At Andrew R Ullmann we use our knowledge and experience to date each individual item based on materials, construction, hallmarks and overall style. We determine the age and authenticity of our jewellery to the best of our ability based on our knowledge, experience and resources. However, as the Hallmarking Act only came into force in 1973 we often have to estimate the age of a piece where an exact age cannot be verified.

Where a piece is constructed in a way that makes it difficult to determine a precise stone’s grading we use our knowledge to estimate colour, clarity and size to our best ability. Diamonds and coloured gemstones that cannot be removed from their vintage settings without harm to the piece are examined in their mountings using industry-standard measurements and formulas. Unless certified by an independent laboratory, stone gradings are done by us. All diamonds shown on our website are natural, untreated diamonds. Sometimes coloured gemstones (i.e. rubies, sapphires and emeralds) may have undergone some degree of heat treatment or oiling which may not be possible for us to detect.

We are not liable for any inaccuracies or errors which are beyond our reasonable control. In particular, we cannot guarantee that colours in our images will be rendered correctly on different computer monitors. The product dimensions supplied are intended to give an approximate indication of the size of individual products. Products shown may not be actual size. If you have any doubts about the colour, size or any other specification of the goods you wish to order, we recommend you Contact Us prior to placing an order on the Website.
