The value of a Fabergé egg, particularly a unicorn-themed one, can vary significantly based on its provenance, condition, and the market demand. Authentic Fabergé eggs are known to fetch millions at auctions, with some selling for upwards of $20 million. However, as of my last knowledge update in October 2023, no specific "unicorn Fabergé egg" is widely recognized, so its worth would depend on the individual egg's characteristics and historical significance.
