Antique Ruby and 0.96ct Diamond, Onyx and 18ct White Gold Bar Brooch

An impressive antique 0.15 carat ruby and 0.96 carat diamond, black onyx and 18 carat white gold bar brooch; part of our diverse antique estate jewelry collections

This fine and impressive antique bar brooch has been crafted in 18ct white gold.

The bar brooch is ornamented to the centre with the ‘Patriarchal Cross’ or ‘Cross of Lorraine’, embellished with fourteen channel set French cut rubies.

The pierced decorated, shaped frame that surrounds the central two-barred cross is accented with eight pavé set eight-cut diamonds, and framed by a border composed of twenty calibre cut black onyx.

The bar to either side of the central setting are set with a further eighteen pavé set eight-cut diamonds, and four calibre cut black onyx to the terminals.

The 1920s antique brooch secures to the reverse with a hinged pin and push fit clasp.

This antique diamond and ruby bar brooch has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as 18ct gold.

The bar brooch is supplied with an independent diamond grading report card.

A brooch of this distinctive nature makes a thoughtful gift for special occasions such as anniversaries, notable birthdays or meaningful celebrations. Its combination of symbolism, colour and styling makes it particularly suited to someone who appreciates jewellery with character and historical interest. Elegant yet striking, this piece offers both decorative appeal and individuality.

This impressive antique brooch is fine quality set with rubies, onyx and very well colour matched, very high colour graded diamonds.

The brooch is a very good gauge of gold and is in excellent condition.

Lovely selection & excellent service

AC Silver has a stunning selection of antique and vintage items. Both of my brooches arrived right on time as indicated by the tracking. They are even lovelier in person and I look forward to wearing them for decades to come. Andrew and Gemma provided excellent communication and prompt dispatch. I would absolutely recommend working through them.

Excellent customer care.

I had to place the order over the phone as my internet was misbehaving. The lady who I spoke to could not have been more helpful and was particularly careful to get all the details correct. I was then informed about the collection and dispatch of the item purchased, by email. The item arrived as expected and it had been most well packed so that no harm could come to it. It was a delight to purchase this item from C6323, AC Silver, and I could not fault any aspect of their customer care. I was highly delighted with my silver mustard pot and it was much better than the pictures on the web site.
