Purpose of the development: THERMORADIATIVE technology upgrading jewelry minerals (TYuM) is a set of operations irradiation jewelry minerals ionizing radiation (gamma rays, fast electrons, X-rays) at certain temperatures or with subsequent heat treatment, which lead to sustainable change in the color of the mineral, increases its use value as a material for jewelry.

Advantages over analogues: For example, diamond is a natural emerald green color (very rare) costs approximately $ 6,000 per carat. Brilliant brown tint (the cheapest) - an average of $ 600 per carat. Special radiation-thermal processing of brown diamonds allows you to change the color of the emerald green. By varying the conditions of irradiation fails to ensure that the stone has acquired green, blue, gold, canary (yellow) and brandy (champagne) color. Under certain combinations of impurities (which depends on the diamond deposits) can be pink and purple tones. Similar effects are achieved TYuM on minerals such as amethyst, beryl, corundum, topaz, tourmaline, sapphire, citrine, and others. And the effects are realized further discoloration, hiding and revealing irregularities in color, internal defects, etc.

The development stage readiness: Ready for application

Technical and economic effect: Natural stone (class) - the price of pale colors - bright colors price - possible colors thermoradiation after treatment: Emerald (1) - $ 500 / carat - $ 5000 / ct - blue-green; Topaz (2) - 1-2 $ / carat - 11 $ / ct - blue, orange; Aquamarine (2) - $ 1.5-5 / ct - $ 20-70 / carat - Blue-Green; Tourmaline (2) - 1-5 $ / carat - 70-100 $ / carat - green, pink; Citrine (4) - 1-2 $ / carat - 12 $ / carat - yellow, green; quartz (4) - 1-2 $ / carat - $ 12-70 / carat - pink, purple.

Description of the development:
()
TYuM based on the ability of ionizing radiation influence the thermally stimulated processes of change in the phase state of the impurities that determine a set of color centers of the mineral; create defects in the bulk crystal structure, are new color centers.
