A night and day transformation. This diamond necklace appears uniformly dazzling under daylight. Under UV light, however, it reveals a striking transformation. Featuring both inert and fluorescent diamonds, it showcases a range of blue fluorescence intensities.

The desirability of fluorescence has long been debated, but as interest in more distinctive, character-rich gems grow, diamond fluorescence is gaining new appreciation.

Rigorous GIA research shows that for the vast majority of diamonds, fluorescence has a positive impact on appearance and can actually make a diamond appear brighter in natural light.

Emeralds have captivated people for thousands of years. Some of the earliest known mines were in ancient Egypt, where emeralds were extracted from the Eastern Desert during the time of Cleopatra.

Today, the world’s most famous emeralds come from Colombia, where mines such as Muzo, Chivor and Coscuez produce gems prized for their strong green to bluish green color. Brazil is another important source, producing emeralds in a range of shades. In Africa, Zambia has become a major producer, known for stones that are often darker with a subtle bluish hue modifier.

Other notable deposits occur in Pakistan and Afghanistan, which can produce saturated crystals, as well as Ethiopia, Zimbabwe and Madagascar.

Even the United States has produced emeralds. Deposits discovered in North Carolina in the 1800s still occasionally yield emerald crystals—showing that this remarkable green gem truly has a global story.

What happens when leading gemologists encounter a stone they don't recognize?

Dr. Aaron Palke, Senior Manager of Colored Stone Research, shares the story of an unidentifiable mineral that led to the discovery of a new species.

A dealer submitted this specimen, and it was unlike anything the team had seen before. Advanced testing by GIA's research team confirmed this was a special discovery. This member of the beryl family remains extremely rare today.

What's the rarest gemstone you've ever seen?

Your emerald goes through rigorous, multi-step testing when it is submitted to a GIA laboratory. Here’s a peek into how our expertly-trained gemologists conduct their analysis for an emerald origin report:

1. General Observation: Shape, transparency and carat weight are recorded. Green color confirmed with Munsell chips.

2. Standard Gemological Testing:
- Measure Specific Gravity
- Refractive index: Determine how much the gem bends light when light is moving through it (emerald= 1.579-1.589).
- Handheld Spectroscope: Check for chromium-related features that are visible in emerald.

3. Analytical Testing:
- LA-ICP-MS: Advanced instrument reveals trace element chemistry, which helps determine geographic origin.
- UV-Vis-NIR: Advanced instrument measures how light interacts with the gem, which is related to chemical composition.

4. Microscopic Examination: Inclusions help determine geographic origin and potential treatments, including clarity enhancement.

5. Report: Report is reviewed and issued. Determination of clarity enhancement and filler type (when requested) is specified within the report.

GIA colored stone reports are based on decades of expert laboratory and field gemology research.

This Burmese ruby and diamond necklace holds a secret—revealed only under ultraviolet light. As the UV lamp passes over the piece, the rubies glow vivid red, while some of the diamonds glow blue.

The rubies’ intense fluorescence comes from chromium—the same element that gives them their rich color. Formed in marble deposits, Burmese rubies contain very little iron. Since iron can suppress fluorescence, its absence allows the stones to fluoresce with remarkable intensity, enhancing the gems’ red color even under daylight and increasing their value.

Diamonds fluoresce for an entirely different reason. Most diamonds contain trace amounts of nitrogen within their crystal structure. Under certain conditions, these nitrogen atoms can absorb UV energy and emit a soft blue light.

The beryl family is packed with gem-world celebrities including emerald, aquamarine and morganite. Then there’s the rare and mysterious maxixe beryl and red beryl, plus more common beauties like heliodor, goshenite and green beryl.

Beryl is allochromatic, meaning it's colorless in its purest form. It gets its color from trace elements or radiation.

- Green beryl gets its pale green hue from iron.
- Emerald glows green thanks to chromium and vanadium.
- Aquamarine gets its serene blue hue from iron.
- Maxixe turns deep blue from radiation, but its color can fade!
- Red Beryl owes its rich red hue to manganese.
- Morganite blushes pink from manganese.
- Goshenite is pure, colorless beryl, sometimes with trace elements but not enough to add color.
- Heliodor’s golden yellow comes from iron.

Which beryl variety is your favorite?
