Very finely cut Swiss Blue Sapphire encased in 18 Kt White gold over .925 silver Necklace about 2 x just under 2 cm with zirconia surround in teardrop shape. It is truely an exquisite piece, and one of my better picks for sale. Only the one available. They are all hallmarked as completely genuine 18 Kt white Gold coated over .925 silver As a dress necklace, it looks very much like the real thing, and all will wonder how you could afford such a beautiful expensive piece like this. In no way it looks "Junky". I hand select all my jewellery, and offer them all in very limited supply from 1-4 of everything I hand select and import. As with much of this jewellery, please be aware staining occurs if you spray on perfume directly onto any of the jewellery. Kept clean, and for special occasions, will last you many years.
