There are many factors that can affect the value of gold jewellery. Since gold is sold by weight, heavier pieces can be more costly than lighter ones. Designer jewellery also generally costs more, especially if it is a one-of-a-kind piece. Special finishes such as rhodium plating, matte or sandblasted, may also affect the cost of the piece.
Our prices do not include custom duties or other taxes which may be levied by your country. If required, these will have to be paid by yourself.
GC Manufacturing Jewellery uses industry standard alloys in all of our precious metals. 9K gold is 37.5% 14K gold is 58.5% gold and 18K gold is 75% gold. The composition of the remaining alloy varies, but yellow gold is most commonly blended with silver, copper, and zinc. Rose gold has a greater proportion of copper to give it a rosy hue. GC Manufacturing Jewellery's white gold is alloyed with palladium ONLY (along with fine silver) and plated with rhodium to brighten the white color. Platinum and palladium are both 95% pure and hypoallergenic. For both platinum and palladium, the 5% alloy is composed of other platinum group metals, ruthenium or iridium or a combination of the two, which varies from design to design.

It’s easy to get distracted by the beauty of a diamond before and after purchasing it. But, do bear in mind, if you’re planning on buying a diamond it is extremely important to make sure you receive a diamond certificate. Here’s a few reasons why it’s important to make sure you walk away with a credible diamond certificate after purchasing a diamond: A diamond certificate is a formal document that contains a detailed description of the specific diamond. The diamond dossier or diamond grading report contains verified information about the diamond’s unique characteristics; the cut, carat weight, colour and clarity with a few additional comments in regards to the diamond’s symmetry, polish and fluorescence. Having a diamond certificate is the best way to prove your unique gemstone’s identity.


The most recognizable and credible diamond grading laboratories in the world are the GIA (Gemological Institute of America) and EGL (European Gemological Laboratory). These grading laboratories are trusted by most well-known jewellers worldwide. Having a diamond certificate from the GIA or EGL, a buyer will be assured of the quality and value of the unique diamond. These diamond grading laboratories are fully independent, international organisations dedicated to upholding stringent diamond grading criteria to ensure diamonds are graded accurately and fairly according to world standards.

No, our rings are not hollow inside. Our products are solid and produced based on the metal properties selected by the customer.
Moissanite is a gemstone born from the stars. It was first discovered in 1893 by a French scientist named Henri Moissan, who later won the Nobel Prize in Chemistry. He discovered microscopic particles of the gem that would eventually bear his name in Arizona, in a crater created by a meteorite that fell to Earth. He initially thought that he had discovered diamonds, but later determined that the crystals were composed of silicon carbide. Natural moissanite is incredibly rare, so moissanite available today is laboratory-created. After many years of trial and error, the particles Moissan discovered were successfully synthesized to produce what is now one of the world’s most scintillating gemstones. READ MORE ABOUT MOISSANITE
Absolutely NOT! If you order your Diamond Ring with the central stone in moissanite, all the small stones in the Halo, Side Stone, Bridal Set, Three Stone or Vintage designs, will always be real diamonds. Wedding Rings for women and men are only available in with real diamonds.
While diamonds are graded on the 4 C’s scale (Cut, Clarity, Color, Carat), moissanites are graded solely on color. The cut and clarity is similar across different qualities of moissanites. At GC Manufacturing Jewellery, we offer Super Premium moissanites! Super Premium moissanites are IF / VVS Clarity, falling within the F-G range.
