Edwardian 5.88 Carat Diamond Star Brooch – Circa 1910

A stunning, fine and impressive antique Edwardian 5.88 carat diamond, silver and 14 carat yellow gold set star brooch; part of our diverse Edwardian jewellery collection

This stunning, fine and impressive diamond brooch has been crafted in silver with a 14ct yellow gold fastening.

The tiered stellate design is ornamented with a feature central claw set 0.78ct Old European cut diamond.

The feature diamond is encompassed with eight claw set Old European round cut diamonds.

The eight floriated-style points of the brooch are each embellished with six pavé set Old European cut diamonds, graduating in size dependant on location.

The tiered stellate style setting is further ornamented with eight protruding collet set Old European round cut diamonds, bearing plain stems, completing the design.

This versatile brooch secures to the reverse with a detachable 14ct yellow gold hinged pin and clasp fastening; the detachable fastening enables the piece to be converted into a pendant if required, in addition to indicating the high quality of the piece.

This stunning Edwardian diamond brooch has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as silver and 14 carat gold.

This impressive brooch is supplied with an IDGL diamond grading report certificate for the feature stone, in addition to an IDGL diamond grading report card for the supporting stones.

Such examples with a combination of larger high quality diamonds are becoming increasingly difficult to locate.

This Edwardian diamond star brooch is an elegant gift for milestone birthdays and anniversaries. Its celestial motif symbolises guidance and admiration, making it ideal for a mentor, partner or mother.

This stunning antique brooch is exceptional quality, set with a stunning diamond displaying a fine white colour, brilliance and presence.

The supporting evenly colour matched diamonds display a fine white colour and brilliance; although some of the diamonds are clarity graded at P1, they show no unsightly black inclusions.

This multi-diamond brooch is an exceptional gauge of gold and silver, and is in exceptional 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.
