This is a Mexotica Mexican opal matrix and tourmaline cast sterling silver pendant featuring a unique pear-shaped earthy stone set in handcrafted textured silver.
The retail value of an original, artisan-crafted Mexotica Mexican opal matrix and tourmaline cast sterling silver pendant typically ranges between $250 and $450 USD, depending on the size, fire intensity, and specific layout of the stones
Because Mexotica jewelry pieces are individually handmade, one-of-a-kind creations utilizing the "lost wax" casting process, their value is tied directly to their artisan collectibility and the individual quality of the gemstones.
Key Value Drivers
The exact pricing within this range depends on several unique characteristics:
Opal Matrix Quality: Mexican matrix opal (often called Cantera opal) features a play-of-color fire suspended within its natural host rock (rhyolite). Luminous flashes of electric green, orange, or blue drastically elevate the piece's value.
Tourmaline Accent: The color saturation and clarity of the added tourmaline accent piece influence the final appraisal.
Total Weight & Scale: Larger structural pendants (e.g., pieces weighing 15 to 25 grams and stretching 4 to 5 cm in length) sit at the upper end of the valuation scale.
Artisan Authenticity: The pendant should feature standard .925 silver hallmarks alongside the signature maker markings or initials tied to the Mexotica brand
