Diamond Mansion takes pride in offering you only the highest-quality natural, Earth-mind,  untreated diamonds. All our diamonds are certified by independent gemological laboratories like the Gemological Institute of America (GIA). Upon purchase, you'll receive a certificate of authenticity and quality report unique to your diamond.

Diamond Mansion only sells conflict-free diamonds. We adhere to strict guidelines set by the Kimberley Process, an international process established in 2003 to prevent “conflict diamonds” from entering the market. Per the process, all diamonds entering the United States and other participating countries must be accompanied by a government-issued Kimberley Process Certificate. We source our diamonds only from the most respected suppliers, who comply with all Kimberley Process standards. For more information about the Kimberley Process, please visit KimberleyProcess.com.

Diamond Mansion offers a 30-day full money back guarantee, no questions asked. As long as the item is returned in its original condition within the return policy period, we provide a full refund and won’t charge a restocking fee.*

*Customer is responsible for return shipping.

We handcraft our products with care and precision, ensuring they’ll withstand the test of time. Diamond Mansion’s lifetime warranty covers damages and defects during normal, everyday wear for the lifetime of the ring.

In the rare case that your jewelry does have a manufacturing defect, we’ll either repair or replace the jewelry free of charge.

Be aware that all types of fine jewelry, especially rings, are vulnerable to wear caused by daily activities. Diamond Mansion’s lifetime warranty does not cover lost, stolen, cracked, or chipped diamonds. It also does not cover damage resulting from neglect and avoidance of necessary repairs. Though not a conclusive list, the following examples would not be considered manufacturing defects:

1. Normal wearing away or bending of prongs, which can occur from daily use of hands or from accidental bumping of hands against another object
2. Loss or chipping of stone(s) due to daily wear
3. Discoloration of metals due to reaction with body chemistry, exposure to household or other chemicals, or improper storage of jewelry

In addition, resizing or repair work performed by a jeweler other than Diamond Mansion will void the lifetime warranty.

To protect your diamonds from damage, loss, or theft, we recommend jewelry insurance Jewelers Mutual.

Diamond Mansion promises lifetime upgrades on all GIA-certified diamonds originally purchased from us. When upgrading, you have two options: 1) you can upgrade only your diamond or 2) you can upgrade both your diamond and setting, depending on whether or not the setting is reusable and can accommodate your new stone:

• We’ll give you 100% of your original purchase price toward a new diamond.
• The new diamond must cost 40% more than what you paid for your original diamond.
• Your diamond must be in its original condition and include its corresponding certificate.

• If you’d like your new diamond set in your old setting, the old setting must be in reusable condition, and it must be able to accommodate the size of the new diamond. As long as you meet these two requirements, we’ll set the new stone in your old setting free of charge.
• If the setting is not reusable, we’ll help you find or design a new setting to fit your upgraded diamond. The customer is responsible for any charges related to the new setting.

Diamond Mansion recommends sending us your jewelry or bringing it to our Los Angeles showroom for cleaning, polishing, and inspection every six months. Routine cleaning and inspection ensures that no diamonds are loose and that the prongs are strong.

To help you keep your jewelry looking like the day you bought it, we offer lifetime maintenance free of charge. Lifetime maintenance includes:

• Polishing
• Rhodium plating
• Deep cleaning
• Resizing up to two sizes
• Tightening loose stones
