Vintage Cultured Pearl and Black Diamond and White Diamond Pendant

A stunning, fine and impressive vintage cultured pearl and 37.05 carat diamond, 18 carat oxidised white gold necklace; part of our diverse vintage floral jewellery collections

This extraordinary vintage necklace has been masterfully crafted in 18ct oxidised white gold.

The pendant features four articulated five-petal floral motifs, gracefully graduating in size to create a fluid and elegant drop. The central flower displays a magnificent 10.49mm cultured pearl, radiating a soft, luminous glow at the heart of the design.

Each petal is pavé set with an array of round faceted black diamonds, accentuated by clusters of white diamonds that create shimmering highlights and definition. The three upper floral motifs echo this exquisite composition, each centred with an ornate floriated white gold setting adorned with six modern brilliant-cut diamonds for added sparkle and sophistication.

Suspending elegantly from a strand of faceted black diamonds, the necklace secures with a hallmarked 14ct gold push-fit clasp, further embellished with a lustrous cultured pearl to complete the design.

The reverse of the pendant bears full London assay marks, including the maker’s mark ‘BON’, the 18ct fineness mark (750), the leopard’s head for the London Assay Office, and the 1964 date letter ‘i’. Independently tested and verified using advanced Niton XL2 Analyzer technology, this piece is confirmed as 18ct gold and supplied with an IDGL diamond and gemstone grading report card.

A statement of timeless glamour, this vintage necklace perfectly balances bold design and refined elegance. Ideal for black-tie occasions, anniversaries, or as an unforgettable gift, it is a truly captivating jewel that celebrates individuality and sophistication.

This stunning vintage gemstone necklace is excellent quality, set with a stunning cultured pearl displaying fine colour, lustre and presence.

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

The vintage necklace is an excellent 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.
