Introducing the first ever carbon negative piece of jewellery. We have partnered with Go Carbon Neutral to more than offset the carbon emissions generated during the creation of the Crann Carbon Negative Signet Ring. For each purchase of the ring, we will plant a native deciduous tree in Ireland. Unlike many other tree planting initiatives, our trees will never be cut down. This enables a rich habitat to evolve and becomes a permanent carbon off-setter. Once you purchase, we will share information on exactly where in Ireland your tree will be planted.

The Crann Carbon Signet Negative ring is a large signet ring weighing a heavy seven grams. It is cast in eco-friendly recycled silver and is hand finished by our expert jewellers in Dublin City Centre, making each piece completely unique. The eye catching tree symbol design is hand engraved on the large circle face and the shoulders and band are carefully polished with a mirror finish to stand out and catch eyes. Like all Dána Project pieces, the Crann Carbon Negative Signet Ring is designed to be life lasting. It is heavy enough to withstand everyday wear and tear, which also gives you the feeling of luxury when worn on your finger.


A finger can swell and contract depending on the time of day, the weather or the food you've eaten. Figuring out the correct ring size is no easy task. To make things easier we offer a free ring sizer to make sure you get the perfect fit. 

Don't worry if you're not 100% confident on your ring size, we are happy to exchange rings for smaller or larger sizes at your request. 

To determine your ring size:

Use a piece of string and wrap it around the base of your fingerMark the point on the string where the end meetsUse a mm ruler to measure the length of the stringMap the mm length of the string to the chart below to find your Dána Project ring size

You should allow enough room for your knuckle and remember that different fingers on the same and opposite hand may have different sizes. Measure the specific finger on which you plan to wear your Dána Project ring. It is best to measure your finger at the end of the day when it is likely to be largest.

Please note, we cannot offer exchange or return of jewellery pieces that have been customised with initials.

Check out our size guide page for more information.
