To commemorate the release of the book ``The Definitive Edition of Uncut Diamonds: How to Identify Quality and Determine Value'' written by Suwa Trading Chairman Kyoichi Suwa, we are selling a set of the first edition signed by Mr. Suwa and a diamond (hexagonal cut). I will do it.
When I interviewed him for KARATZ Gem Magazine for the release of his book, I was able to hear many interesting stories about uncut diamonds he has encountered over the past ten years, their charm, and anecdotes related to them. I did.

ピンセットだけちょっと残念

ルーペも使いやすいし、モスアゲートもルチルクォーツも可愛くていいんですけど、ピンセットだけ思ったより先っちょが硬くて、ルース掴んだ時に傷つけちゃいそうだったので、別サイトのラバーのピンセット買いました

宝石商の方も使っているペンライト

元々持っていたペンライトはカラーチェンジが弱いように感じて、こちらのペンライトを購入。やはりプロが使っているのは良いですね。一緒に届けていただいたフローライトのカラーチェンジもしっかり楽しめます!

絶対おすすめ!

インクルージョン編ということで、カラッツさんの本領発揮回かと思います。
特に袋から出して見るとよりリアルさを感じることができます。

ティンカーベルクォーツのカットの横の部分、サファイア、アクアマリンのインクルージョン…

実物で見る厚み感を感じ、これはもう一枚いる!と追加買いしました!

新品のよう

壊れてしまった指輪に、持ち主の息子は、ショックを受けていましたが、綺麗になおしていただいたので、とても喜んでいます。ありがとうございます。

綺麗に張り付いて、ルースを裏表で観察できるようになりました!カボション系だと大きくても張り付いてくれます。ちいさなおまけのサファイアたちもとてもかわいく、買ってよかったです!ルースが増えたらまた購入させていただきたいです。

折り紙で宝石を作れる夢の本です

難しいけどその分完成した時の達成感は高いです。
宝石ノートで初めて知ったブラッドショットアイオライトサンストーンに一目惚れして最近本物を買いました。推し石です。

素敵なセットでした

シールが気になっていたので購入しました。ラメが細かくて綺麗で角度を変えて眺めて楽しんでいます。ルーペも丁度欲しいと思っていたので良かったです。天然石の小瓶も可愛くて気に入っています。ありがとうございました。
