Selecting the perfect gift for your loved one at Christmas time can be a little daunting but it doesn't have to be. My advice is to keep the following three things in mind: her personal style, her lifestyle, and her current jewellery collection.
Choose something that reflects her personal style, which could be modern, classic, colourful, amongst others. Choose something that you know she will get a decent amount of wear from. Either for special occasions, or for every day.
And lastly, it's a great idea to go for a piece that can be mixed into her current fine jewellery collection. Consider going for something in the same colour metal as her favourite pieces or with similar diamond and gemstone shapes, or setting styles.
