Prehnite is not a gemstone that is very often used in Jewellery because the colour is so variable       and so there is not enough consistency to be workable.  When I saw this long Prehnite polished      drop Strand I fell upon it as I think it makes the most wonderful long Necklace.  With a generous        length of approximately 90cm (35") which enables you to wear this necklace as one long necklace  or doubled up making it two strands.  It drapes beautifully, allowing you to showcase the unique,      translucent green hues of each polished drop.
