2.11ct Heart Shaped Blue Lab-Grown Diamond | Fancy Vivid Blue | IGI

Diamond clarity is a key indicator for assessing the internal and external imperfections of a diamond. We use international standard clarity grades, including FL (Flawless), IF (Internally Flawless), VVS (Very, Very Slightly Included), VS (Very Slightly Included), SI (Slightly Included), and I (Included). The higher the clarity grade, the fewer imperfections the diamond has, and usually, the higher the price. Mount Tisé offers diamonds with clarity grades ranging from SI1 to VVS1:

• VVS1 (Very, Very Slightly Included, First Grade) - Contains very few minute inclusions, nearly invisible to the naked eye.
• VVS2 (Very, Very Slightly Included, Second Grade) - Contains very few minute inclusions, difficult to detect even under 10x magnification.
• VS1 (Very Slightly Included, First Grade) - Contains very few inclusions, still difficult to see under 10x magnification.
• VS2 (Very Slightly Included, Second Grade) - Contains minor inclusions, hard to see with the naked eye.
• SI1 (Slightly Included, First Grade) - Contains visible inclusions, but with no significant impact on overall appearance.

After being set in jewelry, the diamond's light transmission may be somewhat affected, making it hard to distinguish between extremely high clarity and high clarity. For setting and daily wear, we recommend diamonds between SI1 and VS1, as they look similar to higher clarity grades to the naked eye and offer better value for money.

The colour grading of fancy coloured diamonds is evaluated based on the vividness and rarity of their colours, which differs from the D to Z grading system used for white diamonds. Coloured diamonds come in a range of hues, such as yellow, blue, pink, green, and more, each with its own grading scale. The colour grades of coloured diamonds are assessed based on their vividness and saturation, ranging from light to deep, categorized as Faint, Very Light, Light, Fancy Light, Fancy, Fancy Dark, Fancy Intense, Fancy Vivid, Fancy Deep, and Fancy Dark. Mount Tisé offers coloured diamonds in various colours and grades:

• Faint - Light-coloured diamonds, showcasing a slight tint of colour.
• Very Light and Light - Display clear but subtle colours, suitable for those seeking unique but not overly vivid hues.
• Fancy Light - Light-coloured diamonds with noticeable hues, adding a tint to the jewelry.
• Fancy - Bright and vivid colours, relatively more obtainable among coloured diamonds, perfect for individuals seeking personality in their jewelry.
• Fancy Intense, Fancy Vivid - High saturation and vivid colours, representing the rarest and most valuable grades among coloured diamonds.
• Fancy Deep, Fancy Dark - Deep-coloured diamonds with extremely rich hues, offering unparalleled charm and rarity.

The cut grade is a critical standard for evaluating the craftsmanship of a diamond. It measures the precision of the diamond's cut, its symmetry, and its ability to reflect light. High-quality cuts provide more fire and brilliance, determining the beauty of the diamond's appearance. Cut grades range from highest to lowest as follows: "Excellent," "Very Good," "Good," "Fair," and "Poor." Diamonds with higher cut grades are dazzling and possess optimal optical performance. Mount Tisé offers diamonds with cut grades from Excellent to Good:

• Excellent: Diamond cutting is extremely fine, with exceptional light reflection and sparkle.
• Very Good: Cutting is excellent, with outstanding light reflection and sparkle.
• Good: Cutting quality is good, with commendable light reflection and sparkle.

Cut grades mainly apply to round-cut diamonds. For fancy-shaped diamonds (such as oval, princess, heart, emerald, etc.), there are usually no explicit cut grades. This is because different shapes of diamonds need to be evaluated based on their unique characteristics and cutting styles.
