Studs are measured across the face, hoops by their inner diameter, and drops from the top of the post to the lowest point of the piece. Where a measurement is published for a style it appears in the specification above. For a sense of scale: a six or seven millimeter stud is the everyday size most people reach for, and a hoop past forty millimeters is a decision you have made for the evening. More in our Size & Fit Guide.

Yes. Every piece is made in genuine metal — 10K, 14K, or 18K gold, or 925 sterling silver. All pieces are stamped with the corresponding metal marking.

Rhodium is a member of the platinum family, applied as a very thin outer layer. It makes the metal beneath brighter and whiter and slows tarnishing considerably. It is a plating rather than a permanent change, so it wears with time and can be reapplied by most jewelers.

In time, yes. Silver reacts with sulfur present in ordinary air, and the darkening that follows is chemistry rather than a fault or a defect. A soft dry cloth lifts it. Storing the piece in a closed pouch away from humidity slows it down, and rhodium plating, where a piece carries it, slows it further still.

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.
