The exposed areas of gold have a soft "bloomed" finish typical of higher quality Art Nouveau jewels that constrasts beautifully with the translucent enamels. The back is stamped "14K" and is engraved "COMUS 1908."

The Mystick Crewe of Comus is the oldest and most exclusive of New Orleans' Mardi Gras organizations...

Art Nouveau 18K yellow gold wide chain bracelet with ruby clasp, circa 1900. Very rare piece. This bracelet is made of 9 rows of 18K gold chains divided in to 5 sections by 4 gold bars. Each chain has 2 ornate links with a beautiful art nouveau motif per section, but each successive row is made a bit wider than the one above it by additional tiny round links in the center of each section (see photo). This makes the bracelet longer at the bottom (9 3/8 inches) than at the top (7 inches)...

The quiver’s strap is set with small rose cut diamonds for an added bit of sparkle. The name “Amor” is included in the design to the left of Amor’s head...

The fairly large oval topazes are surrounded by swirls of seed-pearl-set gold, and set off by 4 bright green garnets, two of which are set into the fine chains which connect the top section to the bottom; of the other two, the top one is a modified pear shape, the other is oval.

A stunning Art Nouveau 14K yellow gold pansy pin enameled in rich shades of dark plum, violet, cream and saffron. The jeweler used a matte enamel to suggest the velvety texture of pansy petals. The flower is centered with a prong-set round cut diamond that adds a nice sparkle against the matte enamel. The back of the pin is marked for 14K and also has a maker's mark that we've not seen before. The pansy is most definitely a Newark or New York piece and is very similar to pansies by Hedges an...

Her hair cascades down to her shoulder, and gold disks hang from the crown. There is a tiny dent at about cheek bone height. The back has a monogram, perhaps an S, and has several little dents, which are highly exaggerated in the photos. The rose gold (it was very hard to photograph the color accurately) tests at about 12k. I...

A wonderful Victorian/Art Nouveau pendant and brooch in the form of a mythological griffin grasping a diamond in its jaws. The creature’s open-winged pose is somewhat unusual for this type of jewel, as they tend to be more curled up in a more circular position. The pose, however, makes for wear as a dramatic pendant hanging from the pendant loops on each wing. The back also has a removable fitting so it can also be worn as a brooch. And finally, there is a watch hook at the bottom that could s...
