Which material?
Yellow gold ? White gold ? Rose gold ? Platinum ?
Skin tone
On a physical basis, yellow gold is considered a rather universal colour that looks nice on almost all skin tone but its especially pretty if contrasted with olive & darker skin tones.
Meanwhile for fair skin people, white gold carries a timeless elegant aura to the wearer and complement beautifully to fair & rosy skin tones.
Rose or pink gold, which has the pinkish hue derived from the copper alloy, is beautiful on both fair and olive skin tones. It is the ideal choice for people who are looking for different, unique and more romantic option for wedding or engagement rings. In fact, it is also especially appealing to people who are looking to add that subtle vintage element to their rings. Rose color stands out beautifully against pale skin but it might not look as lovely as yellow gold does against darker skin tones. It is also a perfect fit for individuals who has seasonal change of skin tone.
Karat
For first time jewellery buyer, it is important to take note that most gold jewelleries that you see either at retail or sold online are in 14K or 18K. Reason being these type of gold is more durable and can be shaped into different designs easily as compared to high-karat yellow gold, which can be easily scratched and dented. In other words, the higher the Karat, the 'softer' it gets. it requires much frequent maintenance like cleaning & polishing to be done.
Platinum is a dense material. The sole reason certain individuals prefer platinum is because of it's unchangeable silver colour nature that gives it the lasting tone over the years. Its price, however, costs about twice as much as 18K. Also, there are rather few suppliers in the market who offer this material making it even rarer, time consuming and costly for repair or molding. Meanwhile, although 18K gold requires polishing every few months, the cost is relatively low and most ladies treat it as habitual as it is going to a hair salon for a haircut.
