For Retailers

Here are some ways you could use our services:

Concerned about not easily recognized beryllum-diffused and lattice-diffused sapphires and rubies? We can tell you they are alive and well and they have made their way to Columbus, OH. They're just not in Thailand any more. We keep up on the latest news and education in regards to detecting synthetics and simulants. Call us to gain piece of mind.

Interested in increasing revenue by offering an appraisal event in your store? We have a completely mobile gem lab and will travel. We can entirely appraise a piece and prepare the appraisal while your customer waits.

Not interested in an appraisal event but want to offer your customers appraisal services? Call us directly and we'll offer some suggestions on how we can help you.

Do you have diamonds that would sell better if they came with diamond certificates? Let us help you out with that. Call us for details.
