2.80ct Emerald, 1.75ct Ruby, 2.10ct Sapphire, 0.26ct Diamond and 18ct Gold Window Brooch by Gubelin - Vintage Circa 1950


A stunning, impressive and unusual vintage 2.80 carat emerald, 1.75 carat ruby, 2.10 carat sapphire and 0.26 carat diamond, 18 carat yellow gold and 18 carat white gold window brooch made by Gubelin; part of our diverse gemstone jewellery and estate jewelry collections

SKU C8616

This stunning and unusual vintage brooch has been crafted in 18ct yellow gold and 18ct white gold settings.

The brooch has been modelled in the form of a window with flowers, behind a wrought iron grille.

The anterior portion of the brooch is embellished with an impressive 18ct white gold pierced decorated frame, replicating the curvilinear scrolling ornamental grille of the window.

This finely crafted vintage brooch is embellished with five sapphires, ten rubies and six emeralds; each individually set mixed cut gemstone bears carved details replicating the organic details of the floral spray.

The gemstones array incorporates impressive individually claw set transitional modern brilliant round cut diamonds.

The spray is further embellished with two claw set round faceted cut yellow gemstones*, providing further visual dynamic to the piece and completing the design.

This floral brooch secures to the reverse with a hinged double pin and push fit clasp.

The reverse of the frame is hallmarked with the 18ct gold mark (750) and the maker's mark (Gubelin); this brooch is an exceptional example, as to be expected with items crafted by this renowned goldsmith.

This stunning multi-gemstone brooch is supplied with an IDGL diamond and gemstone grading report card.

Such unusual gemstone brooches are rare to the market.

NOTE: * Due to the nature of the caged grille design these yellow gemstones could not be identified or measured by a gemologist without disrupting the original gold frame; it has been determined with the testing available that these are citrines, with a strong probability.

Images do not always reflect the true colour and brilliance of gemstones and diamonds. The video however provides a truer representation of the actual colour and showcases each stone.

Maker: Gubelin

This stunning Gubelin gemstone brooch is exceptional quality, set with impressive emeralds, rubies and sapphires displaying fine colour, brilliance and presence.

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

The brooch is an exceptional gauge of gold and is in exceptional condition, with very clear hallmarks to the reverse of the setting.

Reflections in photographs may detract from the true representation of this stunning, unusual rare gemstone brooch.
