Victorian Antique Scottish Hardstone, Rock Crystal Cross Large

Magnificent and scarce antique 19th Century Scottish sterling silver hardstone cross 3 inches tall and 2 inches across the arms, set with carnelian, bloodstone and 6 foiled back rock crystal cabochons to appear to be amethyst or citrine, I assume the latter are to illustrate the 6 wounds of Christ. It is exceedingly well made and the only fault is that some of the foil backing the rock crystal cabochons has lost colour, it also has the original faceted suspension loop. Not marked in any way as is normal for a item of Scottish jewellery of this era.
