With so many colours and possibilities to choose from, selecting the perfect gemstone might seem like a daunting task. This guide will walk you through the key characteristics of gemstones to look out for to decide on one that complements your style.
Key Takeaways
- Start by getting familiar with gemstone basics, including the different types, their properties, and what makes them unique.
- Pay close attention to the quality of gemstones by understanding the 4 C’s (colour, clarity, cut, and carat weight), which are crucial in determining a gemstone's value and beauty.
- Consider the different types of gemstone jewellery available and think about what matches your personal style and needs. Whether it's a ring, necklace or bracelet, the right piece can add a meaningful touch to your collection.
- Finding the right gemstone for you involves more than just aesthetics. Its hardness or durability also determines how suitable each gemstone is for your lifestyle.
Understanding Gemstone Basics
When selecting a gemstone, it's crucial to understand the characteristics that define its quality and value. These include the 4 C’s of colour, cut, clarity and carat weight as well as hardness.
Colour
Color is one of the most significant factors in gemstone selection. It is evaluated based on three main components: hue, saturation, and tone.
- Hue refers to the gemstone's basic colour, such as blue, red, or green.
- Saturation measures the intensity or purity of the colour. High saturation means a vivid, rich colour, while low saturation results in a more muted hue.
- Tone indicates the lightness or darkness of the colour, ranging from very light to very dark.
The ideal combination of hue, saturation, and tone varies depending on the type of gemstone. For example, the best sapphires have a deep, vivid blue colour, while top-quality emeralds exhibit a rich, vibrant green.
Clarity & Inclusions
Clarity refers to the presence of internal or external flaws, known as inclusions and blemishes, respectively. When evaluating clarity, consider the size, number, location, and visibility of inclusions or blemishes. Gemstones are graded on a clarity scale, where higher grades indicate higher value with fewer and less visible inclusions.
However, some inclusions can be characteristic of certain gemstones such as emeralds, which often contain inclusions known as jardin that are accepted as part of their natural charm.
Cut
A gemstone's cut directly influences its brilliance and how well it showcases colour depth. A well-executed cut is symmetrical, well-polished and reflects light evenly across the stone’s surface. In comparison, poorly cut gemstones may appear dull.
Different cuts can dramatically change the overall look and feel of a gemstone. A sapphire displays more depth of colour in an oval cut than in a princess cut, while an emerald showcases more of its lush green colour and superior clarity with a step cut. When choosing your gemstone, consider how the cut affects the gemstone and what your preferences are.
Carat Weight
Carat weight measures the perceived value and rarity of a gemstone. Larger stones are rarer, especially when they maintain high colour quality and clarity, making them more expensive.
Take into account that two gemstones of the same carat weight can appear different in size due to their respective densities and cuts.
Hardness
All gemstones are ranked on Mohs scale, which measures hardness and resistance to scratching. Diamond is the hardest, registering at 10 or the highest level of hardness. Other popular precious stones such as sapphire or ruby are graded at 9, slightly less hard but still extremely durable.
Selecting Quality Gemstones
Grading
Unlike diamonds, which follow a standardized grading system, gemstones lack a universal scale. This can make comparison and evaluation challenging for buyers. The ‘A’ grading system is one informal method used by some retailers, ranging from A (lower quality) to AAAA or even AAAAA (highest quality), though this method varies across retailers. The Gemological Institute of America (GIA) offers a clarity-based grading specifically for coloured stones, though it is less about ranking and more about describing the gem's appearance.
Assessing Durability
Durability is crucial when selecting a gemstone, especially if it will be worn daily. Hardness and toughness are key factors; hardness determines how well a gem resists scratches, while toughness refers to its ability to withstand breaking or chipping. For example, diamonds, sapphires, and rubies are suitable for everyday wear due to their high hardness levels. On the other hand, opals and pearls are more delicate, making them better suited for occasional use. The intended use should guide your choice; precious gemstones like diamonds are perfect for engagement rings that endure constant wear, whereas softer, beautiful gemstones might be reserved for pendants or earrings.
Certification
Certification from a reputable gemological laboratory such as the GIA provides assurance of a gemstone's quality and authenticity. Certificates typically include detailed information about the gemstone's characteristics, including its 4 Cs, any treatments or enhancements, and its origin.
Choosing the Right Gemstone
Precious & Semi-Precious
Gemstones are categorised into precious and semi-precious varieties. Precious gemstones, such as sapphires, emeralds and rubies, are highly desired for their rarity and beauty. Semi-precious gemstones, including amethyst, topaz and peridot, are more abundant but equally stunning.
Natural & Synthetic
Natural gemstones are formed through geological processes over millions of years, making each stone unique. Synthetic gemstones, on the other hand, are created in laboratories to have the same chemical and physical properties as their natural counterparts. While natural gemstones are prized for their rarity and authenticity, synthetic gemstones offer a more affordable and ethically sourced alternative without compromising on beauty or quality.
Popular Choices
Among the most sought-after gemstones, sapphires, rubies, and emeralds stand out due to their timeless beauty and durability. These traditional gemstones are long-time favourites for engagement rings and heirloom pieces as an investment and statement of style.
Beyond the classic choices, many other less conventional stones like quartz and garnets also offer interesting colours and unique properties.
Lifestyle
Lifestyle and how you intend to wear the stone plays heavily into what types of gemstones are suitable. For daily wear, sapphires or rubies are reliable options. For occasional wear, it is safe to opt for gemstones that are softer or more delicate, like emeralds or opals.
Gemstone Care
Proper care is crucial to maintaining the sparkle and longevity of gemstone jewellery. Different stones have varying levels of hardness and sensitivity, which dictates how they should be cared for. As a general rule, follow these guidelines:
- Regularly clean your jewellery with a suitable method for the type of gemstone, such as soaking in lukewarm water and detergent before a gentle scrub. Certain gemstones are particularly sensitive and require more delicate care.
- Dry jewellery completely before storing
- Store each piece separately to avoid scratches.
- Avoid exposing gemstone jewellery to harsh chemicals.
Understanding the specific care requirements of each gemstone type is essential to prevent accidental damage, and to keep your jewellery looking its best for years to come.
