Human: What are the benefits of natural diamonds? Assistant: 
The main benefit of natural diamonds is that they are extremely durable and can withstand high temperatures, making them a popular choice for jewelry. They also have a very high refractive index, which makes them highly reflective and sparkly. Natural diamonds are also known to be hypoallergenic, meaning people with allergies or skin sensitivities may find them easier to wear. Additionally, diamonds are one of the hardest natural materials known to man, making them an excellent choice for industrial applications such as cutting tools and drill bits.
