Quality Assurance HEADING_TITLE

We adhere to a very strict set of quality assurance standards for selecting the jewelry and diamonds that we offer to our customers. In accordance with these standards, every piece of jewelry that we offer must conform to our rigorous and stringent requirements for overall quality.

Each item will be inspected in its entirety, i.e. quality of diamond(s) and/or stone(s), quality of mounting, precious metal content, stamping and tagging. Diamonds shall be graded for clarity and color based upon the Gemological Institute of America's (GIA's) diamond grading system.

List of Diamond & Jewelry standards inspected:

  1. No knife-edge girdles or extremely thick girdles in the diamond.
  2. No dark centers in the diamond which are the result of light leakage caused by too deep of a pavilion.
  3. Round diamonds must have a table percentage between 52% and 67%.
  4. Round diamonds must have crown angles no less than 30 degrees or greater than 38 degrees.
  5. Diamonds must be good or better symmetry and polish.
  6. No chips, breaks or fractures in the stone.
  7. No laser drilled diamonds.
  8. No treated (clarity enhanced) diamonds including fracture filled treatment.
  9. No diamonds will have strong fluorescence.
  10. Culet size on diamond must be None - Medium.
  11. On all items containing more than one diamond, the diamonds shall face up approximately the same size and color.
  12. Diamonds must be properly seated, securely set and not loose.
