Handcrafted jewellery Vs Ready-made jewellery?

Mass production is the producing of identical items in extremely large volume on a continuous basis. It is usually done on an assembly line by laborers who often use specialized machinery and have low skill levels.

When laborers produce jewellery on an assembly line, they aren’t putting the time or effort into making sure they are perfect and blemish free

ZCOVA take pride in the quality of our products. When a ZCOVA creates an item, you can be sure that time, talent, thought and energy go into its creation. Great effort has gone into each individual piece—making certain everyone is lovely and of the highest quality.

How about originality? When you buy mass produced, you get what everyone else has. Sometimes that’s fine, but one reason many people wear jewellery is to stand out. We want to wear jewellery that’s as unique and individual as we are. We want it to represent us as such. Your local chain department store may have some attractive jewellery, but it’s not really symbolic of who we are as individuals because everyone is wearing the same thing.

Moreover ZCOVA’s handcrafted jewellery cost is very competitive in comparison to mass produce pieces.

Diamond and Jewellery Information

What is fluorescence exactly?

Diamonds that are said to be fluorescent contain particles that emit a visible (usually blue) glow when exposed to UV lighting. In rare cases, high levels of fluorescence can make stone appear milky or hazy, although for the most part fluorescence does not generally impact beauty or sparkle and can even make some lower colours ( I,J,K,L etc) appears more colourless white.

Do all ZCOVA diamond products come with certification?

All our diamonds above 0.30 carats come with GIA Certification. Any diamonds below 0.30 carat has no certification. Our Sales Invoice serves as both the certification and warranty.

What precious metals do you use?

We offer the majority of our jewellery in 18k and 22k Gold (white, rose and yellow) and Platinum.Because of the density of platinum there are some more intricate pieces that cannot be produced in Platinum.

Why does my white gold jewellery turns yellow over time?

Your white gold ring is really yellow gold that is alloyed with nickel or palladium to “bleach” the gold to a white colour. Currently, the most common alloy of choice for the jewellery industry is nickel. Nickel is used as a whitener and the final polished white gold alloy remains slightly “gray-yellow” in appearance.

White gold is generally electroplated with bright rhodium to conceal the “gray-yellow” appearance. The result is bright and fabulous! Normally the yellow “tint” of the white gold would not be noticed if the rhodium layer has not worn off and the surface remains highly polished.

Most owners of white gold are somewhat surprised that their bright white gold now looks dull and yellow. As time progresses, exposure to chloride normally present in many household chemicals and skin perspiration will discolour the exposed white gold alloy to a darker gray-yellow colour.

What if I don't know my ring size?

With every purchase, we will provide you with a free ring sizer. The item will be couriered to you once payment has been made.

What if I order the wrong size?

Not to worry! Your first resize is always free of charge and you can come into our showroom to size finger correctly or alternatively, you can check at a local jeweler and then send the ring back to us. However, please take note that our resize allowance has a limitation of three sizes up or three sizes down. If the resize is out of the range, additional charges will be applied.

Can I add an engraving to my ring?

ZCOVA™ offers free engraving services (only once per purchase). All you have to do is include your personal message on the instruction card delivered together with the free ring sizer. A maximum of 10 character per ring

How can I get my ZCOVA™ piece polished and cleaned?

All of our products come with a complimentary 5-years polishing and cleaning service (claimable once every 6 months). However, we are unable to polish any jewellery with finishing such as satin or matte designs. Send us an email to request for polishing and cleaning services and drop by our office with your ring.

How quickly can you create and deliver a custom piece?

After we agree on a design, and make payment for the required deposit, most designs take a minimum of 15 to 20 working days for gold and a minimum for 5 weeks for platinum. A longer duration will be required depending on the complexity of design or festive seasons. Once you have approved the final design, we will inform your date of collection.
