What are calibrated diamonds and how can you get them ?

Only with a closer look or under a magnifying lens, one might be able to see the difference in the shapes of the diamond. Given the situation, it is tricky for to jewelers create multi-stone designs that appear consistent, dazzling, and unique.

Prospective clients are often demanding and may request to fit diamonds in desired sized setting. This can be challenging due to the size tolerance of calibrated stones, which one should consider while shopping for supplies.

Things to consider before buying calibrated diamonds

• Estimations: This plays an important role when designing ornaments with multi-stone settings. To the naked eye, the setting of these stones should appear equal. There can be minimal variations, but the setting should be even, making millimeter sizes a state of mind.
• Shading: When choosing synchronized precious stones, color characteristics should be considered. If ornaments are set in different tones, it is imperative for adjusted precious stones to be in sync. For a uniform setting, dull or tame precious stones cannot be combined with a yellow or earthy color stones.
• Lucidity: This trademark refers to the interior and exterior flaws visible in calibrated diamonds when magnified by 10X. To ensure quality consistency, aligned ornaments should always be chosen with this trademark only.
• Shape: Jewelers choose calibrated diamonds based on their shape and appearance. E.g.: Round-cut precious stones are combined or paired with other round-cut precious stones to give the desired look. If multiple shapes are used in settings, ornaments can be coordinated together by using shading techniques and quality components.

Calibrated diamonds sizes

The diamond size should not be the same as the setting size. The setting of the jewelry can be modified based on the range of jewel sizes. In a standard setting, any round stone can fit as desired. Even then, there are various components to consider when considering different shapes.

Ornaments weighing less than one carat should be accommodated with 0.1 mm of the setting size. Diamonds weighing more than one carat can be accommodated with a 0.2 mm difference, and sometimes even more.
