Since 1991, Diamonds by Monet has been Temecula’s trusted, family-owned jeweler. We specialize in custom engagement rings, fine jewelry, and expert in-house repairs. We believe in lasting relationships, not just sales—guiding and educating you through every step

Yes, we carry both natural and IGI/GIA-certified lab-grown diamonds in a variety of shapes, sizes, and price ranges.

The choice between a lab-grown and a natural diamond comes down to your personal preferences, values, and budget. Lab-grown diamonds are real diamonds with the same chemical and physical properties as natural ones, often offering larger sizes or higher quality at a lower price. Natural diamonds are formed over billions of years in the earth and are prized for their rarity and timeless tradition.

At Diamonds by Monet, we believe in education, not judgment. Our role is to guide you through the differences, explain the benefits of each option, and help you make an informed decision that feels right for you. Whether you choose lab or natural, we work with your budget and prioritize craftsmanship to ensure your piece is something you’ll cherish for a lifetime.

Taking off jewelry before using cleaning supplies, harsh chemicals, hand sanitizer, or lotions, since they can cause discoloration, buildup, or loosen stones over time.

Professional cleanings and prong checks every 4-6 months or if hit at anytime. Stop by anytime we offer free steam cleaning and prong inspection.

At home, you can gently clean most jewelry using warm water, mild dish soap, and a soft toothbrush to remove dirt and oils. Rinse thoroughly and dry with a soft, lint-free cloth.
