Synthetic Hydrothermal Quartz and Hydrothermal Quartz materials

HYDROTHERMAL QUARTZ - SYNTHETIC QUARTZ MATERIALS GEMSTONES

          Hydrothermal Quartz is grown in a hydrothermal process and moderate temperature but very high pressure. The process uses a thick pressure vessel able to with-stand the high pressure. Hydrothermal Quartz stones are also known as the Synthetic stones as it is the closest mankind has got to imitating the natural quartz. The hydrothermal quartz we supply here has the same chemical properties as the real amethyst.

Hydrothermal Quartz is a dense substance with the following properties:

SYNTHESIS:

Synthetic Quartz crystals are grown by hydrothermal method based on the temperature differences. In general, this process closely mimics how many crystals in nature originate from high temperature, high pressure water solutions. Hydrothermal method is also used in manufacturing high quality synthetic emeralds, rubies and sapphires. The ingredient materials are enclosed in a partially filled, sealed container of water solution called autoclave. 

Heated to high temperatures the feed materials are dissolved under high pressure and at point of cooling crystal growth is induced.

HISTORY:

The very first experimental studies on the synthesis of quartz were conducted with a mere purpose to determine the conditions of natural quartz formation. In 1845, C.E. Schafhautl first succeeded in crating a tiny quartz crystal. After that, small quartz crystals were created from silica dissolved in alkali water solutions at high temperatures and pressures.

The experiments were continued until two scientists, A.C.Walker and E.Buchler, arrived at the best combination of different conditions like temperature, pressure and other particulars to create synthetic quartz crystals. In their experiment, the crystals weighing 100-300 g were grown at a speed of 2.22 mm/day. Since then, the technology for creating synthetic quartz crystals has been developed to allow mass production.

COLORS AVAILABLE:

At present, we are offering a wide range of synthetic quartz varieties as, for instance, the following:
GREEN QUARTZ (PRASIOLITE) (SiO2 : Fe2+)

The colors and hues available: green, yellowish- or bluish-green. Some varieties correspond to green tourmaline color.
2;±crystal’s dimension (mm): 200x75x28
AMETHYST
Synthetic amethyst is the same violet to purple color as its natural counterpart. Few other synthetic gemstones so closely emulate their natural counterparts as synthetic amethyst does natural amethyst. The colors and hues available: purple, reddish- or bluish-purple. The crystals correspond to natural Ural amethyst color. The main physical characteristics of crystals are:

2;±crystal’s dimension (mm): 200x75x30
thickness of grown layer: 12-14 mm
AMETRINE
The colors and hues available: two-colored, with clear limits between citrine and amethyst zones. Some varieties correspond with Brazilian natural amethyst. 
dimension of citrine`s zone (mm): 28x30
width of amethyst grown layer: 8 - 10 mm;
CITRINE (SiO2 : Fe3+ Li+)
The colors and hues are: yellow, orange-yellow. Their color corresponds to the best hues of natural citrine. The characteristics of crystals are: 

2;±crystal’s dimension (mm): 200x75x30
Thickness grown layer: 12 - 15 mm;
BLUE QUARTZ (SiO2 : Co3+)
The colors and hues available: light blue, dark blue hue, medium light to moderately strong to strong saturation (ч 4-6/4-6). 

2;±crystal’s dimension (mm): 200x75x28
Thickness grown layer: 12 - 14 mm;
Synthetic quartz, especially its colored varieties, is still widely used as a gemstone and an ornamental stone. Apart from jewelry, the scope of application of optic and piezoelectric synthetic quartz crystals includes:

Computer hardware
Photo and telemetry
Digital photo and video cameras
Radio communications, telecommunications, and remote control
Automatic and control systems
Radar and radio navigation technology
Top quality substrates
Watches and clocks
