Custom Jewellery & Engagement Rings

Specializing in Custom Jewelry Design for over 40 years, whatever your vision, Gemco Diamonds will work with you to design a ring that is uniquely you! Show us your favorite picture, sketch or idea and we will make it a reality!

The first step is to gather from your ideas (pictures, sketches etc of various rings etc). In order for us to have a clear idea of what style you are looking for, we will sit down with you and work with your ideas and have a CAD design made which will allow you to visualize how your ring would look from every angle. Based on your feedback, we’ll keep modifying your design until it is exactly what you are looking for.
Once the 3D version is ready, we use our 3D printers to create a wax version of the custom engagement ring.
Using the wax, we then create a mould into which the gold or platinum is poured, thus casting the engagement ring into life.
At this point the ring is passed on to our goldsmith and diamond setters who will hand finish your custom engagement ring.

Diamond Buying Guide

The Diamond Buying Guide

The 4C’s

Like a snowflake no two diamonds are exactly alike.

The 4Cs of Diamond Quality grading is the universal method for assessing the quality of any diamond, anywhere in the world.

The creation of the Diamond 4Cs meant two very important things: diamond quality could be communicated in a universal language, and diamond customers could now know exactly what they were about to purchase.

Colour

Although diamonds are essentially colourless, the term ‘colour’ refers white diamonds which are graded on a scale using the letters of the alphabet from D to Z.

The letters are based on the level of colour in the diamond, the rarest being in the ‘colourless’ D-F range. The closer along the scale you get towards Z, the more yellow is in the diamond.

With only the naked eye, it can be difficult to make out the difference between a diamond in the D-F colourless range and the G-J near colourless range, particularly after the diamond has been set within the ring.

Clarity

Clarity corresponds to the purity of a diamond. Most diamonds have tiny “birthmarks” known as inclusions. A diamond that has minimal inclusions and surface blemishes are rare and more valuable. This is because the smaller and fewer the inclusions, the more light can pass through the diamond, which contributes to its rare beauty.

Clarity Grading:

A gemologist classifies a diamond using a magnification level of 10 times the naked eye. Diamond clarity ratings are based on the type, position, size and number of inclusions in the diamond. Flawless and Internally Flawless diamonds are the most rare and therefore the most expensive with a clarity rating of FL or IF.

Carat

A diamond’s weight is measured in Carats and points. One carat equals one hundred points ( 0.01 carat = l point ). One carat is equal to 0.20 grams.

The higher the carat weight the more expensive the diamond. Half and full carat diamonds go up in price because of their demand. The Carat Weight of a diamond refers to the actual weight of the stone. So therefore, Carat also corresponds to the size of the diamond, as the larger the diamond is, the heavier it is.

The Cut

Diamonds are renowned for their ability to transmit light and sparkle so intensely. We often think of a diamond’s cut as shape (round, emerald, pear), but a diamond’s cut grade is really about how well a diamond’s facets interact with light.

Precise artistry and workmanship are required to fashion a stone so its proportions, symmetry, and polish deliver the magnificent return of light only possible in a diamond.
