Gem Lore:
Cameo - is a fashioning process that involves cutting away material, to produce a design raised above the background. The process requires carving a banded material, with two or more differently coloured layers. For clear distinction, the raised figure is in one colour and the background is in another.
Onyx - derives from the greek word ‘onux’, which translates to ‘fingernail’, as the gemstone was thought have a similar appearance, being flesh coloured with white bands. In ancient Greek mythology, the legend goes that Eros, trimmed Venus fingernails, and the gods turned these clippings into stone. The gemstone belongs to the polycrystalline family of Quartz, and was once an umbrella term, used to refer to all the colours of chalcedony. In recent years, the term has been limited, to only apply to brown and black chalcedony. Onyx is a black material, that may or may not possess white banding. Onyx is associated with the astrological symbols of Scorpio, Capricorn and Leo.
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.
Chalcedony, Polycrystalline Quartz:
💎 Hardness: 6 | 💪 Toughness: Excellent | ⚖️ Stability: Good
♥️ Extreme Caution, ⚠️ Avoid: 💡 Light, 🔥❄️ Thermal Shock / Extreme Temperature Change, 🔊 Ultrasonic, 🌪 Steam Cleaners.
💛 Mild Caution, ⚠️ Avoid: 💦 Solvents (💅 Nail Polish Remover), 🧪 Acids / Detergents / Chemicals, ☀️🔥 Heat.
🔬 Gemmological Observation: Quartz is pyroelectric, this means that when the gemstone experiences a change in temperature (for instance heat from the sun/lighting) it causes a low-level electrical attraction to fine dust particles. Therefore, you may experience that any quartz-set jewellery may need frequently cleaning.
Diamond:
💎 Hardness: 10 | 💪 Toughness: Good | ⚖️ Stability: Excellent
💚 Low Caution: A very durable gemstone, generally it is safe to use in; 🫧 Jewellery 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: 🔨 Sharp Knocks. If the diamond is heavily fractured, you will need to ⚠️ avoid using: 🔊 Ultrasonic, 🌪 Steam Cleaners.
