ご覧いただきありがとうございます。

本品は《天然ベリル(エメラルド)原石 35.800ct》です。

単なる大粒原石ではなく、結晶成長史をそのまま内部に保存した
「研究標本として価値の高い個体」です。

宝飾用の評価軸ではなく、
結晶学・鉱物学の視点から唯一性を重視される方に向けた出品となります。


■ 結晶学的特徴①:中心部の白濁 ― 再結晶(リヒーリング)の明瞭な痕跡
中心部には白濁した再結晶領域が確認できます。
これは結晶成長の過程で、

・温度・圧力の急変  
・流体組成の変化  
・成長の停止 → 再成長  

といった環境変動が起きた際に生じる、天然エメラルド特有の成長履歴です。
ここまで明瞭に観察できる個体は多くなく、
結晶内部の“時間の層”を読み取れる標本として価値があります。


■ 結晶学的特徴②:側面からの新結晶 ― 成長方向の変化を示すエピタキシャル成長
横方向に伸びる結晶は、割れや欠損ではなく、
後期成長によって付加された新しい結晶(エピタキシャル成長)です。

・主結晶と角度の異なる結晶面  
・溶着するように連続した境界  
・成長時期の違いによる微妙な色調差  

これらは、母岩から供給される流体の方向が変化した証拠です。
エメラルド原石で成長方向の変化が視覚的に分かる個体は非常に希少です。


■ 結晶学的特徴③:大型原石としては異例の透明度
エメラルドはインクルージョンが多い鉱物ですが、
本品は35.800ctというサイズにもかかわらず透明度が高い点が特徴です。

これは長期間安定した“静穏期”が存在した証拠であり、
結晶学的にも重要な情報を含んでいます。

(透明材の含浸処理は行われていると思われます。
 そのため宝石ルースとしての位置づけとなります。)


■ この石の位置づけ
本品は、

・再結晶痕(リヒーリング)が明瞭  
・側面の新結晶が観察できる  
・成長方向の変化が視覚的に分かる  
・大型で透明度が高い  
・結晶成長史を一つの個体で追える  

という点から、
「結晶成長の記録をそのまま封じ込めた標本」として価値の高い個体です。

宝飾用の評価軸では測れない、
鉱物標本としての唯一性・研究価値を重視される方におすすめいたします。
