Цвет искусственного алмаза зависит от химических добавок и облучения

Quick Look

  • Цвет лабораторных алмазов определяется добавлением химических элементов и облучением: азот дает желтый, бор — голубой и синий, розовые и зеленые получают после синтеза через облучение.
  • Российская компания New Diamond Technology вырастила желтый кристалл весом 129 карат за 400 часов в 2020 году.
  • К середине 2024 года самый крупный ограненный лабораторный бриллиант весил 75 карат, а его заготовка в 190 карат росла около девяти месяцев.

Цвет искусственного алмаза определяется добавлением различных химических элементов и облучением.

Желтый кристалл на 129 карат был выращен за 400 часов российской New Diamond Technology в 2020 году.

Самый крупный ограненный лабораторный бриллиант на середину 2024 года весит 75 карат, его заготовка в 190 карат росла около девяти месяцев.

МОСКВА, 1 окт - РИА Новости. Цвет искусственного алмаза определяется добавлением различных химических элементов, а также путем облучения, в частности, голубой оттенок получается с помощью бора, рассказал РИА Новости эксперт НТИ по новым материалам и технологиям Евгений Вишневский.

"Палитру лабораторного алмаза задает то, что попало в камеру вместе с углеродом. Азот дает желтый, бор - голубой и синий. Рост без добавок чаще уводит камень в коричневый и серый, а бесцветный остается самой трудной задачей и требует самого долгого цикла. Розовые и зеленые получают уже после синтеза, облучением", - сказал он.

Говоря про создание формы камней, Вишневский привел в пример желтый кристалл на 129 карат, который был выращен за 400 часов российской New Diamond Technology в 2020 году. Самый крупный ограненный лабораторный бриллиант на середину 2024 года весит 75 карат, его заготовка в 190 карат росла около девяти месяцев. Самый тяжелый лабораторный кристалл в мировых реестрах - это 150 карат.
