The Aye & Co. goes above and beyond the current industry standards to offer diamonds that originate from pure, ethical sources. Our diamonds are traceable to their origins and demonstrate a robust chain of custody.

Our ethically sourced natural diamonds originate from mines that follow strict labor, trade, and environmental standards. Recycled diamonds are also an ethical choice, as they decrease the demand for new mining by repurposing diamonds from secondary sources.

A diamond certificate or grading report provides an expert opinion on the quality of the diamond and is provided by an independent gemology lab. Trained gemologists with specialized equipment measure the weight and dimensions of the diamond and assess quality characteristics such as cut, color, and clarity. The Aye & Co. diamonds are certified by the world’s leading gem grading labs including GIA, IGI, and GCAL. Diamonds graded by CDL (Canadian Diamond Laboratory) are evaluated by specialized equipment on premise. If the diamond lab certificate is not available online, please contact us to request an electronic copy.

Describes the finish of the facets of the diamond. Polish is graded from Ideal, Excellent, Very Good, Good, Fair, or Poor. Polish grades of Good or higher have the least effect on the brilliance of the diamond and are suitable for the finest quality jewelry. Certain gem labs, such as Gemscan, incorporate Polish into an overall cut grade.

Length-to-Width Ratio –The length-to-width ratio compares the length of a diamond to its width to show how elongated a fancy-shaped diamond appears when viewed from the top. Length-to-width ratio is a matter of personal preference with some individuals preferring a more elongated shape and others a more equal or square shape. The most popular length-to-width ratios for fancy shapes are below.

Ex. A princess-cut diamond that measures 5.05 mm long by 5.00mm has a length-to-width ratio of 1.01 (5.05/5.00), and will appear perfectly square.

Most popular length-to-width ratios:
Princess: 1.00-1.05
Radiant: 1.00-1.05
Asscher: 1.00-1.05
Cushion: 1.00-1.05
Heart: 0.90-1.10
Emerald: 1.30-1.40
Oval: 1.30-1.70
Pear: 1.45-1.75
Marquise: 1.75-2.30

Describes the alignment of the facets of the diamond. If facets are misaligned, the diamond may poorly reflect light. Symmetry is graded from Ideal / Excellent, Very Good, Good, Fair, or Poor. Symmetry grades of Good or higher have the least effect on the brilliance of the diamond and are suitable for the finest quality jewelry. Certain gem labs, such as Gemscan, incorporate Symmetry into an overall Cut grade.
