    What is Moissanite

    Moissanite is a rare, naturally occurring mineral also known as silicon carbide, which was first discovered by the Nobel Prize-winning chemist, Dr. Henri Moissan, at the site of a massive meteorite strike in Arizona. This intriguing new stone was named “moissanite” in his honor. 

    It wasn’t until the late 90s that scientists–working in a research laboratory located in Research Triangle Park, North Carolina–developed the innovative thermal growing process that creates silicon carbide crystals. These crystals are fashioned into moissanite gemstones that rival any natural gemstone for fire and brilliance. These man-made gems are more durable than any other popular gemstone such as sapphire, ruby or emerald.

    Ring Sizing

    Since we handcraft each piece specifically for you, we want to get it right the first time! We highly recommend getting professionally sized prior to placing your order to ensure a perfect fit.  Not everyone wears an even size, therefore many of our pieces are available in half and sometimes quarter sizes (ex: 6.5 or 6.25). Please keep in mind sizing a ring more than 1 size up or down can compromise the structural integrity and potentially cause long term maintenance issues.

    Please note all full eternity pieces can NOT be resized.

    Your purchase comes with a 1-year warranty protecting your jewelry from manufacturing defects. The warranty excludes repairs needed due to user wear and tear.

    Since all fine jewelry is made with malleable precious metals and is certainly not indestructible, we recommend taking special care when exercising, sleeping, swimming or showering in your jewelry. We also recommend avoiding harsh chemicals, lotions, hairsprays and detergents whenever possible to keep your gemstones and diamonds clean and sparkling at their best.
