Gem Lore:
Yellow Sapphires - mainly when people hear the word Sapphire, they immediately think of the colour blue. However, some maybe surprised to know that Sapphire, can come in an array of hues: orange, yellow, white, green, pink and purple. Yellow sapphires possess subtle overtones, from vibrant greenish yellow to a subdued peachy orange and vivid reddish browns glints. Yellow sapphires symbolise wisdom and prosperity.
Diamond - derives from the Greek word ‘adamas’, which translates to ‘invincible’. Today, the meaning somewhat refers, to the gemstones excellent hardness (ranking 10 on Mohs' scale), hence diamonds are highly resistant to be scratched or abraded by another material, other than diamonds itself. Moreover, diamonds possess the magical phenomenon of fire, which relies on the facetted gemstones ability to disperse (split) light, into a rainbow of colours.
The ancient Egyptians thought diamonds symbolised life, and the Pharaohs were known to place the gemstone in the centre of an ankh cross. Whereas, the ancient Greeks believed diamonds to be the tears of the gods or broken splinters from fallen stars. Alternatively, in ancient Roman literature it is noted that Cupids arrows were ‘diamond tipped’, maybe one of the first references that associates the gemstone with love.
Jewellery Care Precautions:
Avoid direct contact with: perfume, lotions, skincare, hairspray / other chemicals. Remove, your jewellery: when showering, swimming (as both chlorine and saltwater will react with metals), washing your hands / using hand sanitisers, before going to bed or when participating in physical activities (going to the gym, exercising, gardening, housework etc….).
Beware, metals may tarnish over time due to oxygen contact and natural body oils. Prevent items from being exposed to moisture and direct sunlight, for long periods. Store jewellery in a dry place away from humidity, in a pouch/jewellery box and keep each piece separated from each other. Care, for your jewellery by cleaning with a soft dry cloth.
Yellow Gold:
Gold as an element, in its purest form will not tarnish, but gold used in jewellery has been alloyed with other metals, to increase durability. These metals have properties that when in contact with oxygen, chemicals, oils or other substances - will result in a surface tarnish or damage and corrosion. Even the pH level of you skin and the natural oils it produces, can tarnish your gold jewellery.
To prevent your gold jewellery from tarnishing or even disintegrating, avoid exposure to household chemicals, bleaches, toothpaste, baking soda and other cleaning abrasives. Wearing jewellery in places where perfumes, hairsprays, body lotions have been applied on your body, will increase tarnishing. Wear your jewellery after the products have been applied. To clean your gold jewellery, use a mild soap with warm water and dry with a soft cloth. For professional cleaning, our workshop can polish your jewellery back to life.
White Gold:
White gold is not an element and does not occur naturally in a pure form. Pure yellow gold is mixed with alloys of white metals (such as palladium) to produce, a silver coloured alloy, known as white gold. It is further coated in a precious metal called rhodium (an element that derives from the same metal family as platinum), to increase its lustrous sheen and protect it from tarnishing and scratching.
Over time with exposure to oxygen and moisture, the rhodium coating will naturally wear and you will begin to see the natural yellow colour of gold. Rings will experience this more than other types of jewellery. The general guide for re-applying rhodium coating to your rings is between 1-2 years. However, the rate of wear depends on the pH level of your skin, exposure and contact to chemicals. For professional cleaning and rhodium coating, our workshop will provide the TLC your jewellery needs.
Fancy Sapphire, Corundum:
Hardness: 9 | Toughness: Excellent | Stability: Very Good
Low Caution: A very durable gemstone, generally it is safe to use in; Jewellery Cleaners (Dips, Ultrasonic, Steam Cleaners).
Gemmological Observation: Corundums are a very durable gemstone. However, if lead-glass filled or heavily fractured, you will need to avoid: Chemicals (acids, detergents), Direct Heat, Jewellery Cleaners (ultrasonic, steam cleaners).
Diamond:
Hardness: 10 | Toughness: Good | Stability: Excellent
Low Caution: A very durable gemstone, generally it is safe to use in; Jewellery Cleaners (Dips, Ultrasonic, Steam Cleaners).
Gemmological Observation: Diamonds have excellent hardness, this means only a diamond can scratch/abrade another diamond. To avoid scratches, store your diamond set jewellery separately. Diamonds only have good toughness, as they possess perfect cleavage. This means that if knocked in the wrong direction, the diamond can cleave/fracture. Whilst wearing, you will need to avoid: Sudden Impact (sharp knocks). If the diamond is heavily fractured, you will need to avoid using: Jewellery Cleaners (ultrasonic, steam cleaners).
