Antique 4.48 Carat Diamond Drop Pendant Necklace in Platinum

A magnificent, stunning, fine and impressive antique platinum and 4.48 carat diamond necklace; part of our diverse 1920’s diamond jewellery collections

This magnificent antique diamond pendant necklace has been masterfully crafted in platinum and showcases a stunning 3.85ct Old European cut diamond individually collet set within a millegrain decorated frame.

The feature diamond is suspended from a linear drop accented by a second collet-set Old European cut diamond, adding graceful movement and brilliance.

The linear arrangement suspends from a millegrain decorated collet style setting, which displays a further Old European round cut diamond completing the refined vertical arrangement.

The diamond pendant is suspended from an integrated 17.5″ platinum trace chain via two integrated ring loops to the upper border.

Independently tested using advanced Niton XL2 Analyzer technology, this magnificent diamond necklace is verified as platinum and supplied with an independent diamond grading certificate for the principal stone, along with a report card for the supporting diamonds.

Antique pendants featuring large Old European cut diamonds of this calibre are increasingly rare and highly sought after.

This stunning example of antique jewellery is supplied with an independent diamond grading report certificate for the feature stone, in addition to an independent diamond grading report card for the supporting stones.

Such an antique piece, featuring a large diamond terminal, is becoming increasingly difficult to locate.

This antique diamond pendant makes an extraordinary gift for milestone anniversaries, engagements, significant birthdays, or black-tie occasions. Its exceptional craftsmanship and remarkable centre stone also make it a treasured choice for collectors and connoisseurs alike.

The stunning 1920 necklace is exceptional quality, set with a stunning very high clarity graded principal diamond displaying a fine white colour, brilliance and presence.

The well colour matched, high colour graded supporting diamonds display a fine white colour and brilliance

This magnificent antique diamond pendant is an exceptional gauge of platinum 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.
