What is Moissanite?

In the most simple of definitions, moissanite is a natural, lab-created stone alternative to a diamond. Moissanite and diamonds look similar and rank similarly in durability, but their carbon footprint and price are the biggest differences. Without the environmental or humanitarian costs of mining, moissanite takes the stage as a solid ethical sparkle. It is grown in professional labs with earth-like heat and pressure and takes up to 3 months to form a single gemstone. Beyond the science, moissanite shines as the clear winner for couples looking for the most socially- and eco-responsible engagement ring option.

These stones also come in a rainbow of colors, so whatever your preference is, you have options such as gray, white/clear, pink, teal, and more. (Or maybe one of each if that’s your fancy?!)

What are the differences between moissanite and diamonds?

Though carbon footprint and price are the most welcomed differences, there are a few other minor differences between moissanite and diamond to know when selecting your engagement rings.

As you might have learned in geology class, the diamond is the hardest known mineral in the world and is a 10 on the Mohs Scale of Hardness (aka good luck trying to break that!). Moissanite comes in at a 9.25-9.5 on that same scale making it the second hardest mineral out there. So scratching the surface of your ring would be a difficult feat to accomplish. It’s 100% perfect for wearing everyday!

How much does moissanite cost?

Because of the sustainability of moissanite, these gemstones are significantly less expensive than diamonds. If you love a larger stone size or more intricate ring design, you can definitely get more for your money with moissanite. Same look, different price! Instead of the diamond’s costly sourcing tariffs taking over a good chunk of the entire ring’s value, you’ll be paying for the remarkable craftsmanship and the ethically-made gem with moissanite engagement rings. You can find high quality rings priced at every budget, so moissanite really is a stone accessible to every couple.

Why is moissanite perfect for engagement rings?

Practically speaking, because of its durability, you can wear moissanite all day, every day! And for the eco-minded person who is aware of the jewelry industry’s dark history of pollution and exploitation, there really is no question as to why they prefer moissanite to celebrate their life-long commitment to their partner.

That's why we love Kristin Coffin's moissanite engagement rings. Not only are the gems ethically-sourced, she has designed her collection and business around using recycled precious metals and by creating meaningful heirlooms that resonate with the values of this modern generation.

Where is moissanite sourced?

Moissanite stones are sourced from certifiable professional labs all around the world, so the diversity of locations is large! But for Kristin Coffin specifically, moissanites are sourced from USA-based Charles & Colvard, or her own line of Iconic Moissanite, where she has her own team of moissanite gem cutters in Europe. Kristin and her team of highly skilled goldsmiths create these moissanite ring beauties in recycled golds and platinum here in the United States, striving to keep the carbon footprint of each ring as light as possible. When we say everything eco has been thought of with our friends’ heirloom, it really has, so you can feel 100% good about your engagement ring.

How to Store and Clean Moissanite Engagement Rings

Like any precious jewelry, you’ll want to make sure to look after your moissanite engagement ring for its lifetime on your hand. Kristin Coffin recommends, "Remove your ring during activities like weightlifting, gardening, biking, showering, swimming, household chores, or while working with your hands. Avoid wearing your rings while handling household solutions like hairspray, perfumes, makeup, household cleaners, or while using abrasives."

Beyond a professional cleaning once a year, you can also clean your engagement ring by soaking it in warm water with a few drops of oil-free dish soap. Gently scrub with a soft-bristled toothbrush and allow to air dry.

To store while not wearing (or even to propose with!), we recommend keeping your beautiful heirloom in a wedding ring box tucked away from dust or curious paws and claws.
