Very rare this turquoise and diamond tulip brooch was made by David Webb circa 1970's. The flower is delicate and beautiful with a soft blue color to turquoise. As with all natural and genuine turquoise it tends to have natural blemishes and discolorations. This turquoise has a few blemishes however not prominent to the naked eye. Diamonds are round and baguette in shape and are estimated G-H color, VS1-VS2 clarity. The brooch fastens with a double pin closure. It measures 3.1 inches. This is a beautiful vintage item and we do not recommend to polish it. Center Diamond Weight: 0.00 Measurements: L: 3.1inches Metal Type: Platinum & 18K Yellow Gold Metal Weight: 29.4 gr.
