Crafted and Curated with 130 Years of Experience

What Sets Our Approach Apart

At Johantgen Jewelers, we believe buying diamond jewelry should be clear and enjoyable. Our approach is rooted in education, transparency, and experience.

Seeing the Difference

Certificates and grading reports are helpful, but they don’t show how a diamond looks in real life. We take the time to show stones side by side and explain how light, cut, and proportions affect appearance. This helps you understand what you’re choosing and why it matters.

Fair, Transparent Pricing

Our pricing reflects quality and craftsmanship, with clear and consistent margins. We focus on long-term value, which is why many families return to us generation after generation.

Built to Last

Every piece is carefully inspected for durability and everyday wear. We check settings, prongs, and overall construction to ensure your jewelry remains secure and beautiful for years to come.

Types of Diamond Jewelry We Carry

Whether you’re treating yourself, celebrating a milestone, or finding the perfect gift, we have diamond pieces that fit:

1. Diamond Necklaces and Pendants

From classic solitaire pendants to elegant diamond drops, necklaces are versatile pieces you’ll reach for constantly. A quality diamond pendant works with everything from casual wear to evening attire. We carry various styles and diamond sizes, and we can help you choose a piece that flatters your neckline and fits your lifestyle. These make wonderful gifts because they’re personal without requiring ring sizing.

2. Diamond Earrings

Studs, drops, hoops, and huggies. Diamond earrings frame your face and add sparkle to every outfit. We pay attention to the details that matter: secure backs, comfortable weight for all-day wear, and settings that let the diamonds shine. Our stud earrings are particularly popular because they’re timeless, wearable every day, and never go out of style.

3. Diamond Bracelets

Tennis bracelets, bangles, and delicate diamond chains. A diamond bracelet catches light with every movement, making it one of the most dynamic pieces you can wear. We focus on bracelets with secure clasps, comfortable fits, and settings that protect the stones during daily wear. A well-made diamond bracelet becomes something you never take off.

4. Diamond Rings (Beyond Engagement)

Stackable bands, right-hand rings, anniversary bands, and fashion rings. Diamonds aren’t just for engagements. We carry diamond rings designed for everyday wear, special occasions, or adding sparkle to your existing collection. These make meaningful anniversary gifts or perfect personal purchases.

5. Loose Diamonds

Sometimes you want the diamond first and the setting later. We offer loose diamonds, both natural and lab-grown, so you can select your stone and then design the perfect piece around it. This approach works well for custom projects, upgrading existing jewelry, or choosing your diamond with complete focus before deciding on the setting.

6. Lab-Grown Diamond Jewelry

Real diamonds, different origins. Lab-grown diamonds offer the same beauty, hardness, and brilliance as natural diamonds at a significantly lower price point. We carry lab-grown options across all our jewelry categories. We’ll explain the differences honestly so you can decide what matters most to you.

How We Help You Find Diamond Jewelry You’ll Love Forever

Step 1: Understanding What You’re Looking For

We start with a conversation. What’s the occasion? Who’s wearing it? What’s your budget? Do you have style preferences? We ask questions because the right piece depends on your answers.

Step 2: We Take the Time to Explain

We explain what actually matters for the piece you’re considering. For earrings, we’ll discuss why cut quality impacts sparkle more than carat weight. For pendants, we’ll show you how setting style affects how the diamond catches light. We use real diamonds to demonstrate differences.

Step 3: Showing You Real Options

We bring out pieces that match your criteria and let you see them, touch them, and try them on. Diamonds look different in cases than they do on your body. We give you time to compare, ask questions, and think.

Step 4: Honest Conversation About Value

We’ll tell you what you’re paying for and why. If a piece is priced higher, we explain what makes it worth more. We’d rather sell you the right piece at the right price than push you toward something that doesn’t make sense.

Step 5: Quality You Can Trust

Every piece we sell meets our standards for construction and durability. We inspect settings, check prongs, and verify that the jewelry is built to last.

Step 6: After the Purchase

We’re here for cleaning, inspections, and any questions that come up later. Our relationship doesn’t end at the register.
