Figure Out Your Budget

First of all, before you do anything else, figure out what your budget is. You can buy a diamond engagement ring costing anywhere from a few hundred dollars to upwards of tens of thousands.


Decide on the Center Stone

A diamond is the traditional center stone for an engagement ring, but moissanites,sapphires, emeralds are popular choices too.


Choose the Setting Style

There are endless engagement ring settings to choose from, including solitaire settings, three-stone and multi-stone settings. Sometimes, the setting you choose will be influenced by your lifestyle.


Decide on the Metal

Choosing the metal to use for your engagement ring is largely a matter of personal preference. You might decide on white gold, rose or yellow gold to match your existing jewelry collection, or you could opt for platinum for a splash of extra style.


Design Your Own Engagement Ring

This isn’t compulsory, but it’s a tempting possibility. If you don’t fall in love with an engagement ring in our ready-to-wear collection, consider designing your own.

Prevent the need to clean by handling sparingly

Avoid touching your gemstones when handling your jewellery as oil from your skin can remain on the surface, dulling the sparkle of your diamond or Moissanite.


Avoid abrasive cleaners

Strong household chemicals, such as bleach or scouring powder, are likely to damage the setting around a precious stone. Do not use these chemicals or even toothpaste to clean the jewellery.


Use a soft touch when cleaning

A diamond can handle abrasive cleaning utensils such as a toothbrush or pad, but the setting that supports it cannot.
To keep your diamonds and Moissanite sparkling, use a reputable jewellery cleaner or a soft toothbrush and mild, soapy water to remove oils, lotions and dirt from your jewellery.


Store with care

Store your jewellery in separate compartments, as diamond can scratch another diamond or other gems in your collection. Use a soft-lined jewellery box, individual pouches, or wrap each piece in soft tissue paper to avoid scratches.


Professional cleaning is wise

Having a ring cleaned by a professional jeweler occasionally can serve two purposes. First, many jewelers use ultrasonic cleaners that are highly effective at removing accumulated grime and oils. Second, they will also inspect the setting afterward to ensure that mounts and their prongs are still strong and stable.

The Perfect Metal

Factors to Consider

First, if you have a color you are automatically attracted to, go with your gut! But if you can’t quite decide, there are a few factors to consider: luster, longevity, price, and weight. The metals are summarized below:

  • Platinum vs. White Gold

  • Luster, Longevity, and Color

  • What is the best for a metal allergy?

  • What are alloys and how are they used in gold?


If you're looking for the best, platinum is your metal. Denser than any other metal used in jewellery, platinum is also the most durable. The stronger the metal is, the more securely it will hold your diamonds as well. Because platinum is naturally pure white, it won't require any plating; its finish is already naturally stunning. It is also hypoallergenic, and the fact that it is tarnish resistant makes maintenance a breeze. Platinum is a rare precious metal – and that's reflected in its price.

Yellow Gold

In its 24k form, yellow gold is pure. 18k gold gets a quarter of its makeup for a combination of copper, silver, nickel, and zinc. The warmth of yellow gold against the white shine of a diamond makes it a classic pairing for engagement rings.
The percentage of yellow gold in jewellery varies and is referred to in karats, or K for short. Pure gold is referred to as 24K gold. Much of our jewellery collection is manufactured from 18K gold which is 75% gold and 25% metal alloys. 14K gold is made up of 58.3% gold and 41.7% other metals to give it extra strength.

White Gold

White gold is blended with copper, silver, nickel, and palladium, and has a white shine that contains more warmth than the silvery glint of platinum. Price-wise, it is more expensive than yellow gold but less than platinum. Most white gold engagement rings are actually plated (meaning coated) with rhodium to make them look more like platinum. This plating typically lasts about 4-6 months, at which point you'll notice the color start to change from pure white back to the natural yellowish-white color underneath. We don't recommend re-plating your engagement ring often; the process requires preparing the white gold first by buffing out all the scratches and polishing it to a high luster before applying the rhodium so it will adhere properly to the white gold. Every time the ring is buffed and polished, a thin top layer of metal is removed from the ring, weakening the prongs and beads that hold the diamonds. Re-plate too many times, and you'll have significantly weakened your ring.

Rose Gold

Rose gold is alloyed with copper and comes in shades ranging from a soft, blush pink to a reddish hue. Rose gold can be very complimentary against some skin tones but due to its copper content, it isn't recommended for people with sensitive skin or metal allergies.
