Why Sapphires Make the Best Diamond Alternative for Engagement Rings

Nov 29, 2025

Diamonds are a girl’s best friend, but sapphires are hard to resist. Modern couples are redefining their relationships in different ways, and we love to see couples put their own unique twist on our favorite Valley Rose engagement rings. If you’re looking for a diamond alternative, sapphires are one of the best options. Synonymous with royalty, sapphires have been seen throughout history as a protective talisman and a unique symbol of love.

At Valley Rose, our responsibly sourced sapphires are the perfect option if you want a sustainable engagement ring and aren’t feeling drawn to a lab diamond. Our sapphires come from small-scale artisanal mines and are fully traceable with low environmental impact.

Why Sapphires Are the Ultimate Diamond Alternative

A sapphire engagement ring is the perfect choice for a couple who have their anniversary or a birthday in September, as it’s the birthstone associated with that month. They’re one of the most popular diamond alternatives as they rate in at a 9 on the Mohs scale, making them one of the hardest gemstones – second only to diamonds – and ideal for wearing every day. 

What we love about sapphire engagement rings is that every stone is a little different. Our collection of Australian and Montana sapphires is available in a range of colors, including teal, blue, and green. Sapphires have their own personality and can add a pop of color and extra meaning to your engagement ring.

Sustainability and the Ethics of Sapphire Sourcing

At Valley Rose, we strive to create high-quality, ethical jewelry that honors the earth by ensuring people in our supply chain are paid fair, livable wages and there is minimal environmental impact with the extraction of our materials and supplies. 

Although there are currently no third-party certification systems available for sapphires, we guarantee that our Australian and Montana sapphires are bought directly from our partners, making them a low-impact option for couples searching for a sustainable engagement ring.

Our sapphire engagement rings are also made using fairmined gold, a better alternative to recycled gold, as it is sourced from responsible artisanal and Small-Scale Mining (ASM) with rigorous 3rd-party certification and audit systems. These sustainable materials allow us to create beautiful engagement rings that are kind to people and the planet.
