Congratulations! You've met the woman you want to spend your life with. That was the easy part. Now you have to make many decisions about your future together. Usually, the first one you need to make is about a Diamond Engagement Ring. And that's not nearly as difficult as it may seem. Men in love have been doing it for hundreds of years. Now that you've found the perfect woman for you, make sure you find the diamond that suits her perfectly. Because, just as your love for each other is unique, no two diamonds are alike. Each has its own personality and sparkle.


If you're like most grooms-to-be, not enough. But chances are you've noticed a friend's or relative's beautiful Diamond Engagement Ring and the pride she takes in wearing it. After all, a Diamond Engagement Ring is more than a piece of jewelry. It's an enduring symbol of the love between two people.

It's easier than you may think to select a ring that's sure to make your fiance's eyes light up. Whether she's discussed her preferences with you or dropped not-so-subtle hints, you don't have to go it alone. Visit us and take note of those rings that seem to appeal to her. The enthusiasm of the bride-to-be is your best barometer of what style to select. Later, you can return alone and make the purchase.


This is an important consideration. You should know that the quality of a diamond has nothing to do with size or color alone. But it has everything to do with the 4Cs: Cut, color, clarity and carat weight.


Many people confuse cut with shape. A diamond's cut is what gives it its fire and sparkle. When cut to good proportions, the diamond is better able to handle light, creating more sparkle and scintillation.


The best color for a diamond is no color. A totally colorless diamond best allows white light to pass effortlessly through it and be dispersed as rainbows of color. Yes, there are very rare pink, blue, and green diamonds. Theses are known as 'fancies.'


Most diamonds contain very tiny natural birthmarks know as inclusions. However, the fewer and smaller the inclusions are, the less likely it is that they will interfere with the passage of light through the diamond. Diamonds, more than any other gemstone, have capability to produce the maximum amount of brilliance. Most jewelers have a rating system that will help you understand the clarity of your stone.


This is the weight of the diamond measured in carats. One carat is divided into 100 points. So a diamond of 75 points weighs .75 carat. Carat-weight is the easiest of the 4Cs to determine. But two diamonds of equal weight can have very unequal value, depending on their other characteristics. Fine quality can be found in diamonds of all shapes and sizes. And a fine quality diamond is a little extra weight she'd be pleased to put on.

Our jeweler is the diamond expert and will be happy to explain the 4Cs and show you the differences between various qualities of diamonds. Our established jeweler prizes his good reputation and will help you choose the best quality diamond, your primary consideration when making this purchase.


The precision with which your diamond is cut will determine its brilliance, its fire, and its ultimate beauty. However, the shape you select is a matter of personal taste. The round brilliant is the most popular shape, but there are many others, such as the oval, marquise, pear, emerald and square.

Today the emphasis is on simple, elegant designs that highlight the beauty of the diamonds themselves. So you can never go wrong with the classic Diamond Engagement Ring.

    “Unbelievable, hassle free experience. From texting back and forth with Josh on a Saturday on the VIP event and the engagement ring options, to receiving and email from Dave that night with options for me to review to Tuesday going in and going in and purchasing while having a beer while I waited. Outstanding experience. Well done!”

The designers and Beth helped me work through my thoughts to create a piece that has deep meaning. Beth was amazing to work with and was patient with all my ideas. Thank you Beth and the team of designers.”

    “I can’t rave enough about my experience with Marks Jewelers. Olivia spent hours with me to design a couple pieces of jewelry with stones I had and Jacqueline created a couple of molds perfecting it. The end result is better than I ever imagined. My experience was so personalized and professional. Quality and a great price!!”

    “I needed a 3-tier tier pearl necklace restrung and I brought it to Mark's Jewelers. Although it is costume jewelry, it has much sentimental value to my wife. I wasn't sure if they would work on costume jewelry oh, but they did! They did a fantastic job! The drop-off and pick-up experience was terrific! Everyone was so professional. I highly recommend this place! I will be back!”
