Couples who want to share more than vows are getting the opportunity to share their bone too in a "bio jewellery" research project.

Five couples are having the rings made. They will be grown from bone cells taken from their jawbone.

I doubt my husband would go for such a thing. However, he has given me permission to turn his ashes into diamonds.
