If you’re looking for low pricing and in-person shopping, it’s a good idea to check out Costco. As long as they’re certified by the Gemological Institute of America, the diamonds from Costco are of decent quality and offer good value. It is possible to find a ring for 50% less than at other big-name jewelry stores.
For in-person shopping, it’s best to go to one of their warehouses located throughout the US, as well as to some of their large-format stores located in larger cities. Costco will also offer a diamond grading service.
A Better Alternative: It may not be as low priced or convenient as going to a warehouse, but if you want to see a certified stone, we recommend going to a local jeweler. You’ll probably pay more per carat than you would at a warehouse, but you’ll get a better product and have more options. Diamonds are a girl’s best friend, but there are other stones that are just as valuable and can be used for engagement rings and wedding rings.
Take the case of white diamonds.
If you’re looking for a white diamond, you’re not going to find the perfect one at a jewelry store. Most white diamonds are man-made, and will not have the same lustrous brilliance as a natural diamond. White diamonds that are mined are graded and graded as being lower in quality than the natural diamonds. They are not nearly as valuable as natural diamonds, and the price per carat is not as good as it is for natural diamonds.
When it comes to purchasing a white diamond, you’re better off going to a reputable jeweler and having a stone certified by the Gemological Institute of America. The GIA is the standard for determining the quality of a diamond.
