Hi Marcus,
Thank you for sharing your feedback about the Coherence bracelet. We're sorry to hear that a glass stone fell out of its setting after just three days of wear, especially since you were careful to avoid any impacts or damage to the piece.
We understand how disappointing this must be when you were hoping to incorporate the bracelet into your daily wear routine. A stone becoming loose and falling out within such a short timeframe is certainly not the durability standard we aim for, and we apologize that this happened with your purchase.
Your observation about the prong construction and its impact on stone security is extremely valuable feedback, and we take this concern very seriously. Product durability, particularly for pieces intended for regular wear, is very important to us.
Please contact our support team at info@vitalydesign.com, and one of our support agents will be happy to assist you with filing a warranty claim.
