Just wondering, what is the best way to keep my diamonds rings sparkling without destroying their settings?One is set in platinum and the other white gold. Someone told me that it was OK to mix windex and H2O and soak the rings. Can this hurt in anyway?Also, not only does my diamond reflect all the colors of the rainbow, but at times it reflects pink and yellow...is this a normal effect?Lastly, it is amazing to see how much there is to know about purchasing a stone. My father gave my mom a marquise 35 years ago. He looked at only 1 other stone. The marquise is approximately 2 CT and he paid $1,500. Today, we pay $15,000+...that is a scary thought. How will our children be able to afford this luxury?Thank you for your response.
