Coco de Mer: the world's most expensive seed from Seychelles

The Coco de Mer seed, also known as the "sea coconut," is the world's most expensive seed, fetching prices between $600 and $1,000. This exceptionally large seed, weighing up to 20 kilograms, grows exclusively on the Lodoicea maldivica palm trees found on two small islands in Seychelles. The slow-growing palm takes decades to produce fruit, and the seeds themselves take 45 years to mature, contributing to their rarity and high value.
