I·de·al n. 1. A conception of something in its absolute perfection. 2. One that is regarded as a standard or model of perfection or excellence.

An Ideally proportioned stone will have tremendous brilliance and scintillation. An ideally cut diamond will not be cut to retain weight or appear larger than it is. The only goal in cutting an ideal cut diamond is to maximize the brilliance, fire, sparkle and beauty of the diamond.

Of the many independent labs available, only the American Gem Society Lab grades diamonds for the accuracy of their cut. Many labs claim there is no range of proportions that are more brilliant than others or make their parameters so loose that just about any diamond can be called Ideal.

At Vivo Diamonds, we trust only the AGS Lab to grade our diamonds as Ideal Cut. An AGS Diamond Quality Document (DQD), showing the stone to have achieved Ideal specifications for Polish, Symmetry, Proportion and Light Performance (in the new AGSL documents) accompanies every Vivo Signature Diamond.

Every facet in an AGS Ideal Cut diamond must be placed at precise angles and has precise proportions. This ensures an Ideal balance between maximum brilliance and dispersion of light. Any discrepancy from these proportions will disrupt the even distribution and dispersion of light within the stone, and will result in a loss of beauty.

Why aren't all diamonds cut to Ideal Proportions?

The answer is one of simple economics. It takes longer and more technology to cut an Ideal Cut. The process is assisted by computer and laser analysis. Only very experienced cutters can achieve this level of excellence, and, unfortunately, there is a greater weight loss of the original rough diamond. All of these factors contribute to the rarity and cost of Ideal Cut diamonds.

Beware of "GIA Ideal Cuts"

The GIA specifically claims that there are no sets of proportions that are "Ideal." We obviously disagrees. Jewellers that try to sell you an Ideal Cut with a GIA report are relying on your lack of knowledge. Any diamond with a decent depth and a small table is not necessarily an Ideal Cut. If you are in search of a true Ideal Cut diamond and do not have an AGS report, insist on full disclosure of all the aspects of the diamond's proportions. A Sarin or MegaScope report will give you a breakdown of all the angles (missing in the GIA report). Also insist on seeing pictures of the Hearts and Arrows or at the very least a BrilliantScope report to make sure you are getting a great performing diamond.

Vivo Signature Diamonds

We cherry picked every single signature diamonds with a set of strict parameters. The parameters we used are stricter than traditional AGS proportions. Round brilliant diamonds within this range of measurements receive the highest ratings in both proportions and performance grading systems.
