is a specialized phase of the supply chain, diamonds are distributed to wholesalers, then to retailers, and finally to consumers.
Three major headaches for domestic jewelers today are: ① Sourcing (supply chain management), ② Inventory management, and ③ Branding (brand marketing). Many jewelers express that inventory backlog and declining performance, while seemingly due to increased competition and poor sales, are essentially caused by inefficient supply chains! How can investors’ costs be reduced? This must be solved at the source of “sourcing” by finding the right product channels!
The traditional jewelry sales supply chain is overly lengthy, involving rough stone procurement, transportation, processing, manufacturing, and distribution through various levels of dealers before reaching the retailer. Now, Zuan Ying’s procurement process includes inventory from suppliers and direct supply from global top-tier loose diamond suppliers, reducing intermediate procurement links and effectively controlling supply sources and costs.
Why jewelers choose Carat Feast:
1. On September 5, 2018, Zuan Ying signed a strategic cooperation agreement with China Huirong and Haoyi Diamonds. SRK is India’s largest diamond supplier. Its Chinese diamond brand “Haoyi Diamonds” is a member of the Shanghai Diamond Exchange. Direct supply from the diamond source reduces intermediate procurement links, achieving resource sharing with jewelers.
2. Carat Feast’s diamonds are priced 30%-50% lower than market prices.
The strength of the diamond supply chain is most directly felt by jewelers in three main aspects: quality assurance, reasonable pricing, sufficient supply with fast delivery, and avoidance of inventory backlog.
Innovative Service Advantages of Carat Feast: 100% direct sourcing and stocking, 100% product return and exchange. A new marketing model with zero-cost adoption, direct supply from source, global lowest price with single-piece ordering. International authoritative GIA certification for quality assurance, full support from the listed company China Huirong, and unconditional cooperation with billions in inventory for promotional activities.
Zuan Ying, with years of experience in the diamond industry, possesses rich expertise in diamond production and processing and has accumulated extensive resources from diamond suppliers and processing factories. It integrates upstream international DTC diamond suppliers to serve downstream terminal jewelry stores, solving problems for jewelers such as shortage of carat-level supply, high prices, too many intermediary links, and lack of customization capabilities.
