Object Description

A very fine, late 19th Century, Belle Époque, Diamond Necklace, which also converts to an extraordinary Diamond Tiara, set in High Carat (18 Carat Tested), Yellow Gold and Silver (925).

The central feature of this noble piece is a Diamond set classical fan shaped spray, which is flanked by two symmetrical Diamond set Demi-scroll sprays, these are then suspended from a detachable trace necklace, comprising of alternating graduating linear and navette shaped Diamond links, the necklace then closes with a matching sprung tongue Diamond set clasp.

This remarkable and historic necklace is centrally claw set with a single Old European Cut Diamond, which has been independently assessed as being of 1.17 Carats, H Colour and SI1 Clarity. There are a further 281 Old Cut and Rose Cut Diamonds throughout (some of substantial size), these have been assessed as being of 15.50 Carats, G – J Colour and VS2 – SI2 Clarity. The total Diamond weight of this stunning piece has been independently assessed (while within mounts & settings) at 16.67 Carats, overall.

The central section of the Necklace / Tiara is detachable, so that it may independently be worn as a substantial Diamond Brooch, The detachable Brooch fitting is concealed within its lined Collingwood necklace case (assumed to be the original case).

Were restoration is concerned, there is slight evidence of an earlier extension to a couple of the links, near to the necklace clasp; presumably to make this a more generous fit (necklaces of this period usually sat higher on the neck or were worn in the “choker” style). Furthermore, a bespoke Tiara frame has been acquired, which sympathetically matches and mirrors the existing fittings on the reverse; thereby restoring the option for this piece to be worn as a beautiful Diamond Tiara (as originally intended). Apart from the above there is little evidence of any other alteration or restoration.

For transportation purposes, a separate bespoke fitted case has been commissioned to accompany the Diamond Tiara and frame. Furthermore, an independent Gemmologist’s report confirming the above Diamond grading and assessments also accompanies this piece.

Convertible Necklaces & Tiara’s have enjoyed a global resurgence in recent years and the availability of this unique piece presents a rare opportunity for an avid collector and connoisseur to add a versatile and beautiful example of fine Belle Époque Diamond Jewellery to their collection.
