Shine On Crazy Diamond - tips to keep your diamonds clean

Diamonds are the hardest known natural substance known to man. They can cut through any metal or rock and the only way to cut diamond is with another diamond (with the exception of lasers). They are such a popular choice for jewellery as they sparkle more than any other gemstone and due to their exceptional hardness and good durability they make the perfect choice for engagement and wedding rings. Due to their top position on the Mohs scale, 10, they can take a very good polish and they are assigned the highest lustre named “adamantine”, after the Ancient Greek word  adamas, which means firm, rigid or unyielding.

Diamond has an interesting property named hydrophobia.

Being made of carbon, diamond may be compared to the organic compounds (diamond is elemental carbon) and it has one property where it is described as being HYDROPHOBIC (a property also possessed by fats, oils, greases and waxes - all organic compounds) where droplets of water “bead up” on the surface of a diamond because diamond has no affinity for water and the surface of a diamond cannot be “wet” by water. This is an important point because the hydrophobic nature of diamond means that this allows fats, oils, greases and waxes to adhere to the surface of the diamond reducing the brilliance and fire of the diamond. Anything from sunscreens, moisturizers, make-up and oils and fats used in cooking and food preparation can reduce the sparkle, fire and brilliance of diamonds. Even the natural oils and grease from your fingers will adhere to your diamonds thus making regular cleaning inevitable.

It’s recommended that one doesn’t wear diamond jewellery while preparing food, gardening, performing heavy exercise and showering – oils from hair products and body washes can stick to diamonds and dull their lustre. Fats and oils won’t harm your stone, however they will affect your diamond’s performance.

Due to diamonds’ hydrophobic nature it’s necessary to give them a regular clean. This can be done at home with a few simple tools. A simple plan to keep your diamonds sparkling is to soak them once a week in a gentle degreasing solution such as warm water with a few drops of mild dish soap or cloudy ammonia. Another home cleaning tip is to leave your diamonds soaking overnight in an ammonia based cleaning product such as a window cleaner. After the soaking, gently brush with a soft toothbrush that is used exclusively for this purpose. Be sure to get underneath the settings and clean the pavilion facets where oils and dirt can be trapped. Gently rinse in warm water then leave to dry on some clean paper towelling. A hair dryer is a great way to quickly dry jewellery without getting fibres from towels trapped under claw settings.

There are a few precautions to keep in mind:

Be careful cleaning jewellery near sinks and open drains. Make sure plugs are securely fitted before rinsing or rinse in a bowl away from drains. Use a rubber sink mat where possible to avoid breakages or knocks to settings if the jewellery is accidentally dropped.

Do not use harsh chlorine based cleaning products (such as household bleach) or abrasives (such as toothpaste) to clean diamond jewellery. These types of harsh cleaners can erode or even dissolve metal resulting in damaged settings or loosened claws. (NB: Do not wear precious metal jewellery in swimming pools or spas as chlorine erodes metal).

Check to see if your diamond is still secure in its setting. Shake it close to your ear and if you suspect you hear the diamond rattling, take it immediately to your jeweller for inspection.

There are also good commercial cleaning solutions available to clean diamond jewellery at home. Your local jeweller may sell it or you can visit a jewellery supply store. Normally it’s a solution in a round pot that contains a plastic basket. The jewels are dropped into the basket then lowered into the solution and left to soak for 30 seconds or more depending upon the product. Once the diamonds have soaked, retrieve them and gently clean with a soft brush. Finally rinse them in warm water then dry with a hair dryer. Be careful to read any instructions and only use these solutions for diamonds and perhaps ruby and sapphire. Other gemstones, especially pearls, turquoise and opals can be damaged by these solutions.

If you’re passing by your jeweller ask for an ultrasonic quick clean. This is normally a free service or a small charge may be incurred for jewellery purchased from other stores. It’s also recommended that you get your diamond jewellery cleaned professionally once every 18 months to two years. You’ll be delighted to see it all looking brand new again and this is the perfect opportunity to have a jeweller check all your settings and rhodium plate any white gold that may have lost its coating.

There are two main types of opal – precious and common. Precious opal displays iridescence, or play of colour, due to the diffraction of light off the tiny, closely packed silica spheres in the atomic lattice of the gem. Common opal does not possess iridescence due to its silica spheres being random in shape, size and arrangement.

Parti sapphires

Parti sapphire is part of the most important gem family, corundum, which also includes ruby. Sapphires have consistently risen in value and popularity, due to their beauty, durability and versatility. The rarity of parti sapphires makes them valuable, especially bigger stones, and stones with brighter colours. Compared to blue sapphire though, parti sapphire is exceptionally good value. Parti sapphire engagement rings have been rising in popularity due to the gem's exceptional beauty and individuality.

Ring sizes

We use Australian ring size measurements, which are in an alphabetical range from A-Z.

As your fingers contract and expand due to the temperature, humidity, exercise, etc, your ring will fit on your finger tighter or looser. Your ring should fit comfortably and you need to find a balance between too big and too small. It is recommended that you should have to push your ring on tightly over your knuckle and it should spin slightly around the base of your finger. There should be some resistance when the ring is taken off – this will help to keep the ring on when your fingers are cold or wet. The correct size is the one that you feel the most confident and comfortable with.

We suggest that you size the finger you intend to wear your ring on at room temperature – this should provide you with a size that should be close to perfect most of the time.

Top-heavy rings can tend to spin on your finger, as the base of your finger is usually thinner than your knuckle. We suggest when sizing your finger for a top-heavy ring, that you err on the tighter side, rather than a loose fit. This will mean that the ring will stay on the top of your finger and it will ultimately be more comfortable to wear.

If you’re choosing a wide ring, you will tend to go up a size. There is more surface area on a wider ring and therefore more metal to grip to your finger.

If you are interested in a ring that is 5mm or wider, we suggest going up a size (one size larger than the sizing gauge). We suggest going up another size if the ring you are interested in is 9mm or larger (two sizes larger than the sizing gauge).

If you are buying a ring as a gift for someone, we recommend that you measure the inside diameter of a ring the person you’re buying the gift for, regularly wears on the finger your gift will be worn on.

Measuring your finger

If you do not know your ring size you can use this guide to obtain an approximate measurement.

Before measuring the finger on which the ring you’re purchasing will be worn, please ensure the following:

The number that lines up with edges of the opening is the ‘interior circumference’. Please note this number and then refer to our Ring Size Chart to choose the correct ring size.

If you do not know your ring size you can use this guide to obtain an approximate measurement.

If you have a ring that is worn on the finger you need sizing, print out the ring size guide (take care to print it at 100%), and place the existing ring over the circles. Measure the inside of the ring against the outside of the circle. If you can hardly see the black line which goes around each circle, you have chosen the right size. Compare the ring to the adjacent circles to check that you definitely have the right size.

You can then double check this measurement by measuring the inside diameter of the ring, and matching that against the ring diameter measurements shown.

Alternatively, if you don’t have a ring available, you can measure the finger itself to obtain an approximate ring size. You can do so by wrapping a piece of string or thin strip of paper around the finger on which you wish to wear the ring, marking it with a pen where it overlaps. Measure the piece of string with a ruler to obtain the circumference of the finger, and compare that to the European Size measurement shown on the chart. We would recommend that in order to obtain the most accurate measurement when taking your ring size in this way, you do so at the end of the day when the finger is at its largest, and not when your hands are unusually cold as this would lead to a smaller ring size.
