With a common MOQ of 5 kilograms, buyers should plan for large-volume orders to unlock competitive pricing, while the global supplier base across India, China, Singapore, the U.S., and Vietnam offers geographic diversity to mitigate supply disruptions. The vast price range—from $16 to $36,000 per kilogram—means product quality, material type, and craftsmanship vary dramatically, so buyers must prioritize detailed product specifications and verification to avoid overpaying for lower-tier items.
