Care Guide

Understanding how to care for your precious ADC engagement ring and jewellery makes a world of difference in maintaining their optimum condition. We understand jewellery lives with you through a range of activities and conditions. To preserve the brilliance and longevity of your ADC pieces, we recommend the following:

All ADC pieces are entitled to complimentary professional cleaning for the lifetime of the piece. Regular cleaning is advised to highlight the brilliance of your diamonds and jewellery. By cleaning your pieces regularly, their condition is preserved as the accumulation of grime around settings and metal can be relieved in the cleaning process. In cases where stone settings present a strong build-up of grime, this can result in damage to setting as the dirt competes for space within the setting resulting in stone loss.
Your ADC jewellery is designed to be worn and enjoyed. The rigours of everyday life can place strain on settings and other areas of your jewellery. Inspections play an important part in the overall maintenance of your jewellery and can often avoid costly incidents such as stones falling out of your piece. During an inspection, ADC diamond specialists conduct thorough assessments with specialised tools to ensure all stones are securely set and in optimum condition. As this service is complimentary with every ADC purchase, we welcome you to visit our showroom for an inspection at least every 6 – 12 months.
Our comprehensive warranty provides peace of mind and confidence with every ADC purchase. Every ADC piece has been meticulously crafted to the highest quality standards, which is why we offer a lifetime warranty against manufacturing faults or defects. ADC applies its lifetime warranty on pieces that are regularly maintained from the date of purchase. Regular maintenance requires cleaning and inspection of ADC pieces at least once every 12 months.
Diamonds are one of the strongest materials known to man. This fact leads to the assumption diamonds are indestructible. The truth is, with enough force, the structure of a diamond can be impacted, resulting in fractures or chips. By protecting your diamonds from heavy impact, you will preserve the condition of your diamonds. Should your diamonds sustain impact damage, you should consult an ADC diamond specialist for advice.
Coloured gem stones (such as amethyst, kunzite, topaz, morganite, aquamarine.) can darken or change colour over time when exposed to high levels of light. The sun’s harmful rays can affect a coloured gemstone’s durability and colour. Coloured gemstones are appreciated for their unique character, making them the ideal choice for jewellery. Coloured gemstones occur in a range of colours and are comprised of various materials that determine their structural integrity. Being so, coloured gems are ranked on the Mohs scale accordingly. Compared with diamonds, coloured gem stones are typically softer and more brittle and therefore should be protected from impact that can result in damage. It’s important to note that coloured gemstones should not be submerged in ultra-sonic cleaning machines as the vibrations may harm the stone. ADC pieces containing coloured stones may be cleaned in warm water and soap with a soft brush. Below is the Mohs Scale of Hardness that indicates the hardness of gem-stones likely to be found in jewellery:
10Diamond
9Ruby, Sapphire
8.5Chrysobel, Alexandrite
8Topaz, Spinel
7.5Morganite, Emerald, Tourmaline, Zircon, Andalusite, Beryl
7Iolite, Chrysoprase, Citrine, Jade, Onyx, Kunzite, Quartz, Blue Chalcedony, Amethyst, Ametrine, Garnet
6.5Garnet, Jade, Tanzanite, Peridot
6Moonstone, Sunstone, Labradorite
5.5Lapis Lazuli
It’s important to note that there is no such thing as natural white gold; all gold appears yellow when mined. To create white gold for jewellery purposes, raw gold is combined with alloys to give it colour and strength. To achieve a bright white and consistent finish, a fine layer of liquid gold is applied using a process called electro rhodium plating. Over time, with enough exposure to external elements (such as lotions, perfumes, chemicals, alcohol rub, dead skin cells, dirt, and rough surfaces) rhodium plating will wear to expose the base colour of gold. This colour can have a yellowish appearance. The rhodium plating on your ADC white gold pieces can be re-applied to restore its original condition. The time that lapses between rhodium plating depends on how the piece is worn. Pieces that frequently encounter the aforementioned elements will require rhodium plating more frequently than those with less exposure to these elements. To prolong the life of your rhodium plating, you may choose to remove your pieces to avoid contact with harmful elements. Caring for white gold requires regular cleaning, inspections and polishing to keep pieces in optimum condition. Should you wish to have your ADC pieces rhodium plated, you may schedule a maintenance appointment to discuss the cost and timeframe of the services specific to your white gold pieces.
Platinum is a hard metal, making it the ideal choice for precious jewellery. Platinum used in ADC jewellery is comprised of 95% platinum and 5% alloys. Unlike 18ct white gold, Platinum is naturally white in appearance so it does not require rhodium plating to achieve its finish. This means caring for platinum requires regular cleaning, inspections and polishing. Impact damage sustained to platinum should be assessed by an ADC jeweller to ensure the optimum condition and security of stone settings.
ADC jewellery can be cleaned in the comfort and convenience of our showroom as a complimentary service valid for the lifetime of your piece. To maintain your pieces in between visits to the showroom, you may choose to clean your ADC pieces by submerging them into a solution of warm water and detergent-free dish soap. Taking a soft toothbrush to intricate setting areas and precious stones will relieve dirt build up from your jewellery, keeping stones and settings safe. If you notice your pieces are showing signs of wear, please visit the ADC showroom to have them inspected and cleaned as a complimentary service and to discuss the maintenance services available to you. It is vital to avoid impact damage to your ADC pieces to prevent scratches, dents, loss of stones and chips to precious stones. By removing jewellery prior to performing manual tasks (household duties, gardening, high contact sports, activities at the gym, manual labour), the risk of your pieces sustaining impact damage is minimised.
If you have multiple precious pieces, it is recommended to store them in a jewellery box designed specially to hold multiple pieces. It is important to store chains and necklaces flat and separate from one another to avoid knots and tangling. Precious stones should be stored upright and away from other stones and metals to avoid impact damage.
