Your engagement diamond will last as long as your love, and so will our support. We put it in writing: we call it our 110% Lifetime Diamond Warranty.

A lifetime of loving your engagement diamond. We’re all committed to that. We are so confident in our engagement diamond’s quality that we will replace it for up to 110% of the original purchase price, for a lifetime.

110% Diamond Sparkle Guarantee

Our engagement diamonds shine and sparkle brighter. Just like your love…

At Robbins Brothers we take great care and pride in hand selecting our engagement diamonds for visual beauty. We have the utmost confidence in the beauty and quality of every engagement diamond we offer.

If within 30 days of your purchase, you find a more beautiful diamond with the same specifications at a lower price anywhere in the USA, bring the diamonds to Robbins Brothers. We will then send both diamonds to our corporate office to be graded for the three attributes of light performance: brilliance, sparkle and intensity.

We know you don’t want to be separated from your diamond, but it's the best way possible to provide an objective measurement for comparison. If your diamond scores higher, we will refund the Robbins Brothers engagement diamond or you can keep the Robbins Brothers engagement diamond and we will refund 110% of the difference between the purchase price of the two diamonds.
