The September Important Jewelry sale expands on an already impressive 2016 with a large array of fine diamonds and colored stones, signed jewels, important antique works and modernist style jewelry.  Highlighting the sale are signed items by Tiffany & Co., Cartier and Oscar Heyman Brothers, as well as a 6.40 carat antique cushion cut Kashmir Sapphire and a 2.58 carat oval mixed cut fancy orangy pink diamond. The two day auction will also include a broad selection of antique and vintage jewelry, spanning from the Georgian to Art Deco periods. 

Signed Jewelry.

The September Important Jewelry auction offers an opportunity to acquire important jewels from such luminaries as Louis Comfort Tiffany, Jean Schlumberger, Cartier, and Julius Cohen amongst many others.  Representing the strong antique theme of the session, an elegant platinum, aquamarine and diamond necklace by Tiffany & Co. graces the cover of our catalogue.  Its complex and delicate platinum work strongly suggests a connection to Louis Comfort and possible Meta Overbeck.  Leaping forward in time, the beloved work of Jean Schlumberger is well represented, most notably so in an example of his “Leaves” bracelet in platinum, gold and diamonds.  Not to be missed are a pair of important emerald and sapphire pendant earrings by the grande maison Cartier.  Works by the venerable Julius Cohen are also featured, including an impressive pair of unheated sapphire earclips in their signature flower motif as well as a sumptuous and bold brooch set with Burmese sapphires and fine aquamarine.

Antique and Estate Jewelry

Our curated presentation of several important private collections in the September session has led to a broad and wonderful selection of antique and vintage jewelry.  Age, rarity and fine condition are all exemplified in a pristine Georgian gold repousse link bracelet containing vivid green emeralds and old mine cut diamonds.  Centered around a noteworthy drop shape natural saltwater pearl over 16.00 mm in length, a featured Art Deco platinum and diamond necklace makes quite the impression.  Seldom seen carved from fine gems, an emerald cameo brooch set in an early Deco-inspired circular mount turns the typical notion of cameo jewelry upside down.  Finally, a delicate convertible silver topped gold and diamond tiara/necklace dating to the Victorian period is a perennial favorite.

Important Color Jewelry

The colored gem selection in September is amongst the most compelling we have ever offered.  A extraordinarily rare, doubly certified 6.40 carat cushion cut Kashmir sapphire sourced from the important Schoonmaker collection exudes the velvet, azure blue that makes these gems the most sought after.  Another favorite, Colombian emeralds are well represented in the sale and none of higher quality then a classically simple three stone emerald and diamond design containing a square octagonal step cut center stone with insignificant clarity enhancement.  New to some, the “electric” teal hue of our classic Brazilian Paraiba tourmaline grabs the attention of its viewer and begs the question of how such a color can exist in nature.
