OgilvieGems have a passion for custom tailored designs. We cannot restrict ourselves to just a singular brand or precious stone. OgilvieGems specialize in Charles and Colvard Certified and Created Moissanite, GIA Certified Diamonds, Natural and Lab Created Sapphire, Natural Moragnite, Lab Created and Natural Emerald, Lab Created and Natural Rubies as well as other gemstones.

OgilvieGems only deal in GIA Certified Natural Diamonds. OgilvieGems believe in using only the best in our hand crafted designs;  and in our personal opinion as jewelers, we have decided that GIA are the only route to go.

No. There are no likely situations in which the color of moissanite will be permanently changed. Moissanite does undergo a temporary color change when exposed to extreme heat from a jeweler’s torch during jewelry repair, but with proper bench techniques there will be no lasting damage, and the stone will return to its normal color once it cools

Yes. Moissanite can have needle-like inclusions that can be seen under 10x magnification. However, they are not visible to the naked eye and do not affect the clarity of the stone. They are unique characteristics, which occur in the formation of the crystalline structure.

Yes. Moissanite is durable, tough and extremely resistant to scratching and abrasion. With a hardness of 9.25, moissanite is harder than all other gemstones except diamond.

Charles & Colvard Forever One moissanite is a triumph of art, science and sustained effort. The structural configuration of this new moissanite material is what yields its unsurpassed, colorless (D-E-F) quality. While chemically it is still silicon carbide (SiC), and its optical and hardness properties remain the same, it is the stacking of SiC material in the manufacturing process that makes Forever One moissanite unlike any of its predecessors.

Through its research and development efforts working with Forever One, Charles & Colvard has developed a second grade of Forever One, in G-H-I quality*. This near colorless gemstone emits a faint, icy hue compared to its Forever Brilliant predecessor, which yields a warm hue. This new, near-colorless gemstone is only currently available in limited quantities on the Charles & Colvard® e-commerce website,

Please note: OgilvieGems only retail Forever One Colorless and Near Colorless and that Forever Brilliant and Classic is no longer an Offering From Charles and Colvard.

Forever Brilliant moissanite falls within the prized, near-colorless G-H-I range. Forever Brilliant was developed through improvements to the crystal growing process from the original brand of Charles & Colvard created moissanite also known as Forever Classic. Forever Classic offers subtle color shades in the J – K range of the industry color scale, with faint undertones of green, yellow or gray. Forever One D-E-F, Forever Brilliant and Forever Classic moissanite gemstones and jewelry will continue to be made available to wholesale distributors, manufacturers, retailers, TV shopping networks and designers.

*Based on the Gemological Institute of America’s diamond grading scale.

The carat is the traditional unit of measurement for a diamond’s weight. Moissanite is not measured in carats because it weighs approximately 10 percent less than diamond. For example, a 6.5mm round diamond would weigh 1.0ct, while a 6.5mm round moissanite would weigh 0.88ct. The two stones would be the same size – 6.5mm in diameter. All stones for sale are listed with their size in millimeters and the diamond equivalent weight (DEW) in carats.

You may clean moissanite the same way you would diamond or any other fine gemstone. As with any fine jewelry item, an ultrasonic cleaner can be used. However, it is best to be gentle with your valuable treasures. You can also clean your moissanite jewelry using a commercial (non-acid based) jewelry cleaner or with mild soap and water using a soft toothbrush.

There are four C’s jewelers use when grading gemstones…and they tell you everything you need to know about moissanite to achieve the fifth C – which is Confidence. The quality and enduring value of moissanite jewelry can be expressed in those 5C’s and every Charles & Colvard and OgilvieGems Created Moissanite is strictly examined by our experienced Gemologists.

Every Created Moissanite gem is precisely calibrated and hand-faceted by master gem cutters to maximize brilliance and spark its ultimate fire that increases the refractive index of moissanite.

Moissanite is graded as near-colorless, with faint undertones of green to yellow to gray, and a few rare green gems. 

Moissanite’s clarity grading is “eye-clean”. Our moissanite are created using organic elements, mimicking nature in a controlled environment, therefore moissanite gems have tiny, needle-like inclusions that invariably develop during the growing process of moissanite. However, only moissanite gemstones that pass OgilvieGems quality standards are made available for distribution.

Moissanite is visually proportionate to typical diamond carat weights but is approximately 10% lighter. Most jewelers find it easier to sell moissanite by size rather than weight. A 6.5mm round brilliant natural diamond would have a carat weight of approximately 1.0 compared to a moissanite of the same dimension (6.5mm) which has a carat weight of approximately 0.88. Simply put, to the eye they appear to be the same size, although the weight of the two stones may be slightly different.

Like other gems, large sizes of moissanite are rare. However, the premium for large sizes is much less, making moissanite a particularly good choice for bold jewelry designs.

Known to many as “The World’s Most Brilliant Gem”, with unsurpassed fire and brilliance, this unique created gemstone is the ultimate in gemstone design.
