Topaz is often enhanced with treatment to produce the most desirable colors. The most popular color for topaz is blue, but in nature, blue topaz is usually pale blue rather than bright or deep blue. The brilliant blue shades of topaz are usually achieved by artificial means.
Deposits of topaz have been found in Brazil, Afghanistan, Australia, Myanmar (Burma), China, Germany, Japan, Madagascar, Mexico, Namibia, Nigeria, Pakistan, Russia, Zimbabwe, Sri Lanka, Ukraine and the USA. Natural light-blue topaz is found in Northern Ireland and the UK.
Topaz ranges from colorless (white) to yellow, orange, red-brown, light to dark-blue, pink to red, violet and light-green.

Peridot is not typically treated or enhanced in any way.
The ancient Romans called it 'evening emerald' since its color did not darken at night, but could still be appreciated by candlelight and the light of a campfire. It is a gem especially connected with ancient Egypt, and some historians believe that the famous emeralds of Cleopatra were actually peridot gems.
Natural citrine is actually quite rare and because it is more valuable than most other varieties of quartz, much of the citrine today is actually heat-treated to obtain its attractive golden color.
Citrine's color is thought to radiate positive energy. It is known as the 'success stone', since it is believed to promote prosperity and abundance, especially in situations involving business.
Although citrine deposits can be found all around the world, Brazil is the world's leading supplier. Other notable sources include Argentina, Bolivia, France, Madagascar, Myanmar (Burma), Namibia, Russia, Scotland, Spain, Uruguay and Zambia.
