Lifetime Diamond Guarantee & Warranty

DIAMOND WARRANTY

Ada's diamonds are the hardest substance on earth — ten times harder than a Sapphire or Ruby. A 10 out of 10 on the Mohs hardness scale, Ada diamonds are extraordinarily resistant to heat, chemicals, and scratching. Furthermore, lab grown diamonds are less likely to chip than mined diamonds since they have less strain, defects, and impurities in their crystal structure.

Because of their quality, we guarantee that diamonds purchased from Ada will not fade, cloud, change color, or lose their brilliance in your lifetime.  If, at any time, your Ada diamond loses its optical quality after purchase, your diamond will be eligible for trade-in for a diamond of comparable size and quality. There is no additional fee for this warranty. Ada Diamonds reserves the right to waive this warranty with advanced pre-payment warning to a client for any commissioned stones cut to specifications not recommended by Ada Diamonds (such as stones too narrow or too shallow for quality fabrication). 

JEWELRY WARRANTY

Ada Diamonds is proud to offer a warranty on its jewelry. Within the first two years of purchase, we will replace side or accent diamonds (of 0.25ct and smaller) that go missing if due to a manufacturing defect. Our warranty excludes coverage due to wear and tear and/or negligence. Any repairs or work not done by Ada Diamonds or authorized third parties we work with will void this warranty. We cannot stress enough the importance in choosing jewelry that is appropriate for your lifestyle. Ada Diamonds does not guarantee replacement for a center stone lost by impact to the jewelry, and strongly encourages our clients to obtain jewelry insurance in the event of extreme damage, loss, or theft.

CLEANING AND MAINTENANCE

SF Bay Area residents are welcome to drop off Ada Diamonds jewelry for cleaning and polishing at our Sunnyvale or San Francisco locations. Same day service may be available. Re-plating of rhodium carries a $50 service fee and is recommended every few years for 14kt and 18kt white gold jewelry. 

For those outside of the bay area, Ada offers cleaning and polishing for $50 and re-plating for $100. These fees cover the cost of fully insured shipping both ways
