A bog oak brooch made for you by Trish Rogers Originals. Authenticated by Queens University Belfast (QUB) as being 6,000 years old, the bog oak used by Trish means customers can wear or display a little piece of Irish history. An extremely hard wood, bog oak has a lustrous jet-black shade after being polished into its final form, with growth lines visible in some pieces, giving added character and depth to the products. Gathering the wood herself from the bog near her home, Trish carefully selects the pieces she thinks are best suited for sculpture or for jewellery. Often, these are large chunks of trees brought up from deep within the ground, which are many thousands of years old.
