Natural diamond scarcity works in two stages: deposits occur in a small number of geological environments on Earth, and gem-quality crystals are only a fraction of what those deposits produce. The rarity of a fine mined diamond is geological and quality-based simultaneously.
Quality & Value
Intrinsic metal value that tracks gold prices, repairability, resizability, and repurposability across decades are the practical reasons a solid gold cable chain holds up as an investment in a way that hollow or plated construction simply can't match.
Origin Story
Brazil dominates quartz gemstone sourcing across varieties. Amethyst, citrine, and rock crystal come primarily from Brazilian deposits, with Uruguay and Madagascar contributing fine material in specific ranges. Understanding that source concentration helps explain why gem-quality quartz is consistently available across varieties in a way most mineral families can't replicate.
