Object Description

This magnificent, large and impressive antique diamond brooch has been crafted in 18ct white gold with a platinum setting.

The brooch has been modelled in the form of an ornate flower, combining leaved stem and flower head.

The stem is channel set with twenty-six baguette cut diamonds, the curved leaves with twenty-two channel set baguette and fifty nine pavé set Old European round cut diamonds.

A single feature 0.61ct Old European round cut diamond rests between the stem and leaf within an eight claw setting.

The centre of the flower head is ornamented with a feature individually eight claw set 0.70ct Old European round cut diamond, encircled by nine baguette cut diamonds.

The seven curved teardrop shaped, pierced decorated petals are each collet set with a feature Old European round cut diamond; a 0.42ct, a 0.39ct, a 0.38ct, a 0.36ct, a 0.34ct, a 0.33ct and a 0.29ct.

The scalloped edged petals are embellished with a further twenty-seven channel set baguette cut diamonds and one hundred and five collet set Old European round cut diamonds.

The ornate design secures to the reverse with an 18ct white gold hinged double pin fastening, hallmarked to each pin with the French import mark for 18ct gold (Owl).

The setting has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as platinum.

This antique diamond floral brooch is supplied with nine independent diamond grading certificates for the feature diamonds in addition to an independent diamond grading report card for the supporting stones.

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.
