Mazzucchelli’s · Since 1903

Our most striking diamond jewellery

The pieces in this collection carry more than five carats of diamonds in total weight, set along tennis bracelets and diamond necklaces that catch the light with every movement.

Lab grown and natural diamonds

Many of these pieces use lab grown diamonds, which have the same brilliance as natural diamonds and make larger carat weights more attainable. You will also find pieces with Australian natural champagne diamonds. Check each product page for the diamond type and weight.

Made to be treasured

A piece like this is a considered purchase, so we are here to help. Visit a store or book time with our diamond experts, or explore more tennis styles.
