We run specials every month where we offer beautiful jewellery at unbeatable prices. Should you not have a JDC store nearby, you can visit another jeweller and ask them to measure your finger size. Finger size changes depending on the time of day and the weather. For the best accuracy, measure your finger when your hands are warm as well as when they are cold. (Fingers are generally smaller in the morning and larger in the afternoon.) You can also borrow one of your significant other’s rings that she wears on her ring finger and take it to your closest jeweller and ask them to measure the ring for you. If you are in the possession of a vernier you can measure the inside diamater of the ring and use the chart below to find the finger size. Should you measure and a finger size comes in at the bottom of this chart, but your significant other has dainty hands, or vice versa. Wrap the paper around the finger of the person that you wish to purchase the ring for (as tightly as possible.) Make sure the paper is below the joint of the finger and close to your knuckle. Start by lining up the start of the paper with 0 on the ruler. Keeping the piece of paper straight the mark will line up with another number on the ruler. Use this measurement and the circumference on the chart below to determine the finger size that you need. For example, some jewellery pieces are especially vulnerable to household chemicals and extremely high temperatures. We recommend you use Connoisseurs jewellery cleaner available for purchase through our online store. You will also need a very soft toothbrush if there is no brush included with your jewellery cleaner. After cleaning your jewellery items, rinse thoroughly with luke warm water and then dry it with a soft cloth. To ensure that your jewellery keeps its brand new sparkling look for as long as possible, we recommend that you store it separately, as gemstones have a higher density than precious metals and will scratch your jewellery if kept together. While it’s true that gemstones such as ruby and sapphire are second only to diamond on the hardness scale, it is not a measurement of their indestructibility. It means that these gemstones are able to resist scratching almost as well as a diamond. Abrasive surfaces, harsh chemicals, and sharp blows can damage even the hardest gem. Your jewellery should be the last thing you put on when getting dressed and the first thing you take off at the end of the night. Store your jewellery carefully and it will be enjoyed for generations.
