Diamonds are actually limited, and it takes millions of years to form underground. Therefore, the diamond ring is worth collecting, but the diamond ring worth collecting needs to meet certain standards. Some diamond rings with broken diamonds and poor colors are not worth collecting. Generally, diamond rings with a collection value of more than 1 carat, more than H color, more than VS2 clarity and 3EX cut are available. Of course, the price of a diamond ring that meets this standard is very high, but if you buy it from a cost-effective brand like Blue Nile, you can also own such a diamond ring at a price 20% to 40% lower than other brands.
