37.03ct Aquamarine and 11.54ct Diamond, 18ct White Gold Necklace – Contemporary (2012)

A stunning, fine and impressive 37.03 carat aquamarine and 11.54 carat diamond, 18 carat white gold necklace; part of our luxury jewellery collection

This fine and impressive contemporary aquamarine and diamond necklace has been crafted in 18ct white gold.

The stunning contemporary design is ornamented with twenty-one stunning oval faceted cut aquamarines, conjoined in a row.

Each aquamarine is encompassed with a cluster of twenty pavé set modern brilliant round cut diamonds, accented with semi-circular settings to either end, each incorporating six further diamonds.

These cluster designs conjoin via a horizontal pale, each embellished with further five pavé set diamonds, completing the design.

The necklace secures to the reverse with an integrated push fit clasp, and benefits from the added security of a safety clasp.

The aquamarine necklace is hallmarked to the reverse of the clasp with the maker’s mark (JT), the crown, the 18ct gold mark (750, K18), the London Assay Office mark (leopard’s head), and the date letter for 2012 (n).

The surface of the safety catch bears the marks denoting the carat weight of the feature gemstones (37.03) and supporting diamonds (D11.54).

This impressive statement jewellery piece is supplied with an IDGL diamond grading report card.

This diamond and aquamarine necklace in white gold is best suited to occasions that celebrate love, tranquillity and life’s most meaningful milestones. The gemstones create an elegant and timeless piece that is particularly appropriate for milestone birthdays, anniversaries, weddings, bridal gifts, Mother’s Day or significant personal achievements.

Although we specialise in antique and vintage jewellery, we occasionally include only the finest contemporary pieces within our collection, such as this exceptional example.

This impressive necklace is excellent quality, set with stunning aquamarines displaying fine colour, brilliance and presence.

The impressive 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 reverser of the catch.

I have dealt with AC silver on several occasions

I have dealt with AC silver on several occasions and always found Andrew extremely knowledgable and trustworthy. Nothing is too much trouble and I am absolutely delighted with my last purchase of a 5 stone diamond ring. From start to finish the process was extremely easy and everything catered for. It was a pleasure to del with Andrew and his most helpful and charming Assistant.

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.
