In the world of fine jewellery, diamonds, sapphires, rubies, and emeralds have long been the undisputed favourites. Yet beyond these “big four,” there is a wealth of rare and captivating gems waiting to be discovered. Today, more collectors, designers, and couples are turning their attention to underrated gemstones — treasures that combine beauty, rarity, and individuality. Among them, spinel has emerged as a star, admired for its brilliance and versatility.
At Prins & Prins, Cape Town’s heritage jeweller, we celebrate both the timeless classics and these lesser-known gems, offering our clients the opportunity to explore jewels that are as distinctive as the stories they tell.
Why Spinel Stands Out

Spinel has a fascinating history. For centuries, it was mistaken for ruby and sapphire, even featuring in some of the world’s most famous crowns and regalia. The “Black Prince’s Ruby” in the British Imperial State Crown, for example, is actually a magnificent red spinel.
What makes spinel so special is its combination of beauty and durability. With colours ranging from vivid reds and pinks to blues, violets, and greys, spinel rivals the brilliance of more famous gems. Unlike many gemstones, it often requires little or no treatment, ensuring its natural beauty shines through.
Collectors prize spinel for its rarity, and modern jewellery lovers are drawn to its vibrant hues and distinctive charm. Its versatility makes it a superb choice for engagement rings, pendants, or statement pieces.
Other Underrated Gemstones Worth Discovering

Spinel is not the only gem enjoying a resurgence. Several other underrated jewels are capturing the imagination of collectors and connoisseurs alike:
- Chrysoberyl: Known for its golden tones and its rare cat’s-eye variety, chrysoberyl is both striking and durable.
- Tourmaline: A gem of many colours, from deep pink rubellite to blue-green indicolite, and the electrifying paraiba tourmaline prized for its neon glow.
- Garnet: Far more than its traditional red variety, garnet includes tsavorite (a brilliant green), spessartite (a fiery orange), and demantoid (renowned for its diamond-like brilliance).
These gems stand apart for their individuality. They are rarer than many realise, often more affordable than the “big four,” and lend themselves beautifully to bespoke designs.
Why Choose Underrated Gems?

The rising popularity of spinel and other underrated gemstones reflects a growing desire for individuality. Couples and collectors increasingly want jewels that stand out — treasures that reflect their personality and taste, rather than following tradition alone.
- Individuality: Each gem has unique colours and characteristics.
- Rarity: Many underrated gems are harder to source than diamonds.
- Symbolism: Like the classics, these gems carry deep cultural and emotional meanings.
- Value: They often offer exceptional beauty and rarity at more accessible prices.
Choosing such gems is about more than value; it is about creating a jewel that feels personal and distinctive.
