Highly sought after, a gift containing a ruby makes the perfect gift for any lover, effortlessly representing beauty and intense desire. 

Most notably, world-renowned jeweller Roberto Coin uses rubies as a hallmark for each of their unique pieces. A small ruby is inlaid in each of their pieces, tying together each of their collections with a stylish signature.


Sapphire ring

Deep blue sapphires make an eye-catching and unique gemstone. The birthstone of September, sapphire has regal and highly sophisticated associations. Princess Diana’s blue sapphire ring is one of the most recognisable pieces of jewellery in the world, most recently being worn by Kate Middleton after it was passed down to Prince William and used for the royal couple’s engagement.

The natural beauty of this stone represents truth, nobility and romance. A rare stone; it is reserved for only the finest of pieces and frequently makes a perfect gift for “something blue” for one’s wedding day.



Deep, vivid shades of green are the most recognisable characteristic of emeralds. With such an individual appearance, they have been highly revered across many cultures for centuries, from the Aztecs to the ancient Egyptians. The birthstone of May, emeralds remain some of the most popular gemstones and are commonly associated with royalty, wisdom and peace.


A variety of quartz, amethysts are violet in colour. It is often associated with spirituality, tranquillity and groundedness, which are believed to protect one from intoxicants. Its distinctive colour and striking appearance make it an ideal choice for a unique gift that will be sure to stand out.


The unique shade of turquoise — the name for the colour derived from the precious stone itself — is the oldest known stone in history. Derived from the French for “Turkish stone”, since it was originally transported from Asia to Europe via Turkey. Bright and bold, turquoise is a symbol of wisdom, protection and nobility and would undoubtedly make a striking impression.


Highly valuable and instantly recognisable, pearl — or mother of pearl — is made from nacre, a rare substance produced by molluscs. Pearls are the origin of the term “pearlescent”, which describes colours that shift and change in the light, creating hues of blue, red, yellow and green on its white surface. Pearls represent calmness, peace and wisdom with their unique properties.
