Kupittaan Kulta silver and labradorite torque and pendant

A rare  museum quality  huge Kupittaan Kulta silver and labradorite torque and pendant
Set with a beautiful labradorite shimmering with light and colour,  measuring 1.6 cm in diameter this exquisitely made massive Kupittaan Kulta pendant measures 8.7 cm long  3.8 cm wide at its widest and approx 2 cm deep.It weighs 52.6 grams. 
There is a ring at the back of the pendant through which the torque slips to keep it central when worn.
The pendant is fully marked with the anvil mark  925S  Finland  NB (maker) and London import marks for 1974.
The torque measures 14 x 14 cm (adjustable of course) and is similarly marked with the exclusion of the import date letter (t). 
This is almost certainly a unique piece and is the most breathtaking piece of modernist jewellery that I've have seen in over 20 years of jewellery trading.
It's in excellent condition with minor surface wear mostly to the reverse.
One of those occasions when one can say "the chance of a lifetime" and mean it.
A must for collectors of Kupittaan Kulta!
