Scottish Sterling Silver Cairngorm Brooch with Citrine and Thistle

• Sterling Silver - Sterling silver is a mixture of 92.5% pure silver and 7.5% of another metal, usually copper. Fine silver is 99.9% pure silver, and is relatively soft and the addition of the very small amount of copper gives the metal enough strength and hardness to be worked into jewellery, decorative and household objects.
• Faceting - Faceting is a technique of removing material from a curved surface, to give a series of flat surfaces but retaining the profile of the original surface.
  
  The technique is most commonly associated with diamond cutting where the various cuts used such as rose cut and brilliant cut, add life and sparkle to the stone, whilst at the same time removing as little of the stone as possible.
  
  Faceting by grinding is also used to decorate glass. The stems of many drinking glasses are decorated by cutting a series of flat surfaces on a circular stem, and hollow vessels such as vases may have faceted surfaces.
  
  In furniture faceting is often applied to legs of tables and chairs, where a circular baluster shaped section is flattened so as to form an octagonal section.
• Cairngorm - Cairngorm is a type of smoky quartz, which is a variety of quartz that ranges in colour from light gray to dark brown. It is found in granite rock in the Cairngorm Mountains of Scotland, hence its name, and it is typically found in large clusters. The mineral is relatively hard, with a Mohs hardness of 7, and it is fairly durable, making it a suitable choice for jewellery and decorative objects.
  
  Cairngorm is said to have spiritual and healing properties, it is believed to have grounding energy, and it is thought to help with focus and concentration. It is also said to be a stone of protection and is said to help balance the energy within the body.
  
  The mining and collection of Cairngorms is heavily regulated in Scotland, and it is illegal to remove them from the Cairngorms National Park without a permit.
