The Dia-Co Standard
Our Jewelers treat their craft as an art form - striving for perfection and never less. This is what makes us the ideal extension of your store - we care about our pieces as much as you care about your clients.

Made in House
Our jewelers understand the market and the quality standard. Making everything in-house allows us to turn around pieces both quickly (7-10 days) and at the highest standard.
