Sparkle Guarantee


Arthur's Jewelers is the only jeweler to give you a Sparkle Guarantee.

The GemEx BrillianceScope measures the light return and the sparkle score of each of our diamonds. Every one of Arthur's thousands of diamonds comes with a Sparkle Guarantee, verified with the GemEx Light Performance Analysis. This lab report verifies the light performance and the sparkle score of your diamond.

We give you the sparkle score so you know immediately which diamond gives you more sparkle for your money. With the sparkle score, a novice can easily pick out the best diamond each and every time!

No other jeweler can provide you with the proof of sparkle that Arthur's can. Every diamond has their own unique identity or sparkle score. Above and beyond the 4C's, each diamond has a distinctive visual brilliance pattern. This is the Sparkle Factor. Arthur's Jewelers can prove why our diamonds have more brilliance, fire, and sparkle. Arthur's Jewelers will review the GemEx report with you and demonstrate the sparkle, or light return, right before your eyes.

The GemEx Diamond Light Performance Certificate
is the most important certificate to accompany your diamond.

No other store in the Twin Cities has this proof of sparkle.

This Light Performance Analysis report can take 100 diamonds of the same size, color and clarity, then rank them on light return or Sparkle. The higher the ranking, the more Sparkle. Sparkle is what she's looking for in an Engagement Ring...it's what she'll see when she puts it on her finger!

Other jewelers don't show you the sparkle score of your diamond because it will show, verify and prove that the diamonds they're selling are of lower quality and don't have much sparkle - no matter how they describe the cut of their diamonds. Anyone can use fancy adjectives, but facts are facts. At Arthur's, we feel you deserve all of the facts about your diamond.
