Gemstone Identification and Grading.
All gemstones are graded and evaluated in their settings, unless otherwise stated in the listing. Since it is not possible to provide exact color, clarity, and weight of mounted gemstones, all data pertaining to mounted gemstones should be considered approximate unless accompanied by an independent laboratory certificate (GIA, AGL, or EGL). Additionally, unless accompanied by an independent laboratory certificate, all color gemstones and pearls should be assumed to be subject to possibly undetected color or clarity enhancement.
Our reputation is extremely important to us and we stand behind every item we sell with a full money back guarantee. If you have questions or concerns about the authenticity of any item purchased from our store, we will be happy to address your concerns and work on a resolution or refund.
