In Kentucky, engagement ring is “gift in consideration of marriage” which must be returned on divorce. In Walter v.Moore, the court held that a ring given by a man to the woman to whom he was engaged to marry as a token of the engagement is given in consideration of the agreement to marry, although the agreement is not entered into in consideration of the ring being given.[1]
Dec 10, 2018 · The other reason a ring cracks and the more common cause is that your ring has become too thin at the back. Most of the time a ring cracks at the bottom of your ring’s shank, in the middle, under your finger. This is because that spot gets the most stress. Your ring gets more stress than normal at that spot, if it is too large for your finger.
Feb 24, 2022 · A formal examination of whether North Carolina Rep. Madison Cawthorn is disqualified to run for Congress based on the U.S. Constitution won't occur because redistricting changes have moved the location of the district he sought to compete in, a state election official said Thursday.

If we just solder it at the break, and do nothing else, then it is destined to break again in the same place. The first thing I check with a cracked ring is the thickness of the shank. I mean its depth.
A re-shanking involves making your ring’s shank thicker and deeper to give it more strength.
Sometimes you don’t know your own strength. Sometimes the world is an unyielding place. I’ve picked up cracked rings from people who left them on while lifting at the gym.
One of the reasons O-rings can fail is because the material has cracked. If you’ve removed an O-ring from its application and have discovered multiple cracks, you need to understand what’s caused this issue so you can effectively prevent it from happening again.
This mainly occurs in nitrile rubber O-rings, including Buna and Buna-N varieties. Nitrile rubber is a polymer made up of units of carbon, hydrogen and nitrogen. The makeup of the nitrile molecules is such that there is an inherent ‘weak spot’ within the molecule.
The main culprit in o-ring cracking is a chemical reaction between synthetic rubber and ozone known as ozone cracking, or ozonolysis. Ozone cracking typically happens when o-rings constructed from nitrile rubber (Buna-N) are exposed to ozone.
Smart material selection can prevent ozone cracks. Car tires used to have the same problem with ozone cracking that occurs in nitrile rubber o-rings, but manufacturers discovered they could reduce cracks by introducing antioxidants before the vulcanization process.
O-ring users can take a number of proactive steps to prevent cracks. In addition to selecting materials that are resistant to ozone, good storage and handling procedures can reduce crack risks. O-rings should be stored away from common causes of o-ring cracking.
