The highest quality jade is in Burma Myanmar and one of the most important and economical green jade mines in northern Burma can be mentioned. The jade of this region is formed and metamorphosed due to the very high pressure of the Himalayan Mountains. Secondary deposits are also found among the layers of sedimentary rocks composed of conglomerate and sandstone in the riverbed. The size of the jadeite rubble here may be as large as sand or several tons of very large boulders. Despite the strict control of the Burmese government, most of these jade is still smuggled to and traded in Chiang Mai, China, or Thailand. Elsewhere in the world, we can mention the United States (California), Japan, Guatemala, and the CIS.
Geographically, much of the world's jade is found around the rim of the Pacific Ocean, where subduction transports large slabs of oceanic lithosphere beneath continents and volcanic island arcs. This accounts for much of the jade found in South America, Central America, the United States, Canada, eastern Asia, and New Zealand. Perhaps the most attractive and valuable jade found in the United States is from the area around Jeffrey City and Crooks Gap in Wyoming. There, nephrite jade is found by prospecting alluvial sediments, looking for jade in stream-rounded pebble- to boulder-size pieces.China, Russia, Guatemala and New Zealand have the richest quality reserves of quality nephrite.
Russia is home to significant jade deposits, particularly in the eastern part of the country. The Sayan Mountains, located in the Republic of Buryatia and the Irkutsk region, are known for producing nephrite jade.

Jade is a durable gemstone but can be damaged by harsh chemicals, prolonged water exposure, and rough surfaces. To maintain its quality, avoid using household cleaners and remove jade jewelry during activities that may cause damage. For cleaning, use a soft cloth or brush with warm water and mild soap. Store jade in a soft pouch to prevent scratches and avoid extreme temperatures to prevent cracks. Jade consists of nephrite and jadeite, with nephrite being less valuable due to its lower hardness. Professional cleaning is recommended for intricate pieces or significant dirt buildup.

The price of green jade varies significantly based on factors such as color, transparency, purity, weight, and extraction location. Prices can range from $1 to $1 million depending on these attributes. The most valuable jade is sourced from Myanmar, with annual trading occurring in major centers like Rangoon and Hong Kong. In these markets, jade is sold in various forms including carved jewelry and antiques. The quality of jade is crucial; uncut or unprocessed pieces pose risks as they may be misrepresented. For instance, Myanmar green jade can cost between $5 to $2,500 per gram, while Khorasani jade from Iran is priced below $1 per gram. Black jade generally has a lower price point than green jade, with values around $2-3 per gram. Antique jade pricing is complex and requires expert evaluation due to factors like age and historical significance. Raw jade stones are often sold by weight; in Iran, prices for raw jade can be under $50 per kilogram but vary widely based on quality.

Visual examination is the first step in jade stone detection, focusing on characteristics like color, transparency, and texture. Experts compare stones to known samples and assess their overall appearance. Density and hardness measurements help distinguish between jadeite and nephrite, with jadeite being harder. The classification system categorizes jade into types A (Imperial), B (treated), and C (low quality). Misidentification can occur as jade resembles emeralds but differs in color variety and market value. Jade"s historical classification evolved from a single mineral to two distinct types recognized by mineralogists. Advanced techniques such as refractive index measurement, spectroscopy, and X-ray diffraction are essential for accurate identification. These methods help detect synthetic or treated stones, while UV light can reveal fluorescence patterns unique to jadeite.
Expertise from gemologists is crucial for authenticating jade due to the high market value of genuine specimens. Understanding these detection methods is vital for buyers to avoid counterfeit stones. "

Jade quality is primarily determined by color, transparency, texture, and luster. Jadeite and nephrite exhibit a variety of colors, with vibrant hues being more desirable. Jadeite"s value increases with its transparency; high-quality jadeite is translucent, while nephrite is typically opaque. Jade is categorized into several grades: Category A represents high-quality jade with excellent color and transparency; Category B involves surface treatments that enhance appearance but compromise purity; Category C includes industrially dyed stones; Category B-C combines both methods; and Category D features a composite structure with plastic. Texture plays a crucial role in valuation, with smooth surfaces free from blemishes being preferred. Luster varies from matte to glassy, with bright reflections indicating higher quality. The craftsmanship involved in carving also significantly impacts jade"s value, as intricate designs and expert techniques enhance desirability.
