Vintage 302ct Citrine / Coloured Quartz and Diamond, 18ct Yellow Gold Necklace

A stunning, fine and impressive 302 carat citrine/coloured quartz and 0.20 carat diamond, 18 carat yellow gold necklace; part of our diverse vintage jewellery and estate jewelry collections

This stunning, fine and impressive vintage gemstone necklace has been crafted in 18ct yellow gold.

The medial point of the necklace is embellished with a chain style drop incorporating two coloured quartz flanking a citrine, all as tumbled stones.

This exceptional drop is suspended from a circular yellow gold setting ornamented with thirty-one modern brilliant round cut diamonds.

Either side of this central arrangement is ornamented with seven further tumbled stones in a combination of citrine and coloured quartz.

Each stunning gemstone is conjoined with chain links and suspends from a yellow gold chain securing with a lobster clasp.

This clasp is hallmarked with the maker’s mark (Stenzhorn), the 18ct gold mark (750) and the diamond carat mark (D0.20).

This vintage gemstone necklace has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as 18ct.

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

This vintage gemstone necklace is suited to bold and celebratory occasions. Citrine is traditionally associated with positivity, success, and prosperity, making the necklace particularly appropriate for milestone birthdays, career achievements, anniversaries, or major personal celebrations.

This stunning vintage women’s necklace is excellent quality, set with stunning gemstones displaying fine colour, brilliance and presence.

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

The necklace is an excellent gauge of gold and is in excellent condition, with clear hallmarks to the lobster clasp.

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.
