Selecting a Diamond…Carat

When trying to select a diamond you will hear the 4 C’s over and over again. Clarity, Color, Cut and Carat. Carat refers to the weight of a diamond. The higher the carat weight, the more valuable it is (other factors being equal). There is a slight formula that goes into calculating the carat of a diamond. A carat weighs 200 milligrams and is divided into 100 points. So, if you have a  .5 carat diamond it is exactly the same as if you had a 1/2 carat diamond which is the same as a 50-point diamond.

Over a carat, diamond weights are usually expressed in carats and decimals. A 1.06 ct. stone, for example, would be described as “one point oh six carats,” or “one oh six.”

This word for the measurement of a diamond’s weight Carat – is derived from the carob seeds that were used to balance scales in ancient times.

This is an important factor to evaluate but is not the most important one. When selecting the size be sure that all the C’s are taking into consideration. You could put all your money into a 2 carat diamond ring, but with poor clarity, color and cut it does not have the value of many smaller stones. The other three C’s like clarity, cut and color determine the visual brilliance of the jewelry. Don’t be fooled by the size, you can find a beautiful, affordable engagement ring in Boston with BRAG jewelers that will make her say yes!

What Is Ring Insurance?

Your jewelry is priceless to you but there is an actual cost of replacing your beloved jewelry in the event that you have a loss. For extra peace of mind we highly recommend you insure your jewelry especially if it worn daily. Did you know that with jewelry insurance you covered worldwide against loss, theft, damage, and mysterious disappear. When you purchase jewelry from BRAG, we will always provide you with a complimentary appraisal so you can acquire insurance.  You will need just an appraisal from BRAG, not the bill of sale what you actually payed may not be the current market price; replacement should always be based on replacement cost not actual cost. NEVER give your bill of sale. We have complimentary appraisal update for jewelry purchase from Boston Ring And Gem. We recommend you stop in every three years and have us check things out and make sure you have no imminent threat.

How ring insurance works

We believe that “discounted” insurance is better than no insurance, but based on our experience we have had the best results with Liberty Mutual as a personal property policy on your homeowner or renter, and Jewelers Mutual insurance which is a separate insurance policy from your homeowner/renter policy. Jewelers Mutual offers additional preventive repair, they would rather pay to have smaller problems fixed before they become larger, so your diamond engagement ring  that is worn daily will eventually need to have some preventative maintenance even though we perform those service for cost of labor and material for BRAG setting,  Jewelers mutual will pick up the tab.  If you are planning a move make sure your insurance follows you to the new location, so you can move with confidence.

Oval Cut Diamond Engagement Rings

For those looking for a ring that has the look of a round diamond but want something more unique than the oval diamond cut is the diamond you want. Another advantage of oval shaped diamonds is it can be perceived to be bigger than it actual is as well as make the person wearing it look as though they have a longer, slimmer finger.

When deciding on how narrow or fat the diamond should be is up to the individual, but for your own knowledge, a length to width ratio of 1.35 – 1.50 is considered the classic oval cut. If the end result includes the diamond flanked by side stones, a slightly thinner diamond cut will give you a great appeal. A BRAG representative can walk you through the processing and help create the best diamond engagement ring using the oval cut.

If you are interested in purchasing an oval diamond or want to learn more about them, contact a BRAG today!

Engagement Ring Care Tips by BRAG

Now that you have an engagement ring that your significant other has invested in to show you how much they love you, take care of it! The diamond engagement rings that we have at Boston Ring and Gem are beautiful, timeless and too good too be mistreated. Learn some easy ways to keep your engagement ring in the best condition possible.

Don’t be afraid to remove it!

“Never take it off!” I bet you have heard that before, but sometimes to protect your engagement ring from damage, you may have to take it off! Here are few example of activities that might require you too remove it!

  • Playing sports, lifting weights and other activities.  As for taking your ring to the gym, lifting weights with it on can also be hazardous. You wouldn’t want a 25-pound dumbbell making contact with your stone.
  • Gardening and hands-on-work can cause damage. It is possible to chip your diamond or knock the setting loose while doing heavy yard work.
  • Harsh chemical soaps or cleansers can soil the ring. It’s also a good idea not to wear your ring while doing the dishes.

Avoid Harmful Products

Keep your engagement ring sparkling by eliminating the gunk and dirt that can make your diamond cloudy.  Products like lotions, sunscreens and perfumes should put on with your ring off!

Get your Setting Checked Regularly

Boston Ring and Gem can check your setting for you to ensure that  the stone hasn’t been knocked loose, especially if it is particularly large. Usually every six months, it is ideal to have the setting checked.

Insure Your Ring

Thinking the worst, you loose your diamond wedding ring! Getting your ring insured is the best way to make sure you are covered. Look into what your home insurance offers and insure it separately, but do that first!

How To Clean Your Engagement Ring at Home

There is nothing better than seeing your diamond engagement ring catch your eye or the eyes of strangers.  It is only natural to want to maintain that sparkle by keeping it clean on a regular basis. However, if cleaned improperly you can permanently damage your engagement ring.

Before you start attempting things that you heard from a friend of a friend, the diamond experts at BRAG jewelers in Boston MA can tell you how to clean your engagement ring safely and what to avoid at all costs.

First, let’s try to figure out what it is that is making your ring so dirty. If you are outdoorsy or spend your days in the kitchen environment, let the Boston jewelers at BRAG professionally clean your diamond ring or jewelry. It is best to get it cleaned at the jewelers using quality professional-grade products that will restore the brilliance of the diamond safely.

If your engagement ring is dirty from everyday common products like: hairspray, lotion, makeup, or perfume a easy at-home cleaning should do that trick. All you need is warm (almost hot) water, dish soap and a very soft toothbrush. Get a small enough container not to loose it or have it accidentally dumped down a drain! Soak your ring for about 20 to 40 minutes, gently brush the stone with the toothbrush, and rinse it under warm running water. Repeat the process if necessary.

How NOT to clean your engagement ring.

Any household cleaner should not even be considered. If you start reaching for things like bleach, chlorine, and acetone, stop now! These chemicals are far too harsh and can break down the base metals in your ring! While we are on the topics, never use any abrasive products such as toothpaste, baking soda, or any powdered cleaners, which can easily scratch metals. The damage these cleaners will cause will be costly to undue.

Anything that runs on battery or electricity is also something to avoid. These powered jewelry cleaners can weaken prongs or dislodge a stone. If you think a machine is required, bring it to BRAG jewelers conveniently located in Downtown Boston MA, where we can fix anything that might become loose.
