All Kristina Ferenchuk pieces are handmade from 18 karat Gold or Sterling Silver 925, precious and semi-precious stones and are meant to be treasured, worn everyday and become future heirlooms.

To ensure the longevity of your jewellery, we recommend:

- Treat with care and avoid straineous activities, which will expose your jewellery to knocks and scratches.
Remove your jewellery before bed, showering and washing your hands.

- Avoid exposing your jewellery to perfume, hair products and cosmetics.

- Store your pieces separately to avoid scratching.

- Metals can naturally develop a surface patina over time from oxygen, sprays, creams and skin acidity.

- Avoid using bleach, hand sanitiser and chemicals with opal stones and pearls.

Jewellery can become tarnished from daily wear and polutions in the air. In order to restore luster and shine we recommend:

- Polishing gold pieces with a dry and clean polishing cloth

- Diamond pieces are to be cleaned using a soft bristle brush and warm soapy water, followed by a rinse in warm water and dried with a soft cloth.
