GIA & IGI Certified Diamonds

What GIA and IGI certification means when buying a diamond

A diamond grading report helps buyers compare stones with more confidence. Palermo Havana & Co. uses GIA and IGI diamond information to help clients understand what they are actually buying before choosing a center stone.

What GIA and IGI reports show

A grading report can document important diamond details such as carat weight, measurements, color, clarity, cut information, polish, symmetry, fluorescence, inscriptions, and the report number used to identify the stone.

Why the report matters

• It helps confirm the diamond details match the listing or quote.
• It makes comparison shopping easier across online and local sellers.
• It gives a clearer starting point for value, quality, and tradeoffs.
• It helps separate real diamond information from vague marketing language.

What a certificate does not guarantee by itself

A report is important, but it is not the whole buying decision. Two diamonds with similar grades can look different in real life. Proportions, face-up size, video performance, shape, eye-clean appearance, and setting compatibility still matter.

GIA vs IGI

GIA is widely known for natural diamond grading and is also used for lab-grown diamonds. IGI is very common in lab-grown diamonds and is widely used across the modern diamond market. The best choice depends on the diamond, the report details, the price, and the buyer's goals.

How Palermo Havana reviews a certificate

• We check the report number and basic identity details.
• We compare measurements, table, depth, polish, symmetry, and shape-specific proportions.
• We look for clarity or durability concerns that may not be obvious from the headline grade.
• We compare the quote against the full ring plan, not only the stone by itself.
• We explain the tradeoffs in plain language before you move forward.

Send a certificate before you buy

If you are looking at a GIA or IGI diamond from Blue Nile, Rare Carat, Brilliance, a local jeweler, or another online seller, send us the report number, link, price, photos, and video. We can help you understand whether the stone fits your budget, setting, and timeline.
