San Francisco – The quarterly Salon Jewellery auction to be held September 30 at Bonhams in San Francisco, and simulcast in Los Angeles, will add some dazzle to fall shopping.

Leading the fabulous offerings of the sale will be a fine selection of 189 lots of jewellery from the estate of Margaret Nielsen Stiegele (1922-2013). Ms. Stiegele was the daughter of Arthur C. Nielsen, the creator of the television ratings system that became the industry standard. Margaret Stiegele was a noted jewellery collector whose passion for stylish pieces with beautiful craftsmanship was informed by her extensive world travels.

Highlights from the estate of Margaret Nielsen Stiegele will include a coloured cultured pearl, opal, paste and diamond necklace (est. $10,000-15,000); a diamond and 18 karat gold tubogas link necklace with a stylized buckle motif (est. $3,200-4,200); a sapphire, ruby and diamond peacock brooch (est. $3,000-5,000); a pink sapphire, diamond and 18 karat white gold wristwatch with a pink leather strap by Jaeger-LeCoultre (est. $3,000-5,000); and a collection of nine individually lotted, colourful and varied Hermès bracelets and a pair of ear clips, of varying estimates.

From the various owners portion of the sale, highlights will include a Riker Brothers ruby and diamond Asian dragon motif bracelet, with maker's mark, mounted in 14 karat gold (est. $4,000-6,000) and an F.J. Cooper multi-color moonstone bracelet, mounted in 18 karat gold (est. $2,500-3,500).

A grand variety of brooches will be on offer to suit a wide selection of tastes and interests. Especially notable is an enamel and diamond brooch, circa 1880, composed of an enamel portrait in a rose-cut diamond surround, backed by a starburst of rose-cut diamonds, and mounted in silver-topped 10 karat gold (est. $3,000-5,000), and a diamond, ruby and sapphire ballerina brooch (est. $2,000-3,000).

Pendant highlights will include a fancy yellow diamond and diamond pendant (est. $5,000-7,000); a McTeigue & Co., coloured cultured pearl and diamond circle pendant that doubles as a brooch (est. $3,000-5,000); and an amethyst, diamond and cultured pearl floral motif pendant (est. $2,000-3,000).

Also special in the sale will be a signed, French Cartier diamond "double C decor" ring, 2000 (est. $1,500-2,500) and a set of four Bulgari gem-set and diamond B.zero1 eternity bands (est. $4,000-6,000).

Lynne Arkin, Fine Jewellery Specialist at Bonhams San Francisco, says of the auction: "This is a very interesting and inviting sale with a rich variety in every jewellery category. Special signed pieces along with unusual pieces create this attractive sale."
