Catherine has a particular love for Paraiba Tourmaline and it is her all time favourite gemstone. She finds the colour absolutely mesmerising; its rarity and the quality material she works with, just make it even more special. It has a good hardness on the MOHS scale making suitable for wear in all types of Jewelley. Catherine loves the combination of diamond in white colour metals to really show off the rich colour of the gemstone.
Catherine finds it a very spiritual gemstones and reminds her vividly of the beautiful tropical seas of the world, ultimately though it just leaves her with a feeling of happiness.
