The boxes were lined in ivory colored silk and had La Tausca Pearls printed in gold lettering on the inside of the lid. Sometimes you might find the boxes marked "Patented April 8th 1924." Some other jewels were made up of opaque glass and simulated coral, onyx, jade or turquoise. The colors of the glass jewels are emerald green, citrine yellow, sapphire blue, topaz orange, peridot green, garnet red, amber and/or amethyst purple. Sometimes you can find the boxes without the jeweled ornamentation. I have also had the rare opportunity to see a few boxes with both a shell cameo, glass intaglio, faux pearls and/or jewels on the lids.
The high quality faux pearls were sold in filigree and jeweled gilt bronze, silver or copper finished brass presentation boxes (jewel caskets) in the 1915-1930s. A gilt metal medallion was attached to all of the jewelry and can sometimes be found intact. In many instances these clasps also had a little genuine diamond chip. These faux pearls were advertised as indestructible and often had 14kt gold filigree clasps that were marked La Tausca.
