Description

18K Gold and Bronze Rare James Tassie Poseidon MedallionAttributed to the James Tassie workshop, circa the late 18th century, this rare medallion was most likely used as the master mold for creating the glass gemstones that James Tassie was known for. The glass mimicked carnelian and other precious stones, which were famously used as intaglios in Georgian jewelry. Because this bronze mold is so special and rare, we added an 18k gold bezel so that the piece could be worn today as a beautiful pendant.

Attributed to the James Tassie workshop, circa the late 18th century, this rare medallion was most likely used as the master mold for creating the glass gemstones that James Tassie was known for. The glass mimicked carnelian and other precious stones, which were famously used as intaglios in Georgian jewelry. Because this bronze mold is so special and rare, we added an 18k gold bezel so that the piece could be worn today as a beautiful pendant. Bronze, a hard metal, allows for intricate definition, and due to its age, the medallion has acquired a gorgeous multi-colored patina that emphasizes the high points, shape, and line work of the bas relief. The added bezel accentuates the thickness of the ingot, as the gold border picks up the depth of the patina, pulling the eye into this seductive medallion. 

The medallion depicts Poseidon, god of the sea, riding two hippocampi across turbulent ocean waves. The oval medallion hangs horizontally from an oversized bail, and the texture of the waves catches the light and gives the pendant extra depth.  Created as part of our signature collection, this is a one of a kind piece of jewelry. 

Born in 1735, James Tassie was a Scottish stonemason who invented a glassy white paste perfect for replicating gemstones. Tassie was commissioned across Europe, first by Catherine the Great of Russia, then by the Wedgwood factory, to create imitation gemstones and elaborately carved intaglios. In 1773, most of the infamous blue and white cameos in the Wedgwood catalogue were cast from molds made by Tassie. The artist left behind a collection of over 15,800 intricate pieces of artwork. Many of Tassie’s intaglios were cast in glass-paste or plaster, which could eventually break. However, some were cast into bronze—which have survived for centuries. These pieces are rare treasures that capture Tassie’s incredible skill. 

The medallion weighs 13.7 grams. It measures approximately 1” x 3/4” with a 7.4mm round bail. The bezel and bail have been recently added and are 18k gold; the bezel is marked as 18k on the back.

The medallion is pictured here on a Tiffany & Co. angular link chain, with our Signature 14K Gold Victorian Shepherd’s hook charm holder. We’ve also used this medallion as a mold for our Signature Collection and have a 14k gold version of the pendant available in our shop.

Smaller than expected.
Size: 8 cube
The directions were complicated with only image directions. One person can put this together. It took me about an hour. The item is smaller than I expected. The image is misleading. Definitely not waist high for an adult. More like thigh height. Guess I should have paid more attention to the measurements instead of the image. It looks nice when assembled. For the price I expected something taller.

Great for the price — OffiGo 8 Cube Organizer Bookcase, Modern Farmhouse
Size: 8 cube
I bought this for myself after reading about it online, and it's been pretty solid so far. It works as advertised for daily use and fits into our routine well. The build/quality feels good for the price, though I noticed a minor issue that you should be aware of.

Nice entry way table
Size: 8 cube, Size: 8 cube
Great-looking 8 cube organizer with a really nice finish. The color is beautiful, and the top has a slightly matte stain that gives it a clean, modern look without being too shiny. Assembly does take two people at certain points, as you’ll need someone to hold pieces in place while aligning and securing them. Not difficult overall, just easier with an extra set of hands. It’s a bit shorter than a typical entry table, but the width is great and it offers plenty of storage space. Perfect for organizing baskets, shoes, or everyday items while still looking stylish.
