November birthstone

⌛Time it takes to read this article: < 1 minutesThe birthstones of November are topaz and citrine. Topaz is a common color with champagne color. Blue topaz also has natural color, but the distribution volume is negligible. Most of the blue topaz is treated to colored stones such as "Swiss blue" and "London blue" by gamma-ray irradiation and heat treatment. Natural stones also exist in citrine (yellow crystal), but there are also stones in which amethyst (purple crystal) is heat-treated and discolored yellow. The pendant in the photograph seems to be the treated stone.

October Birthstone and Halloween

⌛Time it takes to read this article: 2 minutesOctober's birthstones are opal and tourmaline. Among them, I especially like black opal and water opal. Also, when it comes to tourmalines, I like pink tourmaline and Paraiba tourmaline. Black opal and Paraiba tourmaline are high-quality gemstones, so it was difficult to collect them. Some of that collection is pasted below. 💎 Other jewelry is introduced on my jewelry collection website ⇒ Secret jewelry collection Actually, October 31st is my birthday.

September birthstone

⌛Time it takes to read this article: < 1 minutesSeptember's birthstone is sapphire. Sapphire belongs to the same ore called corundum that rubies do, and its composition consists of aluminum oxide (chemical formula: Al2O3). The most common color of sapphire is blue, but there are actually many other colors such as green, pink, orange, white, etc. Among them, I especially like sapphires with a cornflower blue (royal blue) color, which is considered the highest quality. In addition, from among the sapphires that I have collected, I have pasted the loose ones other than blue below. Among these, natural Padparadscha sapphires produced in Sri Lanka are the rarest. Pink sapphires are beautiful and cute, but when they turn red, they are called rubies rather than sapphires. (^_^;)

Birthstone in May

⌛Time it takes to read this article: 2 minutesEmerald – Ring (emeald + melee diamonds) & Pendant made in Cambodia (synthesis stone) 5月の誕生石は、翡翠とエメラルドです。 💎 グリーンは、癒やしのカラーとされていて、見ていると確かに気持ちが癒やされますね。 実のところ、エメラルドは私の大好きな宝石の一つであり、私の「秘密のジュエリーコレクション」のサイトの中でも案外多く集めています。 エメラルドの和名は、緑柱石と呼ばれています。鉱物名はベリルで、主成分は、ベリリュウム(元素記号:Be)です。その結晶が六角柱の形状をしているのが特徴的な宝石です。 エメラルドのモース硬度は、7.5と比較的硬いのですが、割れやすいという弱点があるため、ルースにする時は、なるべく割れにくいようなカット(エメラルドカット等)に加工されます。 他のグリーン系の石としては、翡翠、アマゾナイト、デマトイド・ガーネット、クロムダイオプサイト、グリーントルマリン、ツァボライト、グリーン・アゲート等、他にも綺麗な石が沢山あります。 その中でも、特にロシア産のデマントイド・ガーネットが一番稀少かと思います。 エメラルドの主な産地は、コロンビア(ムゾー鉱山など)やブラジルです。翡翠の産地は、ミャンマーや中国ですが、日本の新潟県糸魚川でも採れるそうです。 以下は、エメラルドと翡翠のギャラリーです。 Emerald – Loose stones Emerald – Loose stones (close-up) Emerald – Synthesis crystal stone & Natural Gemstone Emerald – Synthesis crystal stone & Natural Gemstone (close-up) Jade – Ring & Loose stones Jade – Gemstone Jade – Mouse pad 💎 その他の宝石を見るにはこちらをクリックして下さい ⇒ 秘密のジュエリーコレクション
