Antique French Single Strand 29.30ct Emerald and Pearl Necklace with 0.25ct Diamond Platinum and 18ct Yellow Gold Clasp Circa 1920

1900 - 1920
For Sale by AC Silver
Description

A fine and impressive antique French single strand 29.30 carat emerald and pearl necklace with 0.25 carat diamond, platinum and 18 carat yellow gold clasp; part of our diverse antique jewellery and estate jewelry collections.

This fine and impressive antique single strand necklace with diamond clasp has been crafted in 18ct yellow gold with a platinum setting.

The necklace consists of seventy-eight impressive emerald beads graduating in size and alternating with seventy-seven impressive seed pearls.

The necklace secures with an antique pierced decorated, marquise shaped push fit clasp.

The antique clasp is ornamented with three millegrain decorated collet set Old European round cut diamonds, in a linear formation.

The finely detailed clasp is further ornamented with eight pavé set diamonds, in a combination of Dutch and mine cuts, completing the design.

The tongue of the clasp is hallmarked with the French 18ct gold mark (eagle's head) and the maker's mark; and the clasp has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as 18 carat gold and platinum.

This impressive emerald and pearl necklace is supplied with an IDGL diamond and gemstone grading report card.

This emerald and pearl single strand bead necklace balances the contrast of vibrant green gemstones with the soft lustre of classic pearls, creating a look that feels both timeless and quietly distinctive. It is an elegant choice for those who appreciate subtle sophistication and is particularly well suited to daytime occasions, formal lunches, weddings or evening events where refined colour is desired without excess sparkle.

'Rather than regarding inclusions in coloured stones as harmful, in small sizes and numbers that do not in any way detract from their beauty, they should be regarded as adding to desirability, for they provide identifying characteristics.'

Reference: The Connoisseur's Guide to Precious Gemstones, R. Wise, Brunswick House Press.

Images do not always reflect the true colour and brilliance of gemstones and diamonds. The video however provides a truer representation of the actual colour and showcases each stone.

Condition

This impressive antique necklace is excellent quality, set with impressive emeralds displaying fine colour, brilliance and presence.

The impressive seed pearls display fine colour and lustre.

The high colour graded diamonds display a fine white colour and brilliance.

The clasp is a gauge of gold and platinum and is in excellent condition, with clear French hallmarks to the tongue.

Reflections in photographs may detract from the true representation of this fine example of pearl jewellery/estate jewelry.

Every single antique dealer on our platform is individually approved by our internal team. We verify their professional trade history, ethical standards, and photographic quality to ensure a secure, high-standard buying environment. Upon joining, every dealer agrees to a strict 9-point code of conduct. While issues can occasionally arise, our dealers typically resolve them swiftly and directly with the buyer. In fact, since our founding in 2002, Sellingantiques has only had to step in to help resolve an issue on roughly five occasions—a true testament to the quality of our dealers and their dedication to your happiness.
Our dealers are highly experienced in packing and shipping fragile, high-value antiques. Because you are in direct contact with the dealer, you will be able to easily go through all available shipping and insurance options together to ensure your item arrives safely.
Antiques are the ultimate green purchase. By choosing historical pieces over newly manufactured goods, you completely eliminate the carbon footprint of modern mass production while preserving exceptional, timeless craftsmanship.

Art Deco jewellery from the 1920s is characterised by geometric patterns, bold colour contrasts, and precise metalwork, often combining vibrant gemstones like emeralds with pearls and diamonds set in platinum or white gold.

Jewellery of this period frequently featured natural or cultured pearls interspersed with hand-cut gemstone beads, secured by platinum and 18ct yellow gold clasps decorated with rose or old European-cut diamonds.

Authentic pieces often showcase hand-engraved millgrain detailing on platinum settings, specific French hallmark stamps, period-correct diamond cuts, and fine craftsmanship on the reverse of clasps.

An antique gemstone necklace can serve as a focal point for formal evening wear or add contrast when worn against a clean, tailored monochrome blouse or neckline.

Store the necklace flat in a soft-lined box away from direct light and moisture, avoid contact with perfumes or chemicals, and clean gemstones gently using a dry microfiber cloth rather than liquid cleansers.
