Protect your Jewellery

Be aware of your activity when wearing your jewellery. Remove jewellery before doing household chores, gardening, or sports.  Apply hairspray, lotions, or perfume before you put on your jewellery as chemicals in these items could cause damage.

Cleaning & Storage

Stop by our store every 3-6 months to have your jewellery cleaned and checked to ensure gemstones are safe and secure in the setting. Separate your items from one another by using small bags or compartments in your jewellery box. This keeps your jewellery free from the damage of items rubbing and scratching against each other. Pearls require extra care, as they are organic, sensitive gemstones. You can clean them using mild soap and water, and wipe with a soft cloth after each wear to remove body oils. Avoid getting pearl strands wet, as the silk will stretch and break. However, if they do become wet, dry them on a flat surface and store them away from the rest of your jewellery in a silk or cotton pouch. 

The 4 C’s of Diamonds


Of all the 4Cs, how well a diamond is cut has the greatest effect on a diamond’s beauty. The more precise the diamond is cut, the more light return is possible which leads to a bright and brilliant diamond.

The colour of gem-quality diamonds or ‘lack’ of colour range from colourless to light yellow or light brown. Many of these colour differences are so subtle that only a trained eye can spot them. However, these differences can make a huge difference in quality and price.

Diamonds are the result of carbon exposed to heat and pressure deep inside the earth. They can have natural internal characteristics known as inclusions or external characteristics known as blemishes

Learn more about diamond clarity, and how it is determined:


The carat is the diamond’s weight measured in metric carats. The carat refers to a diamonds weight, and not ‘size.’ If two diamonds have the same carat weight, the cut of the diamond will affect how large a diamond appears.
