We’ve spent years researching and wearing ethically sourced diamond rings. These are our picks for brands with lab-grown diamond rings. For those who are ethically and sustainably conscious, buying fine diamond engagement rings can be tough — especially when you’re not sure where or how it’s sourced. One way to guarantee the traceability of your diamonds is to buy lab grown instead of naturally sourced. Whether you’re looking to buy something for yourself or a loved one, these lab grown diamonds are an ethical and sustainable choice without compromising on design for the ring you’ve been dreaming of. 💍
