Moissanite - Francois Jewellers
Wearing Moissanite is much like dazzling your audience with a disco-ball colour effect. Its colours are more brilliant than a real diamond and will dazzle all admirers. A leading South African manufacturing jeweller who uses Moissanite is FRANCOIS JEWELLERS. Not only is it an affordable alternative to a diamond but it is a gemstone in its own right.
Where did the name Moissanite come from?
A French scientist, Dr. Henry Moissan, first discovered Moissanite in 1893 in a crater that was created by a meteor. His first thought was that he had discovered diamonds, but later found that these crystals are composed of silicon carbide whereas Diamonds are composed of carbon. However, Henry was awarded with the Nobel Prize in chemistry. Hence, it named with Henry’s last name, “Moissanite”. Moissanite is a gemstone like any other precious stone. It is a crystal form of silicon carbide. Natural moissanite is very rare. Moissanite available commercially today are lab-created.
Why should I choose Moissanite as a Diamond alternative?
Moissanites offer an ethical alternative to Diamonds. Young couples who need to stretch their cash to cover wedding costs can happily settle for a Moissanite engagement ring. Not only does it look and feel like the “real thing”, but it also costs a fraction of the price of a diamond. Apart from saving cash, the bride can rest assured that there will be as much oohing and aahing by jealous girlfriends.
The price for a 1.00 carat Diamond of the same carat weight, colour and clarity as a Moissanite in South Africa is about R200,000. On the other hand, the compared Moissanite will cost you about R10,000!
FRANCOIS JEWELLERS Moissanite range varies from colourless to near colourless. That means it is comparable to a Diamond of D to F colour. Moissanite stones are suitable for use in all metals – Palladium, Platinum, Rose-, Yellow- and White Gold as well as Sterling Silver.
Why a Moissanite from FRANCOIS JEWELLERS?
- All stones weighing 0.50 carats and above have been graded according to gemological standards by a Laboratory. These stones are each allocated with a unique serial number that is laser engraved on the stones’ girdle which is also stated on the Laboratory certificate.
- FRANCOIS JEWELLERS’ Moissanite stones have a Limited Lifetime Warranty. This warranty protects buyers against manufacturing defects.
- In the event of loss or theft, your Moissanite purchase from FRANCOIS JEWELLERS will be blacklisted on the Laboratory’s database, effectively preventing the stone from being registered by a third-party.
Moissanite has created an entirely new and unique category of gemstone for jewellery…… exceptionally brilliant and amazingly unique. Moissanite produces the most fire and sparkle you’ve ever seen and to give you comfort, is sold with a limited lifetime warranty assuring that its brilliance will never fade. Moissanite is not a Diamond simulant, but an entirely unique gemstone with highly desirable qualities and an affordable alternative. The fire, brilliance and sparkle that are so characteristic of Moissanite is due to its high refractive index of 2.42. The higher the refractive index of a gemstone, the more fire it emits. Measuring Moissanite’s fire of 0.104, it is more than twice that of a Diamond, which measures 0.044. Simply, when comparing them side by side, Moissanite emits more fire, or flashes of rainbow coloured light, than a Diamond. Moissanite has a double refraction. When you look closely with a loupe or magnification glass at the stone through the crown, you may find the double refraction of facets. Moissanite has extreme brightness and fire compared to diamonds and cubic zirconia. If you find extraordinary flashes of colour, it’s probably Moissanite. Fire and brightness in Moissanite are two times more than diamonds because of the said double refraction. A Diamond is always single refractive.
Whereas diamonds are measured in carat, Moissanite are measured in mm. A 6.5mm diameter Diamond weight approximately 1.00ct whereas the weight of 6.5 mm diameter Moissanite stone varies between 0.83 to 0.88 carat. This is because Moissanite is 14-18% lighter than diamond. D.E.W. means Diamond Equivalent Weight. A 6.5mm Moissanite is also referred to as “ 6.5mm Moissanite (1.00ct D.E.W.)”, a 5.0mm Moissanite as “0.50ct D.E.W.”, a 7.5mm Moissanite as “1.60ct D.E.W.” Click on Diamond conversion chart to see the mm to ct conversions.
FRANCOIS JEWELLERS only stocks colourless to near colourless (Diamond Colour comparison colour D to F) Moissanites.
Moissanite stones sold by FRANCOIS JEWELLERS have no eye visible inclusions. When using magnification, one can see characteristic needle like “lines” which are typical and inherent to crystal growth process in Moissanite. Moissanite inclusions are mostly caused by micropipes (the lack of material) which is invisible to the naked eye and very difficult to see under a microscope. These micropipes are unique to Moissanite.

Moissanite are precisely hand-cut by a master gem cutter. This allows the gem to display the beautiful fire and brilliance and creates the maximum sparkle which intensifies its ultimate fire.
Moissanite vs. Diamond
Moissanite has many similar physical properties to those of Diamond and will test positive for Diamond when using a thermal Diamond tester. Therefore a standard Diamond tester cannot be used to determine if the gemstone is a Moissanite or a Diamond. There are three methods to distinguish Moissanite from other near colourless gems.
- ◊ Using a special electronic tester that distinguishes between Diamonds, Moissanite and Diamond simulants.
- ◊ Using a 10 x (or higher) magnification loupe look for needle-like or micro-pipe type “lines” that typically are perpendicular to the table facet. These “lines” are visible only under magnification.
- ◊ Using a 10 x magnification loupe, determine if you can see the doubling of facet junctions. This is quite difficult and will require some practice.
If you are investigating all possible avenues for the purchase of an engagement ring, Moissanite must be one of your top choices. While it is often far more expensive than Cubic Zirconium (CZ), there is no comparison when it comes to quality differences. CZ are much softer, making them susceptible to scratches and abrasion. These stones also lose their lustre over time. Moissanite, on the other hand, is one of earth’s toughest and hardest elements.
PLEASE BE AWARE OF VERY INEXPENSIVE LOW GRADE MOISSANITES!! THEY LOOSE COLOUR OVER TIME, SCRATCH MORE EASILY AND ARE NOT AS DURABLE AS THE HIGH QUALITY LABORATORY CERTIFIED MOISSANITES FROM FRANCOIS JEWELLERS!
Moissanite is extremely scratch and abrasion resistant. Moissanite is 9 ¼ on the Mohs scale and is the second hardest gemstone used in jewellery after a Diamond. It is one of the toughest jewels known and is harder than all other gemstones (excluding Diamond) including ruby and sapphire. Based on measurable scientific studies in high pressure research, Moissanite is extremely resistant to breaking and chipping. Moissanite has been tested to temperatures higher than 1000 degrees centigrade. At this temperature, Moissanite remains intact and remains as brilliant as the day it was created. Moissanite’s heat resistant properties are excellent.
Moissanite vs. Cubic Zirconium
Compared to Moissanite, Cubic Zirconium is substantially softer. Cubic Zirconium scratches and abrades easily. This is why it loses its lustre after a relatively short time. Frankly, there simply is no comparison between Cubic Zirconia and Moissanite. Compared to Moissanite, Cubic Zirconium has very little sparkle. Moissanite are far superior to Cubic Zirconia. Moissanite is one of the hardest and toughest known elements on earth, making it extremely resistant to scratching, chipping and breaking.
Moissanite can be cleaned the same way as you would clean your Diamond and other fine jewellery. Normal ultrasonic cleaning is perfectly safe and advisable. Do not place more than one piece of jewellery in the ultrasonic cleaner as this can damage or chip any jewellery due the high frequency and vibrations. You can also clean Moissanite with a commercial (non-acid based) jewellery cleaner (contact us) or use mild soap and water with a soft toothbrush.
