Diamonds information

Throughout the world diamonds are classified in accordance with the 4C principle (Carat, Cut, Clarity and Colour).

Carat: The carat weight is the weight of the stone. The size of the stones in our articles varies depending on the model.
Cut: All THOMAS SABO diamonds from the Sweet Diamonds Collection are round brilliant cut.
Clarity: Most diamonds have tiny natural features, known as inclusions. Fewer and smaller inclusions permit light to penetrate the stone more easily. The clarity of our diamonds ranges from SI1 to SI2. This means that small inclusions are visible under 10-fold magnification.
International abbreviation International term Definition
IF International flawless No visible flaws
VVS Very very small inclusions Flaws difficult to see

SI Small inclusions Flaws easy to see
P1 1st piqué Flaws difficult to see
P2 2nd piqué Flaws not too difficult to see
P3 3rd piqué Flaws easy to see

Jewellery storage and care tips

  • Store your item of jewellery separately in a fabric pouch or a jewellery case.
  • Items of jewellery should not be worn while working in the house or garden or during sport, bathing or showering or while sleeping.
  • Perfume and hairspray can harm and negatively influence the brilliance of jewellery and the stones. Furthermore, certain substances (i.e. alcohol or other solvents) can impact and damage the surface of pearls and stones.
  • Perfume, hairspray and other cosmetics should be applied before putting on your jewellery.
  • Clean your diamond jewellery once a month to prevent deposits of grease, soap and cosmetics.
  • Use a special detergent or a small amount of mild neutral cleaner added to a bowl of warm water. For the best cleaning results, gently use a small brush or a paintbrush. Also treat the back of the jewellery (including the setting).
  • You can also use an ultrasound device if you have one (please note the instructions for your ultrasound device).
  • To clean our items of jewellery (also two-tone items of jewellery), you can use standard commercial silver dipping baths or silver cleaning cloths. No silver cutlery dipping baths and no gold jewellery dipping baths must be used. Immerse the jewellery for a maximum of 5 minutes. Then thoroughly rinse the jewellery with warm water and rub it dry with a cloth. Blow dry it if possible.
