Jewelry & Diamonds

As experienced jewelers under the leadership of Bryan Blaha (Master Jeweler) we have cultivated and grown under the idea that quality and relationships are what make us different. Unlike the “Mall Shops” we were founded on the idea of being a Neighborhood Jeweler. That means you meet your jeweler, talk to a jeweler and consult with a jeweler. Build a relationship.

​We know buying jewelry can be an intimidating purchase, but we’re here to answer your questions, educate you when/where you want to be and to grow that relationship. Unlike many other jewelers we know that building a meaningful trust benefits both of us in the long-run.

Engagement / Weddings

From start to finish our jewelers are here to help you along with a well trained staff… Not a sales rep with bare knowledge and a singular goal.

We can sit down with you (make an appointment if you’d like); discuss her tastes and sketch out or select the perfect engagement or wedding ring to match for your special someone, find you the stone to fit your budget and guide you through it all. The next steps are even easier!

We can print a 3d model or wax of your custom ring, make alterations if necessary, cast the ring and most importantly it’s all done in-house.

From start to finish we are the ones designing, casting, setting and finishing your ring. Cutting out a lot of the middle men saves time and money.

We also carry a large selection of modern Men’s rings and make exceptional traditional gold & platinum bands as well.

Call us or stop in, shake our hand. No obligations! And please, check out our ever-growing portfolio and online reviews.

We have partnered with Thorsten Jewelry for cutting-edge wedding bands for men and women. Check out their rings here.

The 4C's of Diamonds

When shopping for diamonds, it’s essential to understand the 4Cs: Cut, Color, Clarity, and Carat Weight. These factors determine a diamond’s quality and value, and our knowledgeable staff is here to help you navigate these characteristics to find the perfect diamond.

The cut of a diamond refers to its proportions, symmetry, and polish. A well-cut diamond will reflect light beautifully, creating a brilliant sparkle. At Cornerstone, we offer diamonds in a range of cuts, including:


Diamond color is graded on a scale from D (colorless) to Z (light yellow or brown). While truly colorless diamonds are rare and expensive, diamonds in the near-colorless range (G-J) offer excellent value and appear white to the untrained eye.


Clarity refers to the presence or absence of inclusions (internal flaws) and blemishes (external flaws) in a diamond. Clarity is graded on a scale from Flawless (FL) to Included (I1, I2, I3). Most diamonds fall in the SI (Slightly Included) or VS (Very Slightly Included) range, offering a great balance of beauty and value.

Carat Weight

A diamond's carat weight measures its size. One carat equals 0.2 grams, and diamonds are often sold in 0.25-carat increments. Keep in mind that a diamond's value is determined by all four Cs, not just carat weight.
