Millesimal Fineness basically lists the percent of gold, while Karats lists how many parts of gold are contained in the piece. The remaining percent or parts that are not gold are alloys. The majority of gold sold on Jewellers Domain is 9k.


MEXICO:

The world’s biggest silver producing country is home to some of the finest silver reserves. Jewellers Domain is proud to offer designs direct from Mexico inspired by international trends, travel and a need for the unattainable.


STERLING SILVER:

An alloy of silver containing 92.5% silver and 7.5% of other metals, predominantly copper. Silver is a precious metal and much like gold is too fine to be utilized in its pure form. The sterling silver standard is 925 and for this reason all of Jewellers Domains silver designs are stamped 925.


RHODIUM AND RHODIUM PLATING

Rhodium is a precious metal and a member of the platinum family. Rhodium electroplating is used especially on jewelry to provide a surface that will resist scratches and tarnish, and give a white, reflective appearance. It is a rare, silvery-white, hard, corrosion-resistant and chemically inert transition metal. ... White gold is often plated with a thin rhodium layer to improve its appearance while sterling silver is often rhodium-plated for tarnish resistance. 


GOLD PLATING:

All gold plated Jewellers Domain jewellery has a base metal of solid sterling silver. Gold-plated jewellery is created using an electro-chemical process that places a layer of gold on top of the base metal. The thickness of the gold used throughout the collection is minimum 10k.


GOLD FILLED (GF).

This is similar to gold plate, but the gold is heat and pressure bonded to the base metal. It must have a minimum purity of 10K gold and the gold content must be at least 1/20th of the weight of the metal piece.


BASE METAL:

Base metal is a term used to indicate a metal that is not precious (such as silver or gold) Base metal generally refers to metals that oxidise and corrode easily. Examples are iron, copper, nickel, lead and zinc.


CRYSTAL:

Also known as ‘crystalline solid’ is a solid material whose constituent atoms, molecules or ions are arranged in an ordered manner extending in all three spatial dimensions. A crystal shares a visual and durable likeness to diamonds, yet is of a lower value.


CUBIC ZIRCONIA (CZ):

The cubic crystalline form of zirconium dioxide. The synthesized material is hard, optically flawless and usually colourless, but may be made in a variety of different colours. A cubic zirconia (CZ) also shares a visual and durable likeness to diamonds, yet of a lower cost.


HAEMATITE

Haematite is the mineral form of iron oxide. It can vary in colour from black to red but is most commonly seen as a steel grey colour.
