Beauty vs Practicality

SONY DSCOften in the world of engagement rings, jewellers constantly try to get a good balance between what looks good, and what will work well.  The US market tends to have their diamonds set very high as they want to show them off.  The NZ market prefers them a little lower as there is a perceived safety with this style.  The key here is that the ring should look well balanced with the diamonds.  A low set diamond, even though perceived as safer, can look a little flat and hides the beauty of the diamond.

Its definitely important to ensure the ring is practical to the lifestyle of your partner, but at the end of the day she wants her friends to say “Wow, what a beautiful looking ring”, and not “Wow, what a practical looking ring”.

At Global Diamonds, our jewellers work tirelessly to ensure every engagement ring is made and finished with amazing balance and proportions.

Our design team, led by Robyn, with many years of Jewellery design in Whangarei under her belt will be able to guide you in your decision.

Gemstones – Tanzanite

Here’s the first in a series of posts about some of the beautiful gemstones we have in store. Today’s featured gemstone is the Tanzanite.


The Tanzanite, found only in the Simanjiro district in Tanzania, was made famous by Tiffany & Co in the 1970s. Geologists believe that the chemical environment required to form the beautiful blue gem is so unique, chances of finding the same conditions elsewhere in the world are next to impossible. Experts estimate the probability of discovering another Tanzanite deposit is less than one in a million. The current source will run out within 10 years, after which time it will become unavailable as a new stone.
The natural colour of the Tanzanite is Blue, under artificial light it will have a slightly purple hue. Small stones are the most common size, a larger stone is rare.

We believe that Tanzanite would be a perfect investment stone, as the value will continue to increase. Perhaps the perfect gift for your children’s future financial security?

We would be happy to discuss any questions you may have either in store at 17 Rathbone Street, Whangarei, by emailing or by telephone on 0800 100 766

Treatments That Can Change Diamond Colours

8179-8181 copyWhen you purchase a white diamond ring, one of the factors that affects its value is its colour. The whiter the diamond, or the more colourless it is, the greater its value will be. The whitest diamonds allow a greater amount of light to pass through for a better sparkle and shine. These diamonds are rare, unlike diamonds with brownish or yellowish tones.


Fancy coloured diamonds are also extremely rare and expensive, but are not colourless. Instead, these diamonds are at the other end of the spectrum. Their value actually increases with their colour, which can range from bright yellow to blue to green.


The diamonds for your engagement rings are rated on an alphabetical scale, with D being the highest rating a white diamond can receive. The most expensive white diamonds are generally rated D, E, or F, while those with traces of brown or yellow in them are rated farther down the alphabetical scale, all the way to Z.


Because colourless diamonds are much more valuable, the jewellery industry has created a few methods for turning those lower scale diamonds into ones that are slightly more fancy. While some of these methods have been around for quite some time, others have only recently been developed.


Diamond Treatments


Colour Tricks and Coatings


Sometimes, the diamonds in your engagement rings may be covered with a coating that makes it difficult to see yellow traces in the diamond. This coating is applied with heat, but will eventually wear off over time.


Coloured dots of blue or purple ink can be painted onto diamonds to reduce the amount of yellow you are able to see. These dots are generally placed in areas that are obscured by the engagement ring setting, and are not permanent; they can generally be removed with cleaning solutions and water.


These diamond treatments are often not revealed to buyers before they make a purchase and are often used to deceive them.


Irradiation and High Heat


Sometimes jewellers turn ho-hum diamonds into fancy coloured diamonds through the use of irradiation, or exposing the diamond to radiation, and high heat. Most often, if the diamond isn’t exposed to high heat again during its life, the diamond will remain the fancy colour.


This trick generally isn’t used to deceive customers, but instead to allow those who can’t afford the price tag on fancy coloured engagement rings in NZ the opportunity to have a beautiful coloured diamond. However, those who purchase this kind of diamond need to understand that it is not a natural fancy coloured diamond and is not an investment.


High Pressure High Temperature (HPHT)


This controversial way of changing the colour of the diamonds in your engagement rings in NZ isn’t new, but the way the process is being used is. When this technique, which is similar to irradiation and high temperature treatments was first used to turn diamonds with yellow traces into fancy coloured ones, it is now capable of turning browning diamonds into colourless and expensive diamonds.


Steps are continually being taken to ensure that every buyer of engagement rings receives full disclosure about their diamonds and is not tricked into purchasing a diamond that has been artificially altered. The diamonds that are altered now must be laser inscribed with “irradiated” or “HPHT processed” or the name of a registered user in order to actually be graded.



While you may have thought a diamond was simply a diamond, when you purchase an engagement ring in NZ, you need to understand that some diamonds are altered to increase their value. Make sure you obtain full disclosure on your diamond ring so you can be sure you are buying the right one.

Precious Stones for Your Engagement Ring?

Using Precious Stones With Your Engagement Ring

There are four different precious stones available in the world. The first is the diamond, and it is the most popular option for diamond engagement rings. However, there are three others that can provide additional elegance and charm to your engagement setting. These precious stones are scarce, are hard and durable like diamonds, and have a rich colour your fiancée will love.

Why would you consider adding other precious stones to the same setting as your diamond? Let’s take a look at a few reasons this might be the right option for you.

  • Style – Precious gems like sapphires, rubies, and emeralds have just as much style as diamonds, and, just like Diamond rings, are available in a variety of colours. The deep, rich red of a ruby, the green of an emerald or the lovely blue of a sapphire can truly enhance your engagement ring. These precious stones are available in a wide range of beautiful cuts and can be set around your diamond.
  • Personality – Want to get a ring that matches the personality and unique sense of style of your partner? Precious stones can provide all the colour, style, and beauty your partner deserves and needs to match there personality.
  • Sentimental Value – Is Ruby the birthstone of the month the two of you first met? Maybe an Emerald reminds you of the green of there eyes. Maybe a Sapphire was there father’s birthstone and he is no longer with the family. You know they’d love for him to walk them down the aisle, but you are also aware that will never happen. A couple of carefully placed sapphires in the setting would show them that you truly take all there thoughts and emotions into consideration. Can you imagine there expression as you explain the meaning behind the precious stones?

The possibilities are truly only limited by your imagination when including precious stones in your engagement setting. While diamonds are the traditional choice for engagement rings, they don’t always have to be. Your ring can be as unique as your relationship.

The Only Proposal Guide You Will Ever Need to Read


For the most part, men understand how to propose to a woman. It’s a simple process. You purchase an engagement ring, find the perfect spot, and ask for her hand in marriage. Many women are looking to be surprised with so much more, though. While a proposal doesn’t necessarily need to be expensive or over-the-top, you should put your own unique spin on it. Keep in mind, “How did he ask you?” will be a question she’ll be answering for years.


How to Propose: The Essential Guide

Proposing to the woman of your dreams can play on your nerves; even if you’re confident she’ll say yes. Planning each step of the proposal is a fantastic way to shake off some of those nerves and prepare for one of the most memorable nights of your life. Here is an essential guide to help you pick out the perfect engagement ring and plan the perfect proposal.

  • Don’t Tell Your Friends- A proposal is almost always a surprise, so keep it that way. This will make it much less likely that someone will accidentally let your secret slip. You may want to discuss your intentions with her parents, but telling your friends can be a mistake.
  • Purchasing the Ring- Engagement rings come in various shapes and styles. Choose a diamond and setting that fits her style. If you need help, consult her mother or her best friend, as long as they are able to keep it a secret.
  • Hollywood It- Does she have a favourite movie? Many women are hopeless romantics and take cues from the movies they watch. If you can, find out what her favourite romantic movie is and take notes from it. This may sound like incredibly sappy advice, but take our word for it, she will be overjoyed.
  • Personalize It- Think about intimate secrets, jokes, or places you’ve shared together. Is there a particular park bench where you first met? Did you two use to play on a certain playground when you were children? Was your first date at the ice skating rink? Taking her back in time to the moment you first met can be an incredible place to propose.
  • Pay Attention to the Details- Once you decide how you are going to propose, make sure to pay attention to those little details that can take your proposal from ordinary to extraordinary. Recreate moments from your first date, first kiss, or even the first day you moved in together.
  • Capture It- Want to preserve the proposal for a lifetime? Make sure to record it. Have a friend, preferably someone she isn’t familiar with, record the event from a distance or set up a video recorder yourself.

With a little imagination and this helpful guide, you can select the perfect engagement ring, plan the perfect proposal, and confidently ask her to be yours forever.

How did you propose to the love of your life? We’d love to hear your story.

My Diamond Isn’t Flawless? A Practical Guide to Understanding Nature’s Creation

03 copyMost of us are aware of the fact that natural diamonds are formed deep within the Earth under intense pressure and heat. Well, with anything that is naturally made, there are also natural imperfections. For a diamond, they are like birthmarks and are completely expected. It’s true, your diamond isn’t flawless. To the naked eye it probably looks absolutely exquisite, but there are minor imperfections to be sure.

If you are just starting your search for the perfect engagement ring, here’s a quick guide to the flaws and imperfections you can expect. Some, such as cloudiness, you’ll want to avoid. This imperfection will affect the brilliance of the stone. On the other hand, a small carbon deposit, which looks like a fleck of pepper, can easily hide under a prong if it’s in the right place and not deter from the sparkle of your diamond at all.

Here’s Your Diamond Imperfection Guide

There are two major categories which diamond flaws fall under. External and internal. External flaws are generally removed in the polishing process. Internal flaws, also referred to as inclusions, are located within the stone itself and these are the imperfections you’ll be looking at when you are selecting your diamond engagement ring.

There are several different internal flaws to look for in a diamond. Keep in mind when looking for your perfect stone, the most important factors are brilliance (or the stones ability to reflect light), colour (you are usually looking for the absence of colour), and transparency (your ability to see through the stone without noticing cloudy areas or large deposits). This is all with the naked eye. With that in mind, here are the imperfections you can expect to find in diamonds:

  • Feathers – These tiny inclusions present in the interior of the stone resemble a feather in appearance.
  • Clouds  – are made up of a large number of microscopic crystals which will absorb light and take away from the brilliance of the diamond.
  • Carbon deposits –  tiny flecks within the diamond and can affect the grade if they are large and easily seen.
  • Pinpoints – are tiny flaws that can generally only be detected through a 10x jeweller’s loupe or microscope.
  • Included crystals – are the most common diamond inclusions and are formed when various types of crystals become trapped within the stone during the crystallization process. The effect they have on the grade the diamond is given depends on the clour as well as the size of the inclusion.
  • A knot – occurs during the polishing process when an inclusion becomes exposed. The knot will have a different appearance than the rest of the polished facets.

Should you be worried about flaws in your diamond? All Diamonds, under enough magnification, will have flaws. The only inclusions to be of concern are cracks which affect the integrity of your stone. Your jewellery professional will make you aware of this situation if it were to occur, but fine jewellery stores rarely include stones in their inventory which are severely included.

It is smart to educate yourself on the different flaws you may run into when comparing stones. This will keep you from being surprised. Since diamonds are created by nature, expect slight imperfections and be aware of which imperfections (cloudiness) will affect the way the stone appears so you can steer clear of those.
