This is because it will help you to ensure that you are picking the right type of diamond ring that suits your bride. Several customers who are looking for engagement rings often ask what is the price of a 1.5-carat diamond ring. If this question is bothering you too, then you should note that the average cost of a 1.5-carat diamond ring is around 1000 dollars. However, if you do not have such a budget, it is best to look for use diamond rings or wait for deals at online retail stores. On the other hand, customers who are moving forward with the decision of buying a 1.5-carat diamond ring should make sure that their preferred diamond ring is certified. Some jewelers may try to outsmart you by claiming that certifications do not matter, but do not fall for such talks, as they might be trying to sell fake diamond rings to you. Do not rely on in-house grading reports either; instead, thoroughly examine the diamond ring certification by GIA or such reputed and recognized institutes.
