In one sentence, describe what the following article is about: Look at the inside of a ring's band to find the hallmark that indicates the platinum purity. Find this marking as a sure way to determine that the ring is truly made of platinum.  You may need a magnifying glass to see the fine engraving on a small ring. If there is no engraved hallmark, the ring is not platinum, or is made with less than 50% of it and cannot be considered and marked as platinum. Check the inner band for a symbol that you can use to quickly identify if the ring is made with real platinum. The type and presence of the symbol depends on the country of origin; sometimes there may only be words and numbers instead of a symbol.  In the U.S., you will see a symbol that resembles a house shape (triangle atop a rectangle), or simply a combination of letters and numbers. In India, you will find a symbol created by an uppercase “P” and a lowercase “t,” followed by the number 950. In China, you will find the English letters “Pt,” perhaps alongside other Chinese characters. In Japan, you will see “Pt” followed by the number 850, 900, 950, or 999. Look at the numbers and/or letters that are given as part of the platinum hallmark. The letters will designate the ring as platinum, while the numbers indicate how many parts out of 1000 are pure platinum by weight.  If letters are given, they will say either PT, PLAT, or PLATINUM, which indicates that the ring is at least 95% platinum.  In the U.S., the number given before or after these letters can be 850, 900, or 950. This indicates that the ring is made with 85%, 90%, or 95% pure platinum, respectively. The other percentage of the ring composition is a metal that the platinum is alloyed with to make it harder.
Summary: Locate the hallmark on the inside of the band. Look for a symbol that indicates platinum. Read the letters and numbers of the hallmark.

In one sentence, describe what the following article is about: Are you really still in love with him? If so, it might be worth trying to get him back, by showing him you still care and that you believe things will be better this time. Sometimes breaking up provides time for both people to realize that, more than anything, they just want to be together again. However, if you have any other reason for wanting your ex back, reexamine whether it's a good idea to try to rekindle the relationship.  For example, if you want him back because you feel lonely without him, that's not a good enough reason to get back together. The lonely feeling will pass with time. Or if you want him back because you feel jealous thinking of him with someone else, think again before you decide to try to get back together. Post-breakup jealousy is normal, and this, too, will pass. If your ex boyfriend has started dating someone else, consider him off-limits. Don't become that person who won't leave her ex alone after he has moved on. If he's happy with someone else, you could end up hurting him, his new partner, and yourself by trying to interfere. It might feel temporarily lonely or even boring to be on your own after the end of a tumultuous relationship, but try to ride that feeling out instead of going back to your ex. On again, off again relationships tend to be based on unhealthy patterns that won't go away. Resist the temptation to jump right back in when you know you're better off without him.
Summary:
Make sure you want your ex boyfriend back for the right reasons. Think twice if he's already in another relationship. Stop trying to get your ex back if the relationship was toxic or abusive.
