Lot 0255
Pilgrimage Icon of Saint Catherine the Great Martyr on Stone, Palestine, late 19th century
Estimate: 5000-7000€Pilgrimage Icon of Saint Catherine the Great Martyr. Palestine, late 19th century. Stone, oil paint. Dimesniosn: 14.5 × 11 cm.
A pilgrimage icon painted on a naturally shaped stone plaque, depicting Saint Catherine the Great Martyr standing full-length against a simplified landscape ground. The saint is shown crowned and haloed, vested in richly ornamented garments, with her traditional attribute of the martyr’s wheel placed beside her. The irregular contour of the support, together with the plain reverse fitted with a suspension loop, preserves the character of the object as a devotional souvenir brought from the Holy Land.
Such icons, acquired by pilgrims in Jerusalem and other sacred places, held a particular place in Russian Orthodox devotional culture. They functioned not only as commemorative eulogiae, but also as intimate objects of private piety. Kept in domestic icon corners, donated to churches and monasteries, or handed down as family relics, they were valued for their direct material connection with the sacred geography of Palestine. In works of this kind, the tangible substance of the stone itself, often believed to have come from the banks of the River Jordan or other holy sites, intensified the devotional meaning of the image and transformed a modest painted object into a cherished relic of pilgrimage.Starting price: 4000€

Lot 0254
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€
