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.

Award winning tuxedo!
Size: Large, Color: Baby Pink, Size: Large, Color: Baby Pink
Love this tuxedo suit! I’ve worn it a few times - to two different weddings and an Academy Awards viewing party, where I even won for best dressed. I get so many comments on it. The jacket and vest fit perfectly, however the pants are long and I had to hem them, but “stitch witchery” tape worked fine. The pants are also a little “stiff” - not a smooth fabric. But for occasional wear, it’s fine! The bow tie was sold separately.

Slim fit
Size: Large, Color: Brown
I recently purchased the brown slim-fit suit and am very impressed! For reference, I’m 6’2” and 222 lbs, and while I usually wear a size large, I went with an XL based on the fit advice and it was the perfect choice. This suit does run a bit small, so ordering a size up is definitely the way to go. The slim fit is flattering and modern without being restrictive, and the rich brown color adds a unique and stylish touch to any occasion. The material feels high-quality, and the overall craftsmanship is excellent. If you're looking for a sharp, well-fitting suit, this one is a fantastic option—just be mindful of the sizing!

Good Decision !
Size: Large, Color: Dark Black, Size: Large, Color: Dark Black
Upon receiving the suit we were definitely skeptical because certain materials don't match the pictures. But Baby when we say this one came and showed up. It was great material , not cheap feeling if you get what Im saying. The pants, jacket and vest all came as it said it would. Nothing was missing! It came pressed and very wrinkle free so it was taking care of prior to shipping out. We got a Large for my son because of course he wanted a slimmer fit. But it did work out. He had enough room to comfortably be able to move. And for it truly was a steal for how much it costed. This literally felt like it was suppose to cost a few hundred , but it was so affordable.
