sushil agrawal Blog 0

Terra Connoisseur (Gemstones) — Vladyslav Yavorskyy

Quick facts: a modern, photography-forward volume celebrating natural, untreated gems; heavy on aesthetics and collector stories; features thousands of original gem photos. Popular among connoisseurs and collectors. Yavorskyy+1

Why it’s on the list: in a market where provenance and natural/untreated status matter, Terra Connoisseur blends photography with a collector’s eye. Vladyslav Yavorskyy is both a gem dealer and photographer; his books (Terra Spinel, Terra Garnet and Terra Connoisseur) are prized for studio-quality images and an educated, collector-first perspective. The book helps readers learn to spot exceptional cut and colour and to appreciate rarity at a glance. Yavorskyy+1

What you’ll learn: visual literacy for connoisseurs — what top-quality cut, colour and clarity look like; how collectors evaluate untreated stones.

Who should read it: collectors who value photography and provenance, jewellery editors, and marketers who want to present gems as investment-grade objects.

How to use it: use the images to build mood boards, marketing pages, client catalogs; pair it with a technical handbook when making purchase decisions. Gem-A Shop

Suggested blurb for your blog:
“Terra Connoisseur is a love letter to natural gems — perfect for anyone who buys into rarity, untreated stones and the aesthetics of connoisseurship.”

Gems Made by Man — Kurt Nassau

Quick facts: classic technical reference on synthetic gemstones and lab-grown materials; essential historical and scientific background on synthesis methods and identification. Originally published 1980, still cited in technical lists. Internet Archive+1

Why it’s on the list: understanding synthetics and simulants is essential for anyone testing or trading gems. Nassau’s book collects the science behind man-made gems in a readable format. Even when newer synthesis methods appear, Nassau’s explanations of principles (flux growth, hydrothermal, flame fusion, etc.) remain a foundation for lab testing and buyer education. GIA and academic references continue to list it in their core libraries. GIA

What you’ll learn: how synthetic gems are made, how they differ from natural stones at the microscopic and inclusion level, and which tests reliably distinguish them.

Who should read it: gemologists, lab technicians, students in gem labs, and serious buyers who want to avoid being misled.

How to use it: as your primer on synthetic detection — read it before relying on a single handheld tester, and keep it alongside microscopy diagnostics when inspecting stones. Internet Archive

Suggested blurb for your blog:
“Kurt Nassau’s Gems Made by Man explains the science behind synthetics in plain language — required reading if you work with or buy higher-value coloured stones.”

Handbook of Gem Identification / Liddicoat (GIA)

Quick facts: practical, concise identification guide prepared by the Gemological Institute of America (GIA). Often listed as Handbook of Gem Identification or Liddicoat’s handbook — it’s a perennial student text with charts and simple testing protocols. Internet Archive+1

Why it’s on the list: produced by the GIA, the handbook offers consistent, practical identification steps for dozens of gem species. It’s aimed at those learning gem testing and is regularly cited as a first step before advanced analytical work. The GIA library recommends it and includes it among essential student references. GIA

What you’ll learn: refractive index basics, specific gravity, pleochroism, simple polarizing microscope observations and straightforward testing workflows for many gem types.

Who should read it: gem students, junior lab technicians, independent appraisers and anyone who wants to perform confident, methodical ID checks.

How to use it: combine it with good tools (refractometer, polariscope, specific gravity kit) and treat it as the “how-to” companion to a visual guide. For deeper research, consult specialized monographs. Internet Archive

Suggested blurb for your blog:
“Liddicoat’s Handbook of Gem Identification is a practical, no-nonsense starter guide for anyone learning the tools of identification — highly recommended for students.”

Handbook of Gemmology — multi-volume (latest 5th edition, editors/compilers)

Quick facts: multi-volume technical manual, used by labs and institutions; covers advanced identification, grading and gem treatments. Recent updated editions (e.g., 5th edition releases in 2024–2025 cycle) modernize techniques and expand coverage of treatments and advanced instrumentation. I.DAVID+1

Why it’s on the list: for professional gemologists and laboratories, nothing beats a comprehensive multi-volume handbook that covers advanced spectrometry, inclusion analysis, and grading systems across many gem species. A newly updated fifth edition (recently announced in 2025 community posts) shows the field is evolving and the handbook remains central. gemologyonline.com

What you’ll learn: advanced instrumental techniques (spectroscopy, microscopy), grading protocols, treatment detection and species-specific forensic analysis.

Who should read it: professional gemologists, lab directors, serious educators and advanced students.

How to use it: keep within lab reach; use it as a citation source in expert reports and as a training manual for junior staff. New editions will reflect modern treatments and detection technology, so update your library accordingly. I.DAVID

Suggested blurb for your blog:
“The multi-volume Handbook of Gemmology is a lab staple — necessary if you’re doing advanced identification or writing formal gem reports.”

The Microworld of Diamonds — John I. Koivula (and similar diamond micro-photography works)

Quick facts: specialist work on diamond inclusions and microscopic features; essential when dealing with high-end diamonds, synthetics and treatments. Koivula’s microphotography has been seminal in diamond inclusion studies. GIA

Why it’s on the list: diamonds require separate, specialized study: the interplay of clarity, origin, and treatments (HPHT, CVD) means diamond-specific literature is essential. Koivula’s work and similar specialist volumes are prized for high-magnification photos and pattern recognition that help diagnose origin and treatment. GIA

What you’ll learn: how to interpret diamond inclusions, how to spot synthetic diamonds or diamonds altered by treatment, and what microstructures mean for origin claims.

Who should read it: diamond graders, appraisers, lab techs and high-value diamond buyers.

How to use it: use microphotographic plates when doing inclusion comparisons and cross-reference with the latest lab alerts for new synthetic diamonds and treatment markers. GIA

sushil agrawal Blog 0

Gemstones of the World — Walter Schumann

Quick facts: classic one-volume reference; richly photographed; recommended as an all-purpose handbook for hobbyists, makers and gem students. Editions updated across decades (5th edition widely used). GIA+1

Why it’s on the list: Schumann’s Gemstones of the World is the archetypal single-volume guide: compact enough to sit on a coffee table, thorough enough to use for field reference.

GIA’s library and many gem dealers still list it as a highly practical reference. GIA

What you’ll learn: identification basics, visual comparison (rough vs. cut), treatment overviews, how common gems differ by locality, and quick reference specs for scores of species.

Who should read it: beginners → intermediate collectors → bench jewellers who need a fast visual cross-check.

How to use it: use it as your day-to-day reference next to your loupe. When you encounter an unfamiliar stone in rough or cut form, flip to the relevant entry for a visual match, then consult a technical handbook for lab-level testing. Because it’s concise, pair it with one technical handbook on treatments or synthetic detection if you’re buying high value stones. Google Books

Suggested blurb for your blog:
“Schumann’s Gemstones of the World is a go-to identification and visual reference — ideal for gem lovers who want a single, accessible volume that covers the essentials without jargon.”

Who should read it: designers, jewellers who sell to retail clients, collectors building visually compelling presentations, and bloggers needing high-quality images and accessible copy.

How to use it: loan a copy to your showroom, use photos for inspiration (respecting copyright), and quote short factoids in client education — but always link buyers to technical sources for certification details. DK

Suggested blurb for your blog:
“DK’s Gem is a coffee-table gem for the modern jewellery lover: sumptuous images, clear captions, and bite-sized context make it a joy to read and a persuasive piece in any boutique.”

1.1Discovery in Early Civilizations

The name Iolite comes from the Greek word “ios,” meaning violet. Although the gemstone became famous during the Viking Age, its earliest usage traces back to Greek and Roman civilizations, where it was prized for its color and clarity.

These early cultures believed iolite symbolized:

2.1 Navigation Using Iolite

One of the most fascinating historical uses of iolite comes from the Vikings. These Nordic explorers used iolite as an early form of a polarizing filter to locate the sun’s position, even on cloudy days or when the sun was below the horizon.

Because iolite shows different colors depending on light direction, the Vikings rotated a thin iolite crystal to:

Identify the sun’s angle

Gem Clarity Scale

sushil agrawal Blog 0

GEM CLARITY SCALE

Gemstone clarity refers to the degree to which inclusions (tiny imperfections) are present in the gem. They can be minor inclusions or visible inclusions.

The occurrence, type, and acceptability of inclusions vary from one gemstone to the next. Emeralds, for example, tend to contain visible inclusions and are still more highly valued than most gems. Flawless diamonds, on the other hand, should have no inclusions at all.

However, unlike diamonds, there is no standard grading scale for colored gemstones. Generally, fewer noticeable inclusions or blemishes translate to higher prices. Still, there are some cases in which specific flaws actually increase the value of a stone (like in the case of emerald). Another example of this is the horsetail inclusion in green demantoid garnet.

Thus, the clarity of a colored gemstone must be measured against what is standard for that variety. Aquamarine, for instance, naturally tends to contain fewer inclusions than ruby.

Type 1 Gemstones

Type 1 gemstones include beryl gems, such as aquamarine, heliodor (golden beryl), and morganite; yellow and green chrysoberyl, pale-colored amethyst, citrine, smoky quartz, spodumene, tanzanite, diamond, and blue zircon. The gems in this category are usually found to be loupe clean (meaning they have no visible inclusions).

Type 2 Gemstones

Type 2 gemstones are generally found to be eye-clean rather than loupe-clean (meaning they have some inclusions, but these cannot be seen by the naked eye). Type 2 gemstones include amethyst, andalusite, alexandrite, garnet, and peridot.

Type 3 Gemstones

Type 3 gemstones include gem varieties such as green emerald, red beryl (bixbite), and varieties of tourmaline, particularly blue tourmaline (Paraiba tourmaline and Indicolite tourmaline), red (rubellite) tourmaline, pink, and bi-color tourmaline, and multi-color, or watermelon, tourmaline gems.

AAA Gemstone Clarity

“AAA” gem clarity grade is assigned to colored stones that are considered “near-perfect”. This means that, although these gemstones do show some variation in color, they are clean, well-cut, and polished. Despite not being loupe clean, AAA quality colored gemstones are the most sought-after precious stones for their perfect cut and vibrant color.

Colored Gemstones’ Clarity Grades

VVS	very, very small inclusions	VVS I: Minute inclusions, difficult to see under 10X magnification. Eye-clean. VVS II: Minor inclusions, somewhat easy to see with 10X loupe. Usually eye-clean. VVS III: Noticeable inclusions under 10X loupe. Usually eye-clean.
VSI	very small inclusions	VS I: Minor inclusions, somewhat easy to see with 10X loupe. Usually eye-clean. VS II: Noticeable inclusions under 10X magnification. May be eye visible. VS III: Obvious inclusions with 10X loupe. May be eye visible.
SI	small inclusions	SI1 I: Easily noticeable with 10X loupe. Slightly visible to the unaided eye. Usually low relief. SI1 II: Obvious inclusions, large or numerous under 10X magnification. Apparent to the unaided eye. SI1 III: Prominent inclusions to the unaided eye. SI2 I: Easily visible to the unaided eye. Usually low relief. SI2 II: Obvious inclusions, large or numerous under 10X magnification. Very apparent to the unaided eye. SI2 III: Very prominent to the unaided eye.

Uncover Gemstone Secrets

sushil agrawal Blog 0

Let’s dive into the world of fine quality iolite – one of the most elusive gemstones out there. High-grade iolite is indeed rare and highly sought after because of its distinctive features and striking appearance. If you want to delve deeper, explore detailed iolite gemstone information. In this piece, we’ll dig into what makes iolite so uncommon by looking at different sides of this fascinating stone. From its impressive colors to its eye-catching optical effects, we’re heading on a trip through the realm of iolite. Stick with us as we reveal what sets iolite apart as truly unique.

Key Takeaways:

Iolite is a rare gemstone
Iolite has a unique range of colors, from deep blue-violet to pale blue
Iolite exhibits pleochroism, resulting in mesmerizing optical effects
Iolite can be found in specific mining locations and is often compared to tanzanite and amethyst
The price and value of iolite can be influenced by several factors

The Stunning Colors of Iolite

One thing that makes iolite so intriguing is the variety of gorgeous colors it can show. Typically, you’ll see iolite in a rich blue-violet tone that’s similar to tanzanite or sapphire. But it also appears in softer blue shades that are light and vibrant.

These color differences in iolite come from elements like iron and magnesium, the way the crystals are oriented, and even the light around it. Plus, iolite is pleochroic, so it seems to shift colors depending on the viewing angle. This gives iolite a lively and ever-changing look that’s really captivating.

Captivating Pleochroic Properties of Iolite

Iolite isn’t just pretty; it also has impressive pleochroic traits that boost its appeal. Pleochroism means a gem can show various colors from different viewpoints.

When light hits an iolite crystal, it splits into two paths moving at different paces. This causes the stone to display varying colors based on the angle. For example, it might look deep blue-violet from one side and lighter blue from another.

What really stands out about iolite is its ability to show two colors simultaneously sometimes, called dichroism. Say, it could seem blue from one direction and yellowish-brown from another. These special visual effects make iolite a favorite for jewelry makers, particularly those wanting something with a surprise element.
