Tanzanite tourmaline & diamond platinum & 18ct white gold necklace

This absolutely fabulous necklace has been designed by Alan and he also cut the tanzanite and tourmaline from rough material that he has had for some time. Let's begin at the top! The top section consists of a pear shaped tanzanite set in a mille-grained platinum setting into which small round diamonds have been set to form a frame around the top of the tanzanite. On each side of this section is a round platinum diamond set setting into which the 18ct white gold Spiga chain has been fixed. Suspended from the tanzanite setting in a mille-grained platinum tube setting is a round diamond and suspended from this is the platinum drop section. The drop section consists of a pear shaped pink tourmaline in a mille-grained platinum setting into which small round diamonds have been set to form a frame around the bottom of the tourmaline.
The necklace has been hallmarked by the London Assay Office for platinum and 2016 and bears the sponsor's mark "A&SP" for Alan & Sue Poultney.
