Treated Blue Diamonds

Treated Blue Diamond Wedding Bands & Engagement Rings

For a unique ring that maintains its class and sophistication, it’s hard to look past the stunning appeal of blue diamonds. It is extremely rare to encounter naturally occurring blue diamonds. Australia’s Argyle mine, located in the East Kimberley region, is responsible for most of the world’s supply – but unfortunately, these natural gems have a price tag that reflects their rarity.

Our treated blue diamond engagement rings offer a more affordable alternative that matches the naturally occurring fancy stones for vibrancy, beauty and richness of colour. Set in beautiful 18ct white gold, our rings combine the timeless appeal of diamonds with a distinctive burst of colour. They’re also available in a range of elegant designs, ranging from the bold and the modern to some more traditional looks.

MDT Design specialise in unique, handmade engagement rings and decorative wedding bands. View previews of our blue diamond wedding bands and engagement rings above or reach out to our team to discuss custom designs.
