A couple claims the Beleza Emerald was lost in the Camp Fire of 2018 and was worth $280 million. The valuation doesn't add up to us, and we explain why.
2 Minute Read
Apparently, there's an impending legal battle with Pacific Gas and Electric — who was found liable for the faulty wires that started the fire — over whether or not the specimen was actually in the Bieglers' possession, if it was actually destroyed, and how much it was worth. The Bieglers claim the stone was mined in Brazil and that it's worth an attention-grabbing $280 million USD.
IGS will be very interested to hear more about how this valuation was determined. It raises red flags and alarm bells for a few reasons.
Taking a comparable sales approach to valuation, the numbers just don't add up. Take, for example, the 341-kg (approximately 752 pounds) "Bahia Emerald," discovered in Bahia, Brazil in 2001. Forbes says this specimen "could be worth $309 million." Based on photos published online, the Bahia Emerald seems to be only about 10% emerald. The rest consists of mica and quartz matrix.
If you extracted 34 kg of actual rough emerald from the Bahia, it would yield approximately 34,000 carats of cut stones. Closeup photos indicate it's predominantly low to medium-quality material, maybe suitable for bead making and cabbing — but not faceting. Therefore, assigning a generous $100 per-carat average value brings the total to a little over $3 million. That's about 1% of the highly speculative $309 million figure in Forbes.
Apply the same formula to this 500-pound "solid block of black schist and quartz with green crystals" and you'd be lucky to reach $2.3 million. Like I said, Brazilian gem traders are market savvy. If they thought they could have extracted $2.3 million worth of cut emeralds from this massive specimen, it never would have left Brazil intact.
Of course, anything is possible in life. We haven't seen the specimen or even a picture of it. However, based on the little information we do have, something seems off here. If anyone has more information on the Beleza Emerald, we'd love to include it and expand this article's scope.
