Trapezoid Diamond Engagement Rings

Lars — Thu, 15 Dec 2011 02:11:00 +1100

A trapezoid diamond has four sides and is similar to a triangle with one point missing. Trapezoids are available in both brilliant and step cuts; each giving a unique look so it is recommended to view both options during your diamond appointment.

Trapezoids are most often used to frame a centre diamond on the left and right sides, creating an angular three stone effect. It works best when the centre stone is of emerald, princess or asscher shape as each of these has flat sides for the trapezoids to sit against.

In terms of proportion, the trapezoids should be smaller than the centre diamond, even if just slightly.

Trapezoids are becoming an increasingly popular option in diamond engagement rings, and offer a great alternative to baguette and trillion cuts, which are often used for the same purpose.

For those wanting diamonds to frame their oval or cushion cut centre diamond, crescent trapezoids are the answer.

The longest edge of a crescent trapezoid is curved inwards, which allows the stone to sit comfortably against rounded diamonds.

GIA Certified Diamonds

Lars — Thu, 15 Dec 2011 02:00:00 +1100

The GIA (Gemological Institute of America) was established in 1931 and is the world’s foremost authority on diamonds, coloured gemstones, and pearls.

GIA’s certifications are therefore highly trusted within the jewellery industry and purchasing a GIA certified diamond ensures a safe purchase.

“GIA exists to protect all purchasers of gemstones, by providing the education, laboratory services, research, and instruments needed to accurately and objectively determine gemstone quality.”

The term ‘The 4 C’s’ was created by the GIA, as well as the D-Z colour scale and Flawless to I3 clarity scale.

Larsen Jewellery specialises in custom made diamond rings, as well as the sale of loose diamonds and coloured gemstones certified by the GIA.

To view a range of GIA certified loose diamonds, as well as their certificates, please contact Larsen Jewellery in Sydney 02 9223 2006 or Melbourne 03 9662 3005.

Diamond Prices

Lars — Thu, 06 Oct 2011 03:29:00 +1100

Asking the price of a diamond is akin to asking the price of a car, it depends on many factors.

The price of a diamond is largely determined by the carat size, colour, clarity and cut of the individual stone and whether or not it has been certified. There are also certain stones that are significantly more expensive than others due to their rarity, such as pink and blue diamonds.
Every individual diamond is unique and will be priced accordingly, based on its overall quality, grading and characteristics.

A recommended way to receive more information on pricing is to contact a reputable Jeweller that specialises in the sale of loose diamonds.

Once you have viewed a selection of diamonds, you will find some elements to be more important to you than others. For example, you may prefer to have a larger diamond and step down one grade in colour, whereas others may prefer a smaller stone of higher colour grade.

It is also recommended that you choose the diamond, within your price range that catches your eye the most during a viewing. When comparing a $1,500 diamond with a $10,000 diamond, you may well find that you prefer the overall look of less-expensive stone. In other words, sometimes it’s best to choose your stone visually than to worry about what its particular specifications are.

Another strong influence on diamond pricing is the cut grade. The cut grade represents how well the stone has been cut to reflect light and create sparkle, which is the most important contributing factor of them all. Even the highest grade of diamond will look dull if cut poorly. The highest cut grade is ‘Excellent’.

Larsen Jewellery’s talented team of diamond experts can assist you in making an educated decision when purchasing a diamond. Upon a no-obligation appointment they will show you a selection of loose diamonds to choose from, all within your price range and at competitive workshop prices.

Black Diamonds

Lars — Thu, 08 Sep 2011 03:42:00 +1100

Larsen Jewellery specialises in custom made fine diamond jewellery. We can create your dream piece of jewellery to the highest standard of workmanship, involving you in the entire process.

Whether you’re after loose diamonds, an engagement ring, wedding rings or a gift for someone special, our team of expert Jewellers can happily assist you.

Diamonds come in a dazzling array of shades, from classic whites to rare pinks and yellows. The beauty of black diamonds, however, is somewhat underestimated by buyers and many people are still unaware of their existence.

More recently, celebrities such as Carmen Electra, Lauren Conrad and Sara Thompson – fiancé of Australian swimmer Geoff Huegill, are placing black diamonds into the spotlight by using these precious black gemstones in their engagement and dress rings. This in turn has sparked a new trend which is making black diamonds, also known as ‘Carbonado’, the latest and most coveted gemstone of choice.

Black diamonds are slightly more porous than white diamonds, although they are very strong and are therefore a great choice for engagement and wedding rings. They are made of the same crystalline structure as white diamonds, with the difference being its inclusions of Carbon Graphite, Magnetite and Hematite; creating a dramatic change of colour in the stone. Shades range from a dense black, to weaker charcoal-black hues.

Being opaque in clarity, they absorb light rather than reflect it, meaning they don’t sparkle in the same way other diamonds do. Regardless of this, they are mysteriously elegant and have a certain intrigue that no other gemstone can replicate.

They are also very budget-friendly, costing significantly less than white diamonds.

Pear Cut Diamond Ring

Lars — Tue, 09 Aug 2011 04:15:00 +1100

The Pear cut diamond, also known as the tear-drop cut was created using the best elements of both the Marquise and Oval shaped diamond cuts.

The Pear cut diamond ring is not as common as a Round or Princess cut diamond ring and is therefore a perfect option for those wanting something unique and different.

The team of expert Jewellers at Larsen Jewellery in Sydney and Melbourne can show you a selection of beautiful Pear cut diamonds to choose from, which you can then have set into your personally customised ring design.

It’s important to select Pear shaped diamonds based on the highest cut and symmetry grades to ensure the stone is as symmetrical as possible and demonstrates fire or ‘sparkle’. Lower cut grades tend to show darkness in the centre of the stone which will in turn negatively affect even the most brilliant diamonds of the highest colour and clarity.

Another element to consider when choosing a Pear cut diamond is the width to length ratio. There is no ‘correct’ ratio but rather it is a matter of personal taste. The longer, narrower cuts can look fantastic in earrings and pendants; whereas the shorter and wider cuts are a wonderful choice for a Pear cut diamond ring or engagement ring.

Conflict Diamonds

Lars — Tue, 07 Jun 2011 05:51:00 +1100

Conflict diamonds (also known as ‘blood diamonds’), are diamonds that are mined and traded through violent and illegal means. These diamonds are then sold to fund civil war and terrorism. The conflict diamond trade is a multi-billion dollar industry and millions of lives have been lost as a result.

This illegal trade has fuelled brutality and war in places such as Sierra Leone, Angola and the Democratic Republic of Congo (DRC); where rebels and warmongers controlled civilians and breached human rights using weapons which were funded by the sale of conflict diamonds.

In 2003, the United Nations established an initiative to prevent diamond sales from funding violence. The Kimberley Process Certification Scheme (KPCS) imposes requirements on participants to certify that shipments of rough diamonds are conflict-free. The purpose of the scheme is to prevent conflict diamonds from entering the market and being sold, which would in turn evaporate criminal funding. This initiative also protects individuals from unknowingly purchasing conflict diamonds.

Today, conflict diamonds are estimated to account for less than 1% of world diamond production.

Larsen Jewellery does not sell or deal with any suppliers who are, or may be, involved with conflict diamonds. Larsen Jewellery is also a proud member of the Jewellers Association of Australia and the Goldsmiths Guild of Australia.

The Taylor-Burton Diamond

Lars — Mon, 13 Dec 2010 00:59:00 +1100

One of the most famous ‘modern’ cuts must be the Taylor-Burton diamond, a 69.42 carat, D-Colour, Flawless, Pear Shape Brilliant Cut, which created a sensation when it was purchased in 1969 for Elizabeth Taylor by her husband, the Late Richard Burton.

The diamond was cut from a 240.80 carat rough diamond found in the famous Premier Mine in 1966. It was cut by renowned New York diamantaire, Harry Winston, who commented at the time that he doubted if there had been more than six diamonds in the world of the same quality. The rough diamond yielded two perfect stones of which the Taylor-Burton was the largest.

The diamond was first purchased, in 1967, by a Mrs. Harriet Annenberg-Ames, the sister of Walter Annenberg, the US Ambassador to London during the Richard Nixon administration.

Two years later, on October 23rd 1969, the diamond was offered for sale at a landmark auction, in New York, which gave the successful bidder the right to ‘name’ the diamond. The auction attracted many interested buyers including Richard Burton, Harry Winston and Robert Kenmore the owner of Cartier Inc. In the record-breaking auction, Kenmore emerged the winner with a bid of US$1,050,000 and immediately named the Diamond ‘The Cartier’.

Still determined to obtain the diamond, Richard Burton contacted Cartier the following day and successfully negotiated the purchase of the diamond for an undisclosed price. As part of the deal Richard Burton agreed to allow Cartier to display the renamed ‘Taylor-Burton’ diamond for a limited period at their New York showroom.

Elizabeth Taylor wore the diamond for the first time on October 12th 1969, when she attended Princess Grace’s 40th Birthday in Monaco. Nine years later, in 1978, following her divorce from Richard Burton, Miss Taylor announced that she was putting the diamond up for sale and that the proceeds would be used to fund the building of a hospital in Botswana. The diamond was bought, for a reported US$5,000,000 by New York jeweller Henry Lambert. It has since been purchased by the famous jeweller and collector Robert Mouawad.

Brilliant Cut Diamond Shape & Style

Lars — Mon, 06 Dec 2010 03:10:00 +1100

The modern round Brilliant Cut diamond has 57 facets, or 58 facets with an open cutlet, arranged in the classic, 8-fold brilliant style.

The upper part of the diamond is called the CROWN and has 33 facets, including the table. The lower part is called the PAVILION and has 24 facets, or 25 facets with an open cutlet.

The TABLE is the uppermost and largest of the crown facets and acts as the principal window for light entering and reflecting back from a diamond. Virtually all of the light returned through the table is made up of white light or brilliance.

The BEZEL is the sloping part of the crown, between the table and the girdle. It comprises 8 main crown or bezel facets, 8 star facets and 16 upper girdle facets. These facets work together to both reflect and refract light, returning a combination of brilliance and fire.

The GIRDLE is the narrow section, between the crown and pavilion, the outline of which describes the ‘face-up’ shape of the diamond and acts as the setting edge. The girdle may either be frosted (bruted), polished smooth or polished with facets.

The PAVILION comprises 8 main pavilion facets and 16 lower girdle facets, all of which are designed to act as internal mirrors to reflect light entering through the crown facets and return it back through the crown.

The CULET is the lowest point at the base of the pavilion. Often a small facet is added here in order to prevent damage. In this case the term ‘open culet’ is used. When there is no facet, the terms ‘closed culet’, ‘pointed culet’ or simply ‘none’ are used.
