Product Authentication

Authenticity Guarantee

We understand that Authenticity is of the most concern when purchasing a product from an online store. When you purchase from rest assured that:

All of our products are 100% Authentic, Original & Brand New.

You are shopping at an established, reputable store that has been in business for 36 years.


It's important to trust the gemologist that you're buying the products from.  But it's also helpful to have certificate of authenticity from the company that you're buying from as well.  And as an added level of security, you may want to obtain a certificate from an accredited independent laboratory, especially if you're buying a higher value gemstone.  Our certificates would provide substantiation and specified details about the product such as its cut, shape, weight, measurement, and color with an image (upon request) of the product that would be supplied to you evidencing its authenticity.

Below are the certificates that are available to you to verify our finely made Gemstones and Diamonds:

  • Gemstone Lab certification issued by the trusted Laboratories.
  • certification issued by the confidential gemstone professionals.

The certificates can be provided on request with every good purchased from Semipreciousking with a certification cost authorizing our products and services.
