The document provides a comprehensive guide on diamond grading, care, and valuation, covering clarity, color, cut, carat weight, and maintenance tips.

Diamond Clarity and Grading Scale

• Diamonds are graded under 10X magnification based on internal inclusions and external blemishes.
• The scale ranges from Flawless (FL) to Imperfect (I3), with most diamonds having some inclusions.
• Flawless and Internally Flawless diamonds have no visible inclusions under 10X.
• Slight and very slight inclusions can lower clarity grade but have minimal impact on beauty.

Diamond Color Grading and Rarity

• Diamonds are graded on a D-Z scale from colorless to faint yellow or brown.
• Higher grades (D-F) are nearly colorless, while lower grades show more noticeable hue.
• Fancy-color diamonds like pink or green are graded on a different scale and are rare and valuable.

Carat Weight and Size Representation

• Carat measures the weight of a diamond, with 1 carat equal to 200 milligrams.
• Larger carat weights are not always more valuable; cut, clarity, and color also influence value.
• The size of diamonds at various carat weights is illustrated but can vary in appearance.

Diamond Cut and Its Impact on Brilliance

• Cut refers to the proportions, symmetry, and polish of a diamond’s facets.
• Proper cut maximizes light reflection, brilliance, and fire.
• Poorly cut diamonds are too shallow or too deep, causing loss of brilliance and dullness.

Diamond Care and Maintenance

• Clean diamonds with a mixture of ammonia and water using a soft brush.
• Professional cleaning and prong checks are recommended annually.
• Store diamonds separately in soft pouches to prevent scratches.
• Avoid exposure to household chemicals, hair spray, and chlorine to maintain sparkle.
