Are you in love darling? Well, we have a secret for you. Every love-sick girly who's been thinking about getting engaged with their lifetime partner, or just planning and prepping in advance for when the moment comes with a future partner (ahem, like me) has probably already skimmed through hundreds of wedding ring sites with no clue where the diamonds have been sustainably sourced from. That's why we're here to make your life easier and tell you about the jewelry store every It Girl has been talking about, Frank Darling.

Frank Darling is redefining the jewelry industry with their commitment to sustainability and ethical sourcing. They champion the use of recycled diamonds, recognizing that over 10% of diamonds sold as new are actually recycled. By exclusively using recycled small diamonds in their settings and wedding bands, they embrace the timeless nature of these gems, believing that their sustainable origins make them shine even brighter.

Every ring crafted by Frank Darling is handmade from 100% recycled 18k gold, rejecting the unnecessary environmental impact of mining new precious metals. This dedication ensures the highest quality without compromising on ethics, as they avoid fillers, vermeils, and platings, focusing solely on pure, recycled gold. Which goes to show that luxury and sustainability can go hand in hand, offering ethically sourced, high-quality, and stunning jewelry that aligns with the values of the modern consumer (AKA It Girls). So, if you're ready to create your dream engagement ring or looking for sustainable diamond jewelry that'll last you a lifetime of love and more, keep scrolling for our top picks.
