Yes. Every Sana Jewels piece is covered by a 3-month warranty against manufacturing defects from the date of delivery, and a missing stone is replaced free for the same 3 months (excluding any single stone of 0.12 carat or larger). The warranty is valid in the USA only, and any repair performed by another jeweler will void it. Full terms are in our Return & Refund Policy.
