Henry Sam signed his jewelry with a capital H S, spaced apart with a printed sterling stamp above his initials, just like on this organic shaped large shadow box ring. The high grade natural turquoise, as seen in the photos, is exquisite! Wonderful hues in person. The size of this ring is 8.5, and it weighs 13 grams. The ring measures approximately 1.10/16″x 1.2/16″. Please feel free to ask questions.
