Founded in New York in 1837, Tiffany & Co. changed the way the world wears the solitaire. In 1886, the house introduced the Tiffany Setting: a six-prong mount that raises the stone above the band so that light passes through it from below. It remains the benchmark for the engagement solitaire today.

House engravings and hallmarks, designer's signature on the Peretti and Schlumberger lines, fineness of the silver or gold, soundness of the prongs on solitaires, presence and consistency of the laboratory report when one accompanies the stone.
Yes, they bear the designer's signature in addition to the house hallmark. It is a systematic check.
The pieces are sold in their original condition. Re-engraving is possible with an engraver, but it alters the piece and may affect its value.
