What Makes a Diamond Tennis Necklace Unique?
These unique necklaces have all the diamonds set in a long line. There will be no main centre stone or pendant.
They are typically round brilliants due to the shape fitting together well. Other shapes can also be used but need to be set accordingly.
The size of the stones will affect how the necklace looks. Smaller stones will give a more delicate look. Whereas larger stones will give a more obvious line. Diamonds will typically be a similar shade in order to give a balanced look.
The settings will also influence the look. Some will have very minimal metal showing. Others will have a more obvious setting.
Why Consider Lab-Grown Diamonds
Lab-grown diamonds have become an established choice for high quality jewellery. These diamonds can have the same qualities of natural diamonds but without being mined.
They are grown using technology. They will typically be grown using either Chemical Vapour Deposition or High Pressure High Temperature. They have the same chemical composition, crystal structure and optical properties as mined diamonds. They are different to other diamond alternatives such as moissanite and cubic zirconia.
The price tends to be cheaper than mined diamonds meaning you may want to consider a higher total carat weight or different design. However, just because they are cheaper doesn’t mean they will give you more value. You should still look at the quality of the diamonds, quality of craftsmanship and setting.
Retailers such as Novita Diamonds will give you the choice to purchase lab-grown diamond jewellery. This will help to see how the design and diamond specifications can affect the final piece.
How to Choose Quality Diamonds
When looking at man-made diamond tennis necklaces there are still the 4 Cs to look out for. However, the way you look at them will vary.
Cut & Colour
The cut of the diamonds will affect the way the light passes through and reflects back. If the lab diamonds are cut well they will give a nice sparkle. If they are not cut well they won’t look as lively.
The colour should also be the same as they are next to each other. If they are noticeably different it can ruin the uniform look.
Clarity & Carat Weight
The clarity will show you how many inclusions and blemishes there are. Due to the small sized stones it may not make much difference to have very high clarity grades.
The carat weight may also be something to note.
If the necklace is stated to be 6 carats this will typically be the total carat weight of all the lab diamonds. The individual stones will be much smaller.
Necklaces can look different even if they are the same total carat weight. If one has more diamonds but smaller ones it will look different.
Consider how many diamonds there are, the size of the individual diamonds and the length of the necklace.
Length & Settings
The length of the necklace will determine how it sits. The settings will also affect how flexible it is and how it will look.
Shorter necklaces will typically sit closer to the neck. Whereas longer necklaces will sit lower on the chest and may be easier to wear with variety of necklines.
Common lengths are:
14” – Usually a tight fit.
16” – Often around the base of the neck.
18” – Typically sits around/under the collarbone.
This can depend on the length of your neck and how it is constructed.
The settings will also need to be considered. Prong settings use small metal claws to hold the diamonds in place. This means more of the diamond is visible. Bezel settings will surround the lab diamonds with metal to give a clearer line.
Whatever design you go for the individual parts should move easily without twisting.
Metal Choice
The metal around the diamonds can affect how the whole piece looks.
White gold is often used as it has a pale colour to match the diamonds. Yellow gold will give a warmer look. Rose gold will give a slight pink tone.
Platinum is another option as it has a natural white colour and is good for high quality jewellery.
Depending on the metal you choose there may be different care requirements. White gold is often rhodium plated and may need re-plating. Platinum can also get a patina with regular wearing.
When comparing necklaces consider the purity of the metal, quality of settings and strength of the links.
The necklace should not only look nice but be constructed well for regular wearing.
Things to Consider When Buying Online
Images can only give you a general idea of what the necklace looks like. They won’t tell you how heavy it is, how it moves or how it is constructed.
Check the details carefully.
Make sure the total carat weight is listed, type of metal used, length of necklace, type of clasp and how high quality the diamonds are.
A secure clasp is especially important as there are diamonds throughout the whole necklace. Some will have a box clasp with extra safety catches to keep it secure.
Also check the images to see what it looks like from the back and individual settings.
If you are comparing different necklaces from Novita Diamonds it can be helpful to know the exact details of each piece. This will help you to see the differences between the necklaces.
Check the return policy, warranty and aftercare services. This is especially important for more expensive pieces.
How to Care for Man-Made Diamond Tennis Necklaces
Keeping your jewellery clean will help to keep it looking nice.
Oils from your skin, make-up and general grime can build up around the stones and settings. This can make the diamonds not look as sparkly even though they are not damaged.
You may want to clean them using a gentle cleaner. This can include mild soap, warm water and a soft brush. Make sure it is recommended by your jeweller.
Don’t tug or bend the individual links. Store them flat or in a suitable jewellery box. Don’t store with any jewellery that could scratch the metal.
It is also a good idea to have the settings and clasp checked regularly, especially if worn regularly.
If you purchase from Novita Diamonds or any jewellery retailers taking good care of your necklace will help to keep it looking nice.
