Art Deco Style Platinum, Aquamarine and Diamond Pendant Necklace
Estimate: 25000-30000€Art Deco Style Platinum, Aquamarine and Diamond Pendant Necklace
An impressive platinum pendant necklace of strongly geometric Art Deco style, centered by a large emerald-cut aquamarine within an architectural diamond-set frame, the stepped outline further enriched with diamond-set side panels and a diamond-set articulated surmount. The pendant is suspended from a platinum chain with decorative openwork links, complementing the period-inspired design.
The reverse and side views show pierced and millegrain-style detailing characteristic of high-quality geometric jewel mounts. The clasp appears marked 950, consistent with platinum fineness, while the accompanying 2008 appraisal describes the jewel as solid platinum.
Accompanied by a 2008 Dover Diamonds Appraisal, which describes the necklace as set with one genuine blue aquamarine of approximately 40.00 carats and 90 European-cut diamonds of approximately 4.50 carats total, graded H–I color, VS clarity; the appraisal also notes a gross weight of approximately 28.7 grams, pendant length of about 2¼ inches, chain length of about 20 inches, and an appraised value at that time of USD 17,500. A separate gemmological note in Estonian appears to repeat broadly similar information, including aquamarine, diamonds, approximately 40 pcs, H/I color, VS clarity, and a combined stone weight notation around 4.50 ct, but this handwritten note is not fully legible in all parts. These documents are useful supporting papers, though I cannot independently confirm the exact stone weights, natural origin, or grading without a modern gemmological report.
Material: platinum
Stones: one large emerald-cut aquamarine, numerous diamonds
Pendant length: approx. 2¼ in. / approx. 5.7 cm
Chain length: approx. 20 in. / approx. 50.8 cm
Weight: approx. 28.7 g
Auction Comparison:
For comparison, Bonhams sold an Aquamarine and Diamond Pendant/Necklace, circa 1940 in the Knightsbridge Jewels sale on 26 November 2025 as Lot 361, for £20,480 including premium. Bonhams described that example as set with a step-cut aquamarine weighing approximately 27.70 carats and diamonds totaling approximately 3.00 carats. By contrast, the present necklace is accompanied by an appraisal describing its aquamarine at approximately 40.00 carats, indicating a substantially larger center stone than the Bonhams example.Starting price: 20000€

Knut-Oskar Pihl (1860–1924) was a Finnish jeweler and head master of the Moscow branch of the House of Fabergé between 1887 and 1897. At the age of six, Pihl was sent from Finland to St. Petersburg to live with his uncle, a watchmaker. He later trained in the workshop of the renowned Finnish jeweler August Holmström. His skill and precision so impressed Holmström that in 1887 he arranged the marriage of his daughter Fanny to Pihl and recommended him to Carl Fabergé.

Estimate: 10000-15000€Art Nouveau Style Gold, Opal Matrix and Gem-Set Cameo Brooch Pendant
An unusual gold brooch pendant designed as an openwork oval frame enclosing a female profile cameo, carved in opal matrix with vivid blue iridescence and set against a darker natural stone ground. The flowing mount is highlighted with seed pearls and further accented with coloured stones, including pink and blue gems and a small green stone. The reverse fitted with a brooch pin, while the suspension loop allows the piece to be worn also as a pendant.
The reverse bears a 585 mark, indicating 14 karat gold.
Accompanied by an older handwritten gemmological note in Estonian. According to this note, the piece was described as set with opal matrix, pearls, rubies, a garnet, a blue sapphire, and small diamonds; this attribution is not independently confirmed and should be treated as provisional pending modern gemmological examination.
A decorative and distinctive jewel, likely inspired by late 19th- to early 20th-century Art Nouveau models.
