About coloured diamonds

Diamonds were first excavated in India approximately 3,000 years ago and
were originally appreciated for their ability to reflect and refract
light. Traders eventually brought these gemstones to other parts of the
world, but it wasn’t until the 1300s – when craftsmen learned how to
best cut diamonds – did their popularity and usage in jewelry and other
adornments take off. Almost immediately, diamonds became an obsession of
the rich and powerful.

From crown jewels to rumored pirate treasure, diamonds created fortunes,
fueled imaginations, forged alliances, and changed history. The wealthy
have long understood the value and power of diamonds (and coloured
diamonds in particular) and have likely benefited from the misnomer that
diamonds are for the elite only. We’re happy to work with clients of
different backgrounds to actualize their dreams by unveiling to them the
accessibility of the diamond market.

Today’s coloured diamond market is relatively niche, but is becoming
increasingly recognized for its investment and wealth potential. It’s
estimated that
coloured diamonds make up only one to two percent of the entire
natural diamond market
. Their rarity and beauty are big reasons why these gemstones command
higher prices and have long been sought after and collected by royals,
celebrities, and the wealthiest among us.

Timeless treasures

Not only are diamonds the hardest material found on earth, it’s
estimated that the coloured diamonds in circulation today were formed
between one and three billion years ago. There’s likely no other way you
could ever own something so near eternal.

With careful planning, know-how, and the help of trusted gemstone
dealers, everyday Canadians can also access this market and experience
the privilege of owning natural coloured diamonds – and even build
generational wealth through those acquisitions. Similar to bullion, a
coloured diamond is an asset that exists outside the stock and
financial market systems, and as such, can add diversity and hedging
within your portfolio or wealth plan.

Factors that influence the value of a coloured diamond

Each natural coloured diamond is one-of-a-kind, and its value is
determined on an individual basis. That said, there are several
factors that weigh into the price of a coloured diamond.

  • Colour rarity. Coloured diamonds are far
    rarer than white diamonds, and among coloured diamonds, certain
    colours are incredibly scarce. Red, purple, blue, pink, green,
    orange, and yellow diamonds are especially coveted because of their
  • Colour intensity. The hue, saturation,
    and tone all factor into the intensity of the diamond’s colour – and
    the more intense and visually striking a diamond is, the higher the
  • Carat (weight). The size of a diamond is
    gauged by weight, which is measured in carats. Larger diamonds are
    generally valued higher than smaller ones of comparative colour.
  • Cut. A well-cut diamond is one that is
    considered to have good symmetry and proportion, all of which show
    off its sparkle and brilliance. Preferences for different shapes
    (such as oval, round, square, pear, etc.) tend to be based on the
    buyer’s personal taste, especially if they intend to wear the
    diamond in a jewelry setting.
  • Clarity. Diamonds with few inclusions and
    blemishes, frequently referred to as “flawless”, will typically
    fetch a higher price.
  • Certification. The authenticity and
    characteristics of your diamond should be confirmed in writing by an
    expert – not just so you know what you’re getting, but so that an
    eventual sale of a diamond can be easier. Diamonds sold through
    Guildhall include certification recognized by the leading industry
    authority, the Gemological Institute of America (GIA).
  • Historical connections. Diamonds and
    jewelry that come with a story of their origin and ownership,
    especially those connected to historical importance, tend to
    captivate buyers.
  • Demand. The popularity and demand for
    certain coloured diamonds changes over time and can be influenced by
    a number of factors. For example, gemologists and dealers saw a
    notable uptick in demand for pink diamonds after Jennifer Lopez
    received one as an engagement ring.

Wealth you can wear: Loose diamonds vs. diamonds in a jewelry setting

Guildhall provides our clients with the opportunity to purchase cut
loose diamonds, diamonds already in jewelry settings, and jewelry
services where we can design bespoke pieces that incorporate your
loose diamonds. The decision to purchase or place a coloured diamond
in a jewelry setting is a personal one. Some factors worth considering

  • Beauty and fashion: The aesthetic
    attraction of diamonds is nearly universal. For decades, red carpets
    have featured stunning examples of beautifully crafted earrings,
    necklaces, rings, and bracelets featuring rare coloured diamonds.
    These brilliant pieces often draw just as much attention as the
    celebrity wearing them.
  • Luxury on display: Some clients love the
    extravagance and status that is symbolized by wearing ones’ diamonds
    in public or at a special event. It’s a privilege that few people
    get to experience, and a part of a client’s enjoyment of this unique
  • Added value: Skilled jewelers are able to
    elevate a diamond into a work of art thanks to the special details,
    additional gems, and precious metals used to create a piece of
    jewelry. Not only does this add interest, it can raise the total
    value of piece.
  • Sentimentality: Once placed in a jewelry
    setting, some of our clients consider the piece to be a family
    heirloom, which gives it an extra personal meaning.
  • Transparency: Some buyers prefer loose
    diamonds because you can get a complete 360-degree view of the
    diamond, and can confirm its characteristics and quality.
  • Taxation: Jewelry and loose diamonds are
    considered different kinds of assets, and, as such, have different
    tax implications related to their sale or gifting. For more
    information about this, we recommend speaking with an accountant.
  • Insurance needs: Because jewelry and
    loose diamonds are categorized differently in terms of asset type –
    and if a jewelry piece is sometimes worn in public – your insurance
    implications and coverage needs may be different. For more
    information about this, we recommend speaking with an insurance

Purchasing and Selling Section

Purchasing and selling coloured diamonds

Similar to bullion, coloured diamonds are the kind of purchase that’s best
capitalized with a long-term view. While prices are steadily rising, the
gains are most likely to be seen when one takes a patient approach.
Between taxes and broker commissions, it rarely makes financial sense to
“flip” a diamond purchase quickly. Undoubtedly, this is not how wealthy
diamond collectors made their fortunes.

The entrance into the coloured diamond market is typically higher than
most financial products, but with careful planning, our clients have been
able to access this exciting opportunity. Guildhall’s team can walk you
through each step of
finding and purchasing a coloured diamond that’s right for you.

We strongly advise anyone interested in buying or selling a coloured
diamond to go through expert channels, such as working with a diamond
dealer who has received training from the Gemological Institute of
America (GIA) and holds a membership in the Fancy Color Research
Foundation (FCRF), as this can greatly reduce the risk of fraud,
forgery, or unfair sales prices.

Once someone has made this thrilling investment, it’s common for clients
to want to hold onto their coloured diamond, as this one-of-a-kind
treasure gains both sentimental and financial value. In fact, many decide
they want to keep the coloured diamond in the family and arrange to
include it as part of their children’s or loved ones’ inheritance. In some
cases, a coloured diamond purchase lays the foundation for generational

However, should the need or opportunity to sell a coloured diamond arise –
sometimes to trade up to a larger coloured diamond purchase
– Guildhall’s team can be of service to broker that sale.

An investment that stands the test of time: Historical performance of
coloured diamonds

Since record-keeping began more than forty years ago, auction values have
rapidly increased alongside growing scarcity. Natural coloured diamonds
are a lasting global phenomenon with demonstrated market performance in a
changing world.

Diamonds are a long-term investment to be cherished and passed down
through generations. Guildhall recognizes the value – both financial and
sentimental – of your coloured diamonds, and we can advise on the best

independent appraisal for insurance purposes, which details fair market
replacement values should your diamond ever be stolen or lost.
