OUR DIAMONDS

Natural mined diamonds free from all known treatments

Natural diamonds are those that are formed deep under the earth’s crust over millions of years, completely by nature without any human intervention. Both natural diamonds and synthetic diamonds can undergo a variety of artificial processes and treatments. Such processes are used to enhance certain quality characteristics making flaws appear more attractive and marketable, in particular their colour or clarity. Coating, irradiation, high temperature, high pressure, fracture filling and laser drilling are all examples of enhancement. These treatments alter a diamond from its natural state.

At Bartlett Master Jewellers we source diamonds that have been certified by independent and accredited diamond laboratories. This ensures you have a natural, untreated diamond that has been graded accurately.
