An Engagement Ring is a Token Lovingly Offered as a Proposal to Wed

It is a keepsake that signifies an unbreakable bond shared between two lovers. An engagement ring is the ultimate symbol of your love story. For these reasons, choosing the perfect engagement ring is a big decision! Here at The Sapphire Merchant, we make this process an extraordinary journey for you.

Where Do You Start When Conceptualising a Custom Engagement Ring?

Why not get out a pen and paper and start a brainstorming session? These things to think about will help you build the vision for your engagement ring.

Consider your significant other. The engagement ring is for them to wear and to enjoy for a lifetime to come. Designing a ring that best suits your partner's aesthetic should be considered. Some questions to ask yourself: Does my partner wear much jewellery? If they do, do they wear yellow gold or white gold (silver)? Do they wear simple designs? Or do they like jewellery that is a little more blingy? What is their favourite colour? Are they understated with their style, or are they a flamboyant fashionista? Keep the answers to these questions in mind when designing your custom engagement ring.

Consider Your Budget for Your Engagement Ring

Budget is one of the first factors to consider when choosing the right engagement ring. There are many traditions around engagements and weddings, and it was once said that the budget for an engagement ring should be the value of one month of your wage or salary earnings. This came about with a clever marketing campaign by De Beers (the largest diamond wholesaler in the world) after the great depression. Using the catchphrase 'diamonds are forever', De Beers added this guideline to their campaign, increasing diamond sales by 50%. In truth, your budget should be an amount you feel comfortable with. Consider that a custom engagement ring is a luxury item that weaves together precious coloured gemstones, diamonds and gold. You get what you pay for. It is an investment into your love story, a promise and a commitment. It is difficult to place a monetary value on an item that will be treated as priceless; however, think of it as the ultimate material token of your love for your significant other!

Our Top Engagement Ring Gemstone Picks:

Choosing the centre gem is the biggest decision when building your custom engagement ring. An engagement ring is generally built around this centre gemstone, which will likely inspire the entire ring.

Why Do Sapphires Make a Good Engagement Ring Gemstone?

Sapphires are the birthstone of September, and they symbolise commitment and faithfulness. Sapphires are by far the most popular engagement ring gemstone choice here in New Zealand and Australia and with good reason. Sapphires are durable! Just under a diamond on the hardness scale (9), they tolerate the wear and tear of everyday life and withstand the test of time! Sapphires come in over 1500 identified shades of colour, giving a vast range of choices regarding the look and personality of your engagement ring design. Given the broad range of carat sizes available and clarity gradings scaling from internally flawless to significantly included, sapphire options are accessible to everyone. There is a sapphire choice that will suit every aesthetic and be ideal for every engagement ring. 

Why Does Tourmaline Make a Good Engagement Ring Gemstone?

Tourmaline is the birthstone of October and symbolises serenity and wisdom. Tourmaline is an exceptional gemstone with vibrant colours, perfect cuts, and near-flawless clarity options. Tourmaline ranks lower on the hardness scale (7.5). The softer nature of this gem can be considered, with the design style and features of your tourmaline engagement ring tailored to offer it further protection and allow it to withstand the test of time. Tourmaline is renowned for its incredible pink, peach, and green shades, with more significant cuts and carat sizes generally better priced than comparable sapphires. When choosing a Tourmaline for an engagement ring, we advise that you select an internally flawless (IF) through to very slight inclusions (VS) clarity option. An inclusion-free, eye-clean stone will increase its durability. This rule doesn't extend to Paraiba Tourmaline, where significant inclusions are tolerated due to the extreme rarity of the gemstone. There is a perfect tourmaline choice that will suit every aesthetic and be ideal for every engagement ring.

Why Does Garnet Make a Good Engagement Ring Gemstone?

Garnet is an extraordinary gemstone! Garnet is the birthstone of January and signifies love and commitment. Demantoid, Rhodolite, Spessartite, and Tsavorite are the underdogs regarding engagement ring gemstone choices. We think Garnet is of a calibre of its own! There are multiple types of garnet, some extremely rare and only found in particular geographic locations. For this reason, it is sometimes opted for due to association with a person, a place, or a memory. Garnet has a high refractive index and an incredibly vibrant colour range, including greens, oranges and pinks. This means that a garnet sparkles with a brilliance that rivals a diamond. Using a garnet for an engagement ring takes you from the usual course of sapphires and diamonds and allows you to create something truly one-of-a-kind. There is a perfect garnet choice that will suit every aesthetic and be ideal for every engagement ring. 

The Hardness of the Gem Should Be Considered

When choosing an engagement ring, the hardness of the gem should be considered. We use the Mohs hardness scale to rank gems' durability and hardness. We advise that anything over a 7.00 on the Mohs hardness ranking is generally suitable for an engagement ring. However, given an engagement ring is worn day in and day out, the harder the gem the better. Here is a quick guide for the most popular gem choices for engagement rings based on hardness: Diamond ranks 10. Sapphire and Ruby rank 9. Spinel, Emerald, Aquamarine, Morganite, Rhodolite Garnet and Tsavorite Garnet rank 7.50. Tourmaline ranks 7. If you are opting for a gemstone lower on the hardness scale, we can create an engagement ring design that works to beautifully frame your gem and protect it so it withstands the test of time.

The Most Popular Gem Shape and Cut for an Engagement Ring

Considering the shape and cut of a gem is a great place to start when narrowing down the perfect gemstone for your engagement ring. For the person buying and designing, this is the perfect way to add your preference to the custom ring. Most gravitate toward a particular shape and usually favour one over the choices available. The most sought-after shapes/cuts for engagement rings are:

Cushion Shape

Emerald Shape

Heart Shape

Oval Shape

Pear Shape

Round Shape

Choosing a Gem Colour for My Engagement Ring

When choosing an engagement ring, colour adds visual interest and vibrance to your custom design. With the right colour choice, you can capture your partner's essence and personality. Consider what colours your significant other wears on a regular basis or if they have ever mentioned their favourite colours? Do they have a favourite flower? What catches their eye in nature? The answers to these questions may give you clues on a colour that will work well with skin tone and best suit their personality.

Symbolism of colour in coloured gemstones:

Green - new life, growth and ambition

Blue - fortune, intelligence and morality

Purple - inner peace and comfort

Red - passion, romance, power and sensuality

Orange - self-expression, brilliance and creativity

Pink - unconditional love and devotion

Peach - compassion, joy and tenderness

Yellow - happiness, energy and warmth

Choosing an Engagement Ring Style

Once you have chosen a centre gemstone for your engagement ring, the next task is to choose a setting that resonates with you. A little bit of your own research can go a long way. Use Pinterest or Instagram and search 'engagement ring'. Have a browse and see what engagement rings stand out to you. Narrow it down to the features. You may find several inspirational photos in which you can single out certain details. It is with these details we can create your own unique engagement.

Bring Your Engagement Ring Design to Life with CAD

The CAD (computer-aided design) process brings your engagement ring vision to fruition. This is where the magic happens! After gaining a clear understanding of your vision, our talented CAD designer goes to work creating a first draft CAD of your engagement ring. We present this to you, and from here, we can play around with all design aspects and make modifications as requested. We have no limit on how many modifications can be made. We work until your design is perfected. When you are completely in love with your engagement ring design, we then provide you with a final cost to have your heirloom engagement ring manufactured.
