 gemstone is a type of mineral that is greatly sought after for its beauty, strength, and rarity. A few non-crystalline organic elements, such as pearls, red coral, and amber, are also categorized as gemstones. Gemstones have long been utilized in jewelry. 

Colour is the most important factor when assessing the quality of coloured gemstones. Other factors affecting its value include transparency and lustre (“fire”). Some gemstones also have phenomenal characteristics that include iridescence, opalescence, asterism (the appearance of a star-shaped figure in reflected light), chatoyance (the appearance of a variable luster and a narrow, undulating band of white light), pattern, and shine. 

These days you may be able to buy some of the best custom jewellery and even a gemstone online. In fact, accessibility for choices and the convenience garnered by the digital era allow you to buy gemstones and customise them into gorgeous bespoke pieces without hassle or unaffordable price tags. 

Here are a few trending gemstones that people often choose for customising their own jewelries.


Aquamarine, a gemstone that features the hue of the sea on a hot tropical vacation or a chilly iceberg in the Antarctic, is affordable, gorgeous, and wearable — it can withstand a few knocks without cracking or scratching. 

Aquamarine is a beryl variation that ranges from greenish blue to bluish green in colour. Iron impurities within colourless beryl give it its blue hue. The more valuable aquamarine is, the darker the blue colour, but it is usually relatively light. 

Heat treatment is used to bring out the blue tones, yet the process is unnoticeable and very stable. It is the ideal colour to incorporate in spring as the birthstone for March, and it is a popular supplementary addition to fashionable trends.

What has been said about this stone?

Aquamarine represents youth, love, and hope. Aquamarine is considered a useful stone for all types of teachers and speakers. It brings speakers to a state of awareness in which they are fully aware of their truth, wisdom, and feelings, and can articulate them clearly and convincingly. It is also thought to enable you to speak effectively and calmly during tense situations.


The purity of a diamond is affected by its natural formation, as well as the mining and polishing operations. No two diamonds are indeed alike, and the clear properties of a diamond work like a fingerprint. One of the most well-known and sought-after gems for jewels is the diamond. They have been used as decorative ornaments since ancient times.

The superior durability and unmistakable aesthetic of diamond — which gives it its distinctive “fire” — make it appealing for jewelry. Diamonds are such a popular gem that various organizations have sprung up to grade and certify them based on the “four Cs,” or color, cut, clarity, and carat weight. 

Other features, such as the presence or absence of fluorescence, influence the desirability and consequently the value of a diamond used in jewelry. 

Most engagement rings are made of diamonds, but coloured gemstones have gained popularity and are now the preferred choice for many. 

There are a handful of gemstones that have historically been used as engagement or proposal rings, including Sapphire, Ruby, Emerald, Spinels, Tanzanite, and Tourmalines.


Emerald is a green to greenish-blue variation of the beryl family gemstone that forms over hundreds of millions of years in igneous, metamorphic, and sedimentary rocks under high heat and pressure. Beryllium, aluminum, silicon, and oxygen are the four elements that make up an emerald. The inclusion of chromium, vanadium, or iron in emeralds gives them their green color. 

The most valuable emeralds are pure green with vibrant vibrancy and no noticeable color changes across the stone. Colour of Emeralds can range from bluish green to slightly yellowish green. Too much yellow or a green that is not saturated enough will not qualify the Beryl as an Emerald, instead, it is known as the green beryl. 

Due to its high heat and high pressure environment, Emeralds are nearly always found with eye visible inclusions. Hence, buying one with a high clarity and few inclusions will command a premium. 

You’d read many articles citing Emeralds from Columbia as the better ones. But Zambia is equally capable of producing top fine quality Emeralds too. Be it Columbian Emeralds or Zambian Emeralds, it is important to view the Emerald in person and see its colour, clarity and glow for yourself. At the end of the day, colour preference is personal. 


Gem-quality garnets come in every colour, with red garnets being the most frequent and blue garnets being extremely rare.

Because it is abundant and affordable, red almandine is the most commonly used red garnet in jewelry. For the same reason, reddish garnets like pyrope and spessartine are widely found in jewelry. 

Other variables include the Demantoid Garnet and the Tsavorite Garnet. Green demantoid garnet has grown fashionable in recent decades. It has a higher dispersion than diamonds, which means it has more “fire” than diamonds.

The hue of green tsavorite is vivid and rich, similar to emeralds. It is frequently used as a substitute for emerald. Both of these green garnets are becoming increasingly popular, but they are far more expensive than almandine garnets.

Tsavorites have become popular as an alternative to Emerald. Tsavorites are more expensive than other Garnet species, however a good quality Tsavorite can be a fraction of the price of an Emerald. It’s simple to see why so many people prefer this option being one of the oldest forming gemstones available. 

Its high refractive index and dispersion levels translate to stunning brilliance, and it is significantly less expensive than certain gemstone options, while its gorgeous, pure green colours, as well as durability, purity, and rarity draws gem collectors and jewellery enthusiasts alike.


While Sapphires are most commonly associated with blue corundum, the corundum species is available in other colours such as green, white, orange, purple, pink, and yellow sapphires. The other colours are known as fancy Sapphires.  A red corundum, on the other hand, is known as a ruby. 

A sapphire’s worth is mostly determined by its colour, with deep, vivid royal blue sapphires being among the most valuable. The colour of a sapphire can be a huge spectrum. Some of the more popular colours include twilight blue sapphire, peacock blue sapphire, cornflower blue sapphire, velvet blue sapphire, and royal blue sapphire.

The rarest form of corundum is known as the Padparadscha. They are highly coveted for its unique mix of orange and pink colours, likening them to sunset, lotus flower or salmon. 

It’s also a royal gemstone, with many people believing it represents abundance and clarity. Sapphire is a popular gemstone alternative to diamonds in bridal jewellery because of its brilliance and durability, which are comparable to diamonds.


Tanzanite is a relatively new gemstone that can only be found in one location on the planet. This blue-violet zoisite fragment was named after Tanzania by Tiffany & Co, where it was first discovered in 1967. 

For the most part, this option exists in a spectrum of hue from violetish blue to bluish violet based on how much weight is maintained from the rough cut since the crystals reveal varied colours.

Tanzanite has quickly gained popularity among jewellers and gem collectors. The translucent zoisite gets a stable, gorgeous blue to violet colour with heat treatments, while being normally reddish brown.

Tanzanite, along with zircon, turquoise, and blue topaz, are December birthstones. It is also the gemstone of choice for a 24th wedding anniversary, and a popular alternative to Sapphires.


The magnificent species of Tourmaline is distinguished by its wide variety of varieties, shapes, and forms. It usually develops in beautiful long hexagonal ‘pencils’ within the host rock, and it has an exquisite prismatic crystal habit. 

Its name comes from the Sinhalese words ‘tura mali,’ which means mixed-color stone.’ Tourmaline is dichroic, which means it may change colour subtly depending on the light source as it shifts from natural to artificial.

Due to its pure beauty and rarity, the Paraiba tourmaline, the rarest of the derivatives, is a highly sought-after gemstone. A Paraiba tourmaline’s ‘swimming-pool-blue’ genuinely shines with vivacity, clearly standing out against many other gemstone choices.

Because the exquisite cupriferous tourmaline crystals from Paraiba’s “noble hill” were practically all fragments when they were discovered, Paraiba tourmalines are almost usually small. 

There are so many options when it comes to gemstones that you may be spoilt for choice. Either way, the customising of gemstones has quickly become a popular approach to crafting unique and personalised pieces for the perfect occasion.
