Moissanite vs Diamond 

If you are considering buying a diamond or moissanite ring, then Jewelry & Gems is the perfect book for you. The book is packed with information and will help you make an informed decision about your purchase. 

Here is a more detailed discussion of the comparison between diamonds and moissanite: 

Diamonds: Diamonds are natural gemstones that are formed deep within the Earth. They are made from carbon atoms that have been subjected to high pressure and heat. Diamonds are the hardest natural substance known to man, and they have a high refractive index, which means that they reflect light very brightly. Moissanite: Moissanite is a synthetic gemstone that is created in a laboratory. It is made from silicon carbide, which is the same material that makes up diamonds. However, moissanite is created under much different conditions than diamonds, which gives it different properties. Moissanite has a refractive index that is even higher than diamonds, which means that it reflects light even more brightly. 

In terms of price, moissanite rings are much less expensive than diamond rings. This is because moissanite is a synthetic gemstone, and it is not as rare as diamonds. However, moissanite rings are just as beautiful as diamond rings, and they have the same brilliant sparkle. 

In terms of ethics, moissanite rings are a better choice than diamond rings. This is because moissanite is not mined in areas where there is conflict or human rights abuses. The diamond industry has been criticized for its use of child labor and its contribution to conflict in certain parts of the world. 

Ultimately, the decision of whether to buy a diamond or moissanite ring is a personal one. There are many factors to consider, such as your budget, your personal preferences, and your ethical concerns. If you are looking for a beautiful and affordable alternative to diamond rings, then moissanite is a great option. 

Here is a table summarizing the key differences between diamonds and moissanite:

Hardness 10 on the Mohs scale 9.25 on the Mohs scale

If you are still undecided about whether to buy a diamond or moissanite ring, then I recommend talking to a jeweler who can help you make the best decision for you.
