Online purchases are often less expensive than wholesale and retail purchase. Given below are three things about buying diamond rings that need careful consideration. Diamonds You can either purchase loose diamonds that can be set on ring later on, or mounted diamonds that are already set. Generally, buying a loose diamond will be a good choice, as you can see it from all sides and check if there is any visible flaw in the stone. On the contrary, mounted diamonds are already set and can hide some visible flaws. Band Metal When you buy online diamond ring, you should choose an appropriate band metal too. Platinum is the hardest and most durable metal that can be used in the band. So if your ring consists of a highly priced centerpiece, you can go for a platinum band. Otherwise, white gold, yellow gold, or rose gold will be a good choice. In any case, make sure it matches with the centerpiece. Band Setting Providing an apt setting for your diamond ring is very vital to protect the stone safely. Prong settings and bezel settings are the two widely used settings. The former allows more visibility of diamond and are easy to clean. However, the stones can be vulnerable to damages in this case. Thus, the latter will be the best pick for a safer option.
