MILANJ Price Match Guarantee

At MILANJ Diamonds, we are committed to offering you the most competitive prices on lab grown diamonds. If you find a comparable loose lab grown diamond from another U.S. retailer at a lower price, we’ll match it—guaranteed.

To qualify, the diamond must match ours in carat, cut, color, clarity, and shape, and be available for purchase on a public retail website (not a private seller or auction). Price Match applies to loose diamonds only, not finished or custom jewelry, as craftsmanship and materials vary between jewelers.

Simply email us with the link to the competitor’s diamond before you complete your purchase. Our team will verify the match within 1–2 business days and provide you with a custom discount code if approved.

At MILANJ, you get the best price, expert service, and the confidence of shopping with a trusted jeweler.
