      Calla, what a wonderful solution you came up with! I learned a lot in this article. Great article! Hi Linda, Your words make my heart sing! Thank you so much. I always learn so much about jewelry from Calla Gold. Thanks again, for educating us about the quirks of platinum.Meanwhile, Calla you are a master jeweler. I really love the ring you redesigned to help your customer fall in LOVE again with her misbehaving wedding ring. Such service and passion you put into to your work…you roar! You are pretty cute there my dear.Thanks for sharing your thoughts! Your Personal Jeweler, Calla Gold. Are you saying that platinum is softer more malleable than gold? Where did you get your information? Hello Christoffer, You are right that pure gold is more malleable than pure platinum. In this blog post I am saying that platinum rings are more malleable than most gold rings.Gold is heavily alloyed with harder metals to give it more strength and toughness. Platinum is much less alloyed when used in jewelry. It is this choice that causes the unintended effect of quicker dulling on a platinum ring than a gold one. Pure gold is more malleable than … Read more ». Would it be better if the ring is faceted? Dear Emi, I think the textural look will make a nice difference in the look of your platinum band. The faceted textural look is a nice look. Platinum Jeweler, Calla Gold.Hello Gem, I had a client with a too thin platinum band with diamonds and engraving. It was doing that muffin top thing on her hand. I also accentuated the comfort fit underneath, that convex shape and that also helped make her finger not do the muffin top puffy look.It really worked out well. Since you have diamonds on … Read more ». Thanks for sharing the valuable information and i hope it helps many people. I too faced the same problem with my platinum ring. It was becoming very dull looking. I had to take it to the jeweler for polish work. Now I know a solution for it. So many people had mentioned this as a problem I felt it was time to write about it.Yesterday I took my engagement ring to get the prong repaired same place as purchased. I brought my thin platnium band along with diamonds half way around and mention I no longer liked it bc the back looks like metal. He said he can smooth it out and it would look beautiful, essentially he would fix it for less than … Read more ». Hi Elise, My guess is that this jeweler polished your platinum ring and rhodium plated it to give it that nice shine. As mentioned above, platinum will always stay white but white gold needs to be re-polished and re-plated occasionally to avoid a yellow hue.This yellow hue usually appears several months to several years, depending on how much wear and tear the ring faces. Because platinum is more dense than gold, platinum rings will be heavier than gold as well. Some prefer the heavier weight, but some find the lightness of gold rings to be more comfortable. It is really up to each individual person. One more benefit of platinum is that it is hypoallergenic. While gold rings do not create an allergy issue for most people, some can develop an allergic reaction from the nickel alloy used in gold rings.Gold, palladium, and platinum can all be engraved without any issue. Another common question we get is what metal choice to pick if getting a ring engraved. We engrave all of our rings for free so make sure you think of something good, and if you need help, here is a list of the best ring engraving ideas. If you decide to go with gold, make sure you pick 14k gold and not 18k gold. While 18k gold is more valuable, it is softer and will scratch easier than 14k gold will.If you have the budget, go for platinum. It is a classic, high end metal that requires less upkeep and keeps diamonds more safe! However, if your budget does not allow for platinum, then gold is a great precious metal that has been used in engagement rings for hundreds of years!When scratched, the scratch will actually displace the metal, leaving ridges on the edges of the scratch. This is where durability comes in. This is why finishes on other precious jewelry wear off, prongs wear down and the rings actually become thinner and even wear through in time. Because many gold products, white or otherwise, are plated, and the plating creates a hard skin, they sometimes seem to have more scratch resistance than Platinum.You will find that soon the plating will wear off and the material will again scratch with daily wear. With Platinum, this is a different story. Many pieces from the turn of the century have engravings that look as good as new, beads that hold stones appear to have just been made and the overall signs of wear seem insignificant on these pieces of Platinum jewelry.A Platinum wedding band will last a lifetime. Polished Platinum, especially the iridium alloys, will display a bright natural white color.In spite of daily wear and scratching, the finish will endure for a very long time.

      Congrats to him and good on him. He also has enough enthusiasm and goodwill to share his experience with others. There is absolutely nothing wrong with that. Many of us know that there can be a lot of other stuff that goes into the BTZ decision, but that doesn't or at least shouldn't detract from whatever good things this particular individual did. Rockwell , Sep 29,  TheSteelPhantom , Sep 29,  Since when did BTZ consist of anything more then a ?When I went up for it years ago? I didn't stand in front of a board of anybody Thankfully my squadron was big enough where we didn't compete with the rest of the base.I would think it would be easier to weigh MX vs MX, instead of everyone else. And OP, first off congrats. Radagast , Sep 29,  Large units 7 or more eligibles receive quotas and promote at unit level. Small units 6 or less eligibles are combined into one pool of eligibles to form the central baseboard CBB population.Quotas are computed and distributed as follows:. Unless the host wing commander establishes written procedures, commanders of large units will establish written selection procedures that ensure the SrA BTZ program is fair, equitable, and provides timely promotion consideration.Once selections are made, large unit commanders underline the selectee s name, date, sign, and return the BTZ eligibility listing to the MPF not later than the last day of the selection month i. The host wing commander will establish written BTZ selection procedures to include method of nominating, number of nominations, timetable to complete required actions, board composition, areas to be considered, scoring scale, announcing selections, and any other required actions necessary to ensure the SrA BTZ program is fair, equitable, and provides timely promotion consideration.The MPF, Career Enhancement Element, will ensure they have received all nomination packages from units with eligibles; if a unit is not going to nominate an individual, ensure a negative reply is received.The following is a list of "approved" board processes:. The following procedures are guidelines and may help establish your BTZ procedures:. Commanders may request supplemental BTZ consideration for individuals that should have been considered by a previous board, and the error is not discovered until after promotions are announced. It is imperative supplemental BTZ consideration is requested only when the unit commander concurs with consideration.Additionally, if the basis for the supplemental request is because the individual did not receive fair consideration or was not considered at all at their last duty station , contact the losing unit and MPF before requesting supplemental consideration, and forward this information along with the supplemental request.If selected, members may apply for a retroactive change to their effective date, according to AFI , para 1.
