Prestige Stones

Prestige Stones is based in Kenya and currently lists 13 active products across mineral, nut and specialty commodity categories. The catalogue includes mica, quartz crystals, graphite‑flakes, lead ore, manganese ore, fluorite, tantalum/coltan and related concentrates, each identified with its respective HS‑code family such as 2525.10 for mica and 2506.10 for quartz. In addition to mineral products, the supplier offers agricultural commodities including African art items, macadamia nuts, cashew nuts, coffee beans and gum Arabic. All listed items are sourced within Kenya’s mining regions and agricultural zones, providing a geographically concentrated supply base.

The mica entry refers to natural muscovite or phlogopite with the chemical formula KAl2(AlSi3O10)(OH)2 and falls under HS chapter 25 for mineral products. Quartz crystals are described as natural SiO2 specimens classified under HS 2506.10, typically supplied in sizes ranging from 5 mm to 30 mm. Graphite‑flakes are natural carbon with 80‑95 % purity and are listed under HS 2504.10, while lead ore (galena) contains 50‑70 % lead and uses HS 2607.00. Manganese ore (30‑48 % Mn) and fluorite (CaF2) are recorded under HS 2602.00 and 2529.21 respectively, and the tantalum/coltan concentrate (Ta2O5) appears under HS 2615.90. The nut and agricultural products are not assigned HS codes in the supplied data, but they typically fall under HS 0801‑0805 for nuts and HS 0901 for coffee.

The mineral portfolio comprises natural mica (often graded 99 % purity with flake sizes 10‑100 µm), quartz crystals (commonly 99.5 % SiO2 with clear or milky inclusions), flake graphite (80‑95 % carbon, bulk density 1.2‑1.5 t/m³), lead ore (galena concentrate 50‑70 % Pb, moisture <5 %), manganese ore (30‑48 % Mn, silica 10‑15 %), fluorite (CaF2 purity 95‑99 %, calcium carbonate equivalent 90‑95 %) and tantalum ore (Ta2O5 concentrate typically >30 %). These commodities are usually shipped in bulk bags (1 t) or wooden crates for mineral concentrates, and are subject to standard HS‑code customs documentation.

The agricultural side includes macadamia nuts (kernel grade AA, moisture ≤2 %), cashew nuts (grade W180, shell‑to‑kernel ratio ~2.5:1), coffee beans (Arabica, 12‑14 % moisture, screened 16‑18 mm), and gum Arabic (soluble solids 80‑85 %). Such products are commonly packed in jute or polypropylene bags of 20‑25 kg, sealed for moisture protection, and may carry phytosanitary certificates under the International Plant Protection Convention.
