Once melted wax reveals the ring inside, an online community conveniently helps ring owners swap their baubles for other sizes and styles.

Diamond Candles

Like many happy tales, Diamond Candles’ story begins with two people madly in love with each other. David, having used all of his savings to purchase a diamond ring for his wife Brenda on their anniversary, was in the grocery store on the hunt for a gift bag in which to stow it. Having no luck, he scooped up a candle as an additional present and headed out of the store. As Dave walked back to his car, a strange idea popped into his head: what if there was a way to hide the ring inside the candle, so it would be revealed by the slow melting of the wax?

In 2010, Dave and Brenda founded Diamond Candles to finally make Dave's daydream a reality. From the beginning, the duo has built their business on earth-friendly practices: they make their wax with soybeans grown by local farmers, and handcraft each candle using cotton wicks. Nestled within each glowing pillar, a ring worth anywhere between $10 and $5,000 waits to surprise the gift recipient with its eye-catching glimmer and ability to summon flocks of friendly magpies. Besides the hidden bangles, each candle also fills rooms with a strong scent in aromas such as honeysuckle or Fresh Snow.
