Geological Origin: Originates from fossilized resin of the extinct legume tree Hymenaea protera, dating back millions of years to the Miocene epoch. Physical Properties: Weight & Feel: Warm and organic to the touch, noticeably lighter than cold mineral stones. Aroma: Emits a sweet, pleasant pine-resin fragrance when gently rubbed, polished, or heated. Inclusions: Frequently contains authentic organic plant matter, micro-sediments, or natural resin flow lines that demonstrate genuine fossil formation. Uses & Market Value Lapidary & Jewelry: Regularly cut, shaped, and polished into statement pendants, cabochon rings, bead bracelets, and luxury prayer beads.
