We had a visit from one of our favorite clients, Chris, his wife Jaybee, and friends, on their way to a special event celebrating the Riverside Dickens Festival. We were pleased to see Jaybee wearing the exquisite antique necklace Chris recently acquired from Mardon. This necklace is one of the finest examples of Edwardian jewelry it’s been our […]
The Polygon Trading Network, an online buying/selling service for the diamond trade, announced the latest bombshell in the EGL Diamond Grading scandal. They will no longer list diamonds with European Gemological Laboratory International (EGL) reports. This follows in the wake of the decision by another trading network, RapNet, to ban all EGL report for it’s […]

We acquired this highly unusual Art Deco Pools of Light necklace almost by accident. We recently purchased an estate of wonderful early 20th century jewelry items, mostly rings and pins. This piece and another interesting rock crystal necklace were included in the group. Since they had no gold content, we didn’t think too much about […]
We recently completed the resurrection of a ring that had been severely damaged. Fine jewelry is made from precious materials that when properly cared for, will last for centuries. Gemstones are durable and ancient– diamond crystals are typically 1 to 2 billion years old. Gold is eternal. It doesn’t deteriorate and is never discarded– if a style or […]
A client inherited this gorgeous antique Yogo Sapphire pin and asked us to appraise it. Sapphires were known to occur in several areas of western Montana as early as 1865. For the most part, these deposits produced only moderately good sapphires. The discovery of sapphires in Yogo Creek was different. In 1895, famed gemologist G.F. […]
We were thrilled to acquire this pendant featuring an authentic Piece of Eight silver coin from the most valuable sunken treasure ever found. In 1985, after 16 years of searching, famed (and persistent) treasure hunter Mel Fisher discovered the mother lode of all treasures off the Florida Keys. Valued at over 500 million dollars, the Atocha treasure […]
We recently had the pleasure of examining this superb antique chatelaine. Centuries ago, the lady of the house wore the chatelaine, a strap or bag looped over a belt at the waist. Typically, the various tools necessary for her to deal with her daily tasks, items such as keys, scissors, watches, etc. were attached with chains. During the last half of […]
This exquisite necklace from the Edwardian period, circa 1900-1915, exhibits the fine craftsmanship we associate with antique jewelry. The piece was made by fabricating and forming raw metals into the parts of the jewel. The main body and dangles began as thin sheets of platinum. The chain and bezels were made from hand-drawn wires and […]
