Solitaire Rose Gold

Natural moissanite is extremely rare (rarer than natural diamond). That is why the vast majority of moissanite is created in a laboratory.

Visually identical to a diamond

• To the human eye, it is impossible to tell moissanite and diamond apart.
  
  
• You need a diamond/moissanite tester to measure the difference. In fact, a diamond tester based on thermal conductivity will wrongly register moissanite as diamond, because the two stones are so alike.

The world's second-hardest gemstone

• After diamond, moissanite is the hardest gemstone in the world. It measures 9.25/10 on the Mohs hardness scale.

The world's most brilliant gemstone

• Moissanite has more brilliance than diamond. When light hits a diamond, the same white light is refracted and reflected back out of the stone. When light hits moissanite, however, it splits in two, which increases the refraction.
  
  
• Moissanite has a refractive index of 2.69 (compared with diamond's 2.42) – noticeable to a moissanite tester, but not to the human eye.

More "fire" than diamonds

• "Fire" is a gemstone's ability to disperse white light into the colours of the rainbow.
  
  
• Moissanite has more "fire" than diamond, with a value of 0.104 (compared with diamond's 0.044).
  
  
• Moissanite has 5–7 times more "fire" than ruby, sapphire and emerald respectively.
  
  
• This means moissanite outshines almost every other gemstone in the world.

An ethical alternative to a troubled diamond industry

• Sadly, the diamond industry has been linked to many tragic problems, including serious human rights abuses. Poor planning and organisation have also caused major environmental damage, with land and water so badly affected that entire ecosystems have collapsed.
  
  
• Our moissanite is a 100% ethical, conflict-free material that is almost identical to diamond. It is not mined but grown in a laboratory (each moissanite gemstone takes 2–3 months to grow). This makes it far easier for us to ensure ethical practices around our moissanite and to check the quality of every single stone. Natural moissanite is extremely rare and often has inherent flaws.

MATERIAL GUIDE — WHAT OUR JEWELLERY IS MADE OF

We believe in being completely open about what you are actually buying. Here is everything you need to know about the materials in Chiaro jewellery.

925 sterling silver
The core material of all our jewellery is genuine 925 sterling silver — 92.5% pure silver alloyed with 7.5% copper for strength and durability.

Gold plating
Our gold and rose gold variants have a gold plating applied by electroplating. This gives the piece its colour and shine. As with all jewellery plating, it is not indestructible — it can gradually fade with daily wear and contact with water, perfume and creams.

Care tips for making the plating last as long as possible:

• Take the jewellery off before showering, bathing and exercising
• Avoid contact with perfume, creams and cleaning products
• Store dry and separately from other jewellery
• Wipe gently with a soft cloth when needed

Moissanite
The stone in our jewellery is moissanite — a lab-grown gemstone with a hardness of 9.25 on the Mohs scale (second only to diamond) and high brilliance. Moissanite is not a diamond, but has its own strong sparkle and is far more accessible in price.

Our stones have colour grade D (the highest grade), 0.41 carat, 5 mm diameter.
