Our Blythe Engagement Ring Set with a Pear-Cut Montana Sapphire

Colored Gemstone Center Stones

Choosing a colored gemstone as your center stone gives your engagement ring a fresh, meaningful, and distinctive feel. We most often work with sapphires, which come in an incredible range of hues like deep navy, pale blue, mossy green, lavender, peach, and white. Known for their durability, sapphires are ideal for daily wear and are a favorite among couples seeking a non-diamond center. You can browse our stunning collection of Misfit Sapphires to find your perfect center stone!

We also offer lab-grown colored diamonds (as well as ethically mined) in timeless shades like pink, yellow, and blue. These stones combine lasting durability with ethical sourcing and stunning color. For a more classic look with a bold twist, we also offer select emerald and ruby center stones.

At our Boston jewelry studio or through an online consultation, we’ll walk you through each stone’s meaning, durability, and color options to help you choose the perfect match for your design and lifestyle. 

Our Blythe Engagement Ring with Ruby Side Stones

Gemstone Side Stones

Want to add a hint of color without changing your center stone? Colored gemstone side stones are a beautiful way to personalize your ring while keeping the overall look classic. Whether you want to include a birthstone, mark a meaningful date, or add contrast, gemstone accents offer endless creative possibilities.

We most often work with sapphire side stones and lab-grown colored diamonds for this customization. Both are highly durable and ethically sourced, and available in rich colors like blue, green, peach, pink, white, and yellow. These stones are perfect for those who want to subtly weave in their personal story while maintaining timeless style. Some of our favorite styles to pair with colored side stones are Blythe and Portia!

Ethically Sourced, Carefully Selected

Every gemstone we use, whether natural or lab-grown, is ethically sourced and conflict-free. As a responsible Boston-based jeweler, we work only with trusted suppliers who meet our environmental and ethical standards. Whether you choose a sapphire, ruby, emerald, or colored diamond, you can feel confident knowing your ring was crafted with integrity.
