MoissaniteEngagementRings

Moissanite is a gemstone made of silicon carbide. It was first discovered in 1893 by the French Nobel chemist Henri Moissan, who found tiny crystals of it in the rock of a meteor crater in Arizona and at first mistook them for diamonds. Natural moissanite is far too rare to use in jewelry, so the moissanite in these rings is grown in a laboratory, where the crystal can be built to a consistent, high standard. The result is a hard, brilliant, near-colorless stone with more fire than a diamond, born from a discovery that quite literally fell from the sky.

No, and we would never tell you it is. Moissanite is its own gemstone, silicon carbide rather than the carbon a diamond is made of, and it has its own look and its own strengths. It actually returns more brilliance and considerably more rainbow fire than a diamond because it bends light more sharply, and it is doubly refractive, an optical property diamonds do not share. It rates 9.25 on the Mohs scale, just under a diamond's perfect 10 and above a sapphire. It also costs a small fraction of what a diamond does for the same size. Moissanite is not a diamond and it is not trying to be one. It is a beautiful stone chosen on its own merits, most often for its fire, its toughness, and its value.

Honest answer: no, not an individual lab report. The moissanite centers in this collection are calibrated stones, meaning they are cut and sorted to precise, repeatable specifications by size, shape, color, and clarity rather than graded one at a time the way a diamond is. That is part of what keeps them so affordable, and it is standard for moissanite across the industry. What we do promise is real: every center is premium DEF near-colorless, in the D to F range at the top of the color scale, and eye-clean, meaning no inclusions are visible to the naked eye. These are the same grade and standard as the well-known Charles and Colvard moissanite. If you would like formal documentation of the exact stone, our concierge can talk you through the options before you order.

Often it will pass a basic thermal diamond tester, because moissanite conducts heat in a similar way to diamond, which is one reason Henri Moissan mistook it for one in the first place. Modern testers that also read electrical conductivity or reflectivity are built to tell the two apart, and most jewelers now carry them. We share this so you know exactly what you are buying: a stone that looks superb and reads bright to the eye, but that is its own material, not a diamond. We never market moissanite as a way to fool anyone.

No. Moissanite does not cloud, does not fade, and does not lose its color or fire with age. It is one of the most stable gemstones you can wear, and at 9.25 on the Mohs scale it resists scratches and everyday knocks extremely well, better than a sapphire and close to a diamond. Ordinary care is all it needs: a rinse in warm water with a little dish soap and a soft brush brings back its sparkle. A moissanite engagement ring is built to look as bright on your fortieth anniversary as it did on the day of the proposal.

This is where moissanite shines, quite literally. Because it costs a fraction of what a diamond does per carat, the same budget buys you a much larger, brighter center. A size that would be a serious stretch in a mined diamond sits comfortably within reach in moissanite, and shapes like the oval, pear, and marquise face up even larger for their weight. Every ring lists its center sizes as choices, so you can dial the look up or down and watch the all-in price move with it. Many people choose a size in moissanite they simply could not justify in diamond, and no one can tell from across the room.

Start with the shape that fits her taste. A round is the timeless, most brilliant choice; an oval or marquise reads long and large for its weight; a pear is distinctive and romantic; a cushion is soft and vintage; an emerald is cool and architectural; a princess is crisp and modern. Then pick a setting: a solitaire keeps all eyes on the stone, a halo or hidden halo adds sparkle and size, pavé and channel-set bands line the shoulders with light, a three-stone design widens the whole face of the ring, and baguette or cathedral settings bring an architectural, heirloom feel. There is no wrong answer, only the one that suits her hand.

Yes, and that is the whole point of how this collection is built. The price on each product page is the complete ring: the setting, the moissanite center shown, and the labor to set and finish it in your size. There is no separate stone to add at checkout, and no setting-only sticker made to look cheaper than the real cost. Choose your metal and center size, and the number you see updates to the true, final total.

Every moissanite engagement ring is finished to order in the size you choose, so it arrives ready to propose with. If you are buying as a surprise and do not know the size, order close and we can adjust, or request our free ring sizer. Because these are made to order, most orders ship in roughly one to two weeks; the exact window is listed on each product page and in your confirmation. If you are working toward a specific date, tell our concierge and we will confirm the timeline first. Every ring ships fully insured and free, with a return window and a warranty on the setting.

Very little is required. Because moissanite is so hard and so stable, it keeps its shine with almost no effort. Soak it now and then in warm water with a drop of mild dish soap, work gently around the stone with a soft toothbrush, rinse, and pat dry. Avoid wearing it during heavy manual work or with harsh chemicals, the same sensible advice for any fine ring, mostly to protect the metal and the setting. Have a jeweler check the prongs once a year and your ring will stay secure and brilliant for a lifetime.
