Diamond Certification

Glitter Jewels are graded by the industry's most stringent diamond grading labs: AGSL and GIA. Each diamond available from Glitter comes with either a diamond grading report, diamond dossierĀ®, or a diamond quality document.

The certified diamond experts at these diamond grading labs observe the diamond with their own expert eyes, as well as with a number of scientific tools to document the dimensions, color, clarity and carat weight of the diamond.

Diamond Grading Reports

Yellow gold offers a warm glow, and even white gold is a warmer white than metals like platinum or palladium. Pure gold is too soft to hold its shape in fine jewelry, so it's alloyed with other precious metals for strength. Look for "14k" or "18k" as a fineness mark that proves the quality of your gold jewelry. Among fine metals, gold tends to be more malleable, so prongs in a gold engagement ring should be checked each year with one of our Free In-Store Preview jewelers, and they can also re-plate white gold with Rhodium to bring it back to its original whiteness. To know what she'd prefer in an engagement ring, check the color of the metal jewelry she wears. If you choose a yellow gold ring, the color of the metal can make a near-colorless diamond and a colorless diamond look the same.
