The easiest way to choose jewellery is to start with your undertone. Look at the veins on your wrist in daylight: greenish veins usually mean warm undertones, bluish ones mean cool, and a mix of both means neutral.
Warm skin tones glow in yellow gold, copper and bronze, and in stones such as amber, coral and citrine. Cool skin tones are flattered by silver, white gold and platinum, paired with sapphires, amethysts or pearls.
Neutral undertones can wear almost anything, so let the outfit decide. When in doubt, hold two pieces against your face in natural light; the one that makes your skin look brighter is the right one.
