Do you know what your jewelry is currently worth?

An appraisal provides important information about your jewelry, including its materials, identifying characteristics and estimated replacement value. This documentation may be needed when discussing insurance coverage, managing an estate or simply creating an accurate record of the pieces you own.

Because precious-metal, gemstone and replacement costs can change, an appraisal from years ago may no longer reflect today’s market.

Gruno’s Diamonds offers professional jewelry-appraisal services to help you better understand and document your collection.

Contact us to learn more or arrange an appraisal.

This is one of @‌Rolex's diamond-paved dials. Adorned with hundreds of meticulously chosen diamonds. Tiny holes are first drilled into the gold disc to cradle the precious stones. In a precisely orchestrated sequence, the gem-setter places each diamond before folding a delicate sliver of metal over its edge to hold it in place. These gold fragments are then shaped and polished into minuscule, radiant domes. It is a process every Rolex artisan can replicate, time and again. From this shared mastery, a dial of perfect harmony, whose sparkle never compromises the clarity of time.

What gives a diamond its sparkle?

Many people assume a larger diamond will automatically sparkle more, but size is not the deciding factor. Much of a diamond’s beauty comes from how effectively it handles light.

The diamond’s cut—including its proportions, symmetry and polish—influences how light enters the stone and returns to your eye. A well-cut diamond can appear bright, lively and full of movement.

Cleanliness matters, too. Lotion, soap and oils can leave buildup on the surface and beneath the stone, reducing its sparkle.
When comparing diamonds, look beyond carat weight. The quality of the cut and the overall appearance of the stone can make an extraordinary difference.

Visit Gruno’s Diamonds to compare diamonds in person and see the difference for yourself.

We invite you to shop Tudor with us at our Madison location.

A fine watch is designed to last—but it still needs knowledgeable care.

If your watch is losing time, gaining time, stopping unexpectedly or showing signs of wear, Gruno’s Diamonds can help. Our watch-repair services are available for both routine maintenance and concerns that require a closer look.

Even when a watch appears to be running properly, its movement, seals and other components may need periodic professional attention.

Bring your timepiece to Gruno’s and let our team help keep it performing—and looking—its best.

Meet Elena! ✨

With almost three years in the jewelry business, she loves the people, the beautiful pieces, and the meaningful moments she gets to be part of at Gruno’s Diamonds.

Her favorite part? Seeing a customer’s excitement when everything comes together—and knowing she helped make that moment happen.

Ask her to choose between engagement rings and watches, and her answer might change daily! She loves the little details that make a ring right for a couple, but helping someone find a watch they’ve dreamed of owning is just as special.

One thing Elena does like to know in advance? How a movie ends. 🎬 If her commentary suddenly stops during movie night, her husband knows she’s Googled the ending! Lighthearted movies—or a few spoilers—are her preference. 😉

Say hello to Elena in the comments, and let us know if you have had the pleasure of working with Elena!
