Book "Gemstone Encyclopedia" (KARATZ, editor: Keiichiro Koyama)

KARATZ's first book, "Gemstone Encyclopedia," was released on July 20, 2023.
This book introduces over 300 types of gemstones with beautiful photographs, basic data, and their origins, as well as a gemstone purchasing diary and tips for photographing gemstones, making it a book that can be enjoyed by anyone, from beginners to gem enthusiasts.
It has received positive reviews from all quarters, and a sixth reprint will be scheduled for January 2025.

■Features of "Gemstone Encyclopedia"

Gemstones are mined all over the world and have fascinated people since ancient times.
We will be introducing over 300 types of stones, from famous stones that are widely known around the world, to gemstones that have appeared in manga and novels and attracted attention, to extremely rare stones that you don't usually hear about.
It also makes extensive use of images that KARATZ has accumulated over the years, so it's a feast for the eyes as well.

❖ Introduction to birthstones

The first part of the book introduces 29 Japanese birthstones along with their meanings, which were revised in December 2021.
Finally, there is a list page, which can be used as an opportunity to learn about the birthstones of family, friends, etc.

❖Gemstone encyclopedia page

The four great jewels of the world

The gemstone encyclopedia begins with an introduction to the well-known and four most precious stones in the world: diamonds, rubies, sapphires, and emeralds.
In addition to basic data and characteristics as a mineral, we explain it from various perspectives, such as characteristics by origin, where it is found, and world-famous gemstones.

Gemstones by Color

Other gemstones besides the four major gemstones are introduced by color. Each title page has been designed to display a list of representative gemstones of that color.

Even if the color family is the same, the atmosphere will be different depending on the colors mixed together. The image will also change depending on the transparency, cut, inclusions, etc.
I hope you can see the difference between the two pages side by side.

Gemstones that come in a variety of colors are introduced in the chapter on their most representative colors, and the color variations are made visible in the main photographs.

❖About unique jewels

Some gemstones incorporate other minerals during their formation, giving them their distinctive appearance, and some types change appearance depending on the light.
We introduce these unique gemstones divided into three categories based on their type.

The photos are large, so you can easily see the characteristics of each gemstone. This page is especially recommended for those who are new to gemstones and small children, and those who do not usually have much contact with gemstones.

❖Jewelry buying diary

KARATZ representative Koyama travels overseas several times a year to purchase gemstones in person.
Each country has different rules, which may affect the purchasing method, and each country has its own story. We will introduce the purchasing process in Sri Lanka and Thailand little by little.

❖Tips for photographing jewellery

Photographing jewelry is surprisingly difficult when you try it, and often the photos don't come out as they do when you see them. In this Q&A, the in-house photographer who photographs at KARATZ STORE will answer any concerns you may have about photographing jewelry. Be sure to check out the tips for taking great photos.

❖Handy size for easy portability

In addition to its handy size, it is printed on materials that take weight into consideration, making it so light that you won't even notice the 288 pages.
Its size makes it easy to carry around with minimal stress, so you can use it widely as something to read in your spare time or as a companion while shopping.

■ Thoughts on creating the "Gemstone Encyclopedia"

The Gemstone Encyclopedia is a book that can be enjoyed simply by looking at it, as it generously uses photos of beautiful gemstones that Caratz has taken over the years. Our staff, who are experts on the charm of gemstones, provide easy-to-understand explanations of basic data and characteristics of gemstones, along with photos of each gemstone, which they have lovingly taken. We hope that this book will help you discover the joy of living with the infinite charm of gemstones, and we hope that many people will pick it up and take a look.
