All Cris Maria Jewelry pieces are made in Portugal, mostly by hand, in 925 silver, using traditional jewelry techniques.

Pieces in 9, 14 or 18 carat gold can be made to order.

The gold-plated silver pieces are plated with 24-carat gold, 1 or 2 microns thick.

The gems used can be synthetic or natural.

Cris Maria Jewelry pieces are certified by the Contrastaria da INCM - imprensa nacional - casa da moeda, S.A.

The assay office checks the legal touch, i.e. determining the amount of precious metal (in permilage) contained in an alloy (silver or gold) and applies the contrast (seal guaranteeing compliance with that check), next to the responsibility mark of the producer of the piece.

Contrasting is only compulsory for silver pieces weighing more than 2 grams and gold pieces weighing more than 0.5 grams.

If the buyer is in any doubt as to the authenticity of the marks, he can use the assay office to check.
