Customers can compare the prices of diamonds with similar characteristics in this manner. Grading reports are essential when shopping in this manner because the diamonds' 4Cs quality factors are what distinguishes one diamond from another without seeing the diamonds in person. Make sure you buy a diamond with a certificate from a reputable laboratory, such as GIA. You'll know exactly what you're paying for this way.
It is important to note that two diamonds with the same 4Cs grades will not appear identical. Their proportions and facet placement will still differ slightly, resulting in distinct face-up patterns. This is why many larger online retailers have diamond videos or 360-degree views. These videos will give you a general idea of what a diamond looks like, but the appearance of a diamond may vary depending on the lighting situation.
Before you buy, make sure you understand the company's return policy. You can also buy two to three diamonds to compare and keep the one you like best if the cost isn't prohibitively expensive. Check out the diamonds in various lighting situations to see which one looks best to you overall. Online shopping can also be a great way to research diamond prices before going to a physical store to buy a diamond.
