nvisibly set jewelry originated in the 1920s from the jeweler’s desire to show only gemstones, hiding the precious metal mountings.
1929 a relatively unknown Parisian jeweler named Jacques-Albert Algier was the originator of the invisible setting.
He developed and patented a method of holding a gem in place without bending metal over its crown—no prongs or bezel.
He did this by carving a groove in the side of the gem’s pavilion and sliding the gem along rails of precious metal, setting gemstone next to gemstone and effectively masking the metal.
The invisible setting is very beautiful but also the most difficult of all the setting techniques. It requires to groove and cut each stone individually. It is also the least secure setting because there is no metal around the stones.
This setting was used only with color stones, not with diamonds, (The diamonds in the VC &A pieces seen in the pictures were set with prongs.) because diamonds are much harder than color stones and it was impossible for the jewelers to make grooves in the diamonds.
