We started in 1972 as Lochs, helping clients worldwide obtain uncut and cut gemstones. We specialize in engagement rings and other Diamond jewelry featuring Diamonds hand selected in Antwerp, Belgium by our Certified Diamond Grader.

Each Diamond over 1/2ct. is graded to standards exceeding those used by outside labs such as GIA, AGS, and HRD. More importantly our Diamonds are graded for Light Performance which is a more accurate way of measuring how the Diamond cutter transformed the rough crystal into a scintillating ball of fire. Light performance is the most important factor affecting a diamonds beauty and value, by as much as 40%.

We value knowledge and integrity which assures you that your Diamond has been accurately graded and evaluated by the Lehigh Valley region’s only Certified Diamond Grader, and Master IJO Jeweler working in the only Certified Gem Lab in the region. Unlike the outside Labs we stand behind our grading 100%. When you read their fine print, you will see that they take no liability for their grading. That has never been good enough for us at Eric J. Loch Diamonds & Fine Jewelry.
