Antique 3.20ct White Opal and 0.25ct Diamond 18ct White Gold Ring Circa 1925

1900 - 1920
For Sale by AC Silver
Description

A stunning, fine and impressive antique 3.20 carat white opal, 0.25 carat diamond, 18 carat white gold and platinum set ring; part of our diverse opal jewellery collection.

This stunning, fine and impressive antique antique white opal ring has been crafted in 18ct white gold with a platinum setting.

The claw setting displays a feature central 3.20ct oval cabochon cut white opal.

The pierced decorated, bifurcating ring shoulders are embellished with eighteen pavé set eight cut diamonds, integrating with the main setting and amalgamating to form the plain ring shank.

This finely hand crafted, low set ring is hallmarked to the interior of the shank with the platinum mark (PLAT) and 18ct gold mark (18CT).

The ring is supplied with an IDGL diamond and gemstone grading report card.

This 1920s white opal ring with diamonds in platinum is especially suited to anniversaries, birthdays or meaningful romantic gestures, where its luminous opal and diamond accents create a refined balance of softness and brilliance. Its fine craftsmanship and platinum setting also make it an inspired self-purchase for those drawn to opal gemstones and elegant period design.

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 dress ring is excellent quality, set with an impressive opal displaying a scintillating play of colour and presence; the predominant red overtones are highly desirable.

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

The ring is an excellent gauge of gold and platinum, and is in excellent condition, with clear hallmarks to the interior of the shank.

Reflections in photographs may detract from the true representation of this fine example of opal jewellery.

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 opal rings from the 1920s combine natural iridescent gemstones with geometric metalwork, typically crafted in white gold or platinum to reflect the modern aesthetic of the era.

Rings from this era were frequently constructed using 18 carat white gold or platinum settings, housing central cabochon gemstones framed by small brilliant-cut or single-cut diamonds.

Authentic pieces feature period-correct metal hallmarks, hand-set accent stones, precise geometric gallery construction, and subtle hand-engraving details indicative of early 20th-century craftsmanship.

An antique opal ring functions as a statement piece worn individually on the hand, or paired with minimalist fine metal bands to highlight the gemstones colour play.

Opals require delicate care using soft damp cloths without harsh chemical cleaners, ultrasonic immersion, or sudden temperature variations, as the stone contains natural water content.
