Collection: Opal

Opal is a yet another valuable gem from the silicate mineral family, prized for its vibrant play-of-color.

The word Opal is believed to have originated from the Latin word “opalus”, which itself was derived from the Greek “opallios”, meaning “to see a change of color.”
Composed of hydrated silica, its water content ranges from 3% to 21%, giving each stone a unique, iridescent glow.

Opals are majorly found mainly in Australia, Ethiopia, and Mexico and over the centuries, have been associated with emotional healing, creativity, and luxury.
The most popular varieties of opal are include White Opal, Black Opal, Fire Opal, and Boulder Opal. If you are looking to buy opal gemstone online, check out the best opal collection available at Gemstonesforsale.

How to Wear an Opal Stone

Since wearing an opal is not just about the aesthetics but also about the healing effects it has on your body and mind, knowing how to wear an opal gemstone becomes a non-negotiable.

→ Which Finger to Wear It On:

An opal gemstone is traditionally worn on the ring finger of your dominant hand, especially in astrological practice.

Why? Because the ring finger is ruled by the sun and Venus, amplifying opal’s vibrations of love, luxury, and creativity. It allows energy flow from your hand chakra to the rest of your body.

→ Cleanse Before Wearing:

Before wearing your opal, cleanse it energetically by:

• Soaking in lukewarm water with mild soap for 10 min max.
• Leaving it under moonlight overnight
• Using sound (singing bowls) or sage to remove stagnant energies

Why? Opals are sensitive and absorb emotional frequencies just like they absorb water. Cleansing clears past imprints and aligns the stone with your energy and intention.

→ Ideal Weight (in carats):

Choose an opal that weighs approx. 1/10th of your body weight in carats.

For example, if you weigh 60 kg, a 6-carat opal is ideal.

Why? In Vedic astrology, this proportion is believed to balance energetic impact with your body’s aura — ensuring neither over-activation nor dullness.

→ Choosing the Right Color:

Go for opals with clear play-of-color and minimal internal fractures.

• White opals = peace and purity
• Black opals = transformation and power
• Fire opals = passion and vitality
• Boulder opals = grounded creativity

Why? Each opal variety has subtle energetic nuances. The color and clarity directly influence which areas of life it will support — emotional balance, prosperity, love, or creativity.

→ Best Metals for Setting:

Opals work best when set in silver, white gold, or platinum.

Why? These metals enhance Venus-aligned energy and provide a strong, non-reactive base that doesn’t disrupt the stone’s vibration.

→ Everyday Use Tips:

• Opals can be worn daily, but they are delicate (Mohs 5.5–6.5) so be a little extra cautious with them.
• Avoid direct impact, perfume, harsh chemicals, or excessive heat.
• Remove before bathing or swimming to protect the stone’s structure and color.

When to Wear an Opal

Although you can wear an opal at any hour of the day, in the Indian astrology, opal is best believed to be worn on a Friday (day of Venus in the Hindu calendar) between 5:00 am - 7:00 am of a waxing moon phase.

Before understanding the price range of opals, we need to understand what are the different qualities of opal available in the market and what factors really determine these qualities.

Broadly, opals are segregated into two main categories -

One is precious opals that show a play of color. Opals from Australia & Mexico like Black opals, Fire opals, White opals, Boulder opals & Crystal opals fall under the category of precious opals.

The other one is common opals which do not exhibit play-of-color but are still valued for their beautiful pastel shades. Opals predominantly from Peru & Oregon like Blue opals, Milk opals and Pink opals fall under the category of commons opals.

What determines the value of an opal?

Just like diamonds or any other gemstone, opals are graded based on four key factors—color, clarity, cut, and carat weight. These 4 C’s are essential for any buyer to know before making their purchase. Let’s have a deeper look.

1. Color : Color plays a very important role in determining opal values. Here’s what you should look for in opal’s case:

→ Play-of-Color: The more vibrant and varied the colors, the higher the value.

→ Background Color: The base color also called background on which the stone displays the play of color plays an important role. Usually black opals are valued the most, followed by white and then crystal opals.

→ Brightness: The intensity of the colors determines the opal’s appeal. Bright opals fetch higher prices.

2. Clarity : Generally opal doesn't come with inclusions.

→ However, since there are many different varieties of opal some types might come with inclusions such as cracks, sand or webbing. These inclusions generally tend to lower the value of an opal unless it’s an extraordinary piece that may result in an increased value than normal.

→ Boulder opal might come with natural inclusions and they are accepted as well because of the stone’s unique formation.

3. Cut : The cut of an opal plays an important role in deciding its price. Usually the round and oval cuts are most valuable and preferred. However, cuts are more of a personal preference and one should purchase what aligns with their demands.

Commonly, opals are available in -

• Cabochon Cut: Most opals are cut into smooth domes to enhance their play-of-color.
• Freeform Cut: Some opals are cut based on their natural shape to preserve maximum color.
• Faceted Cut: Rare but can add extra brilliance.

4. Carat Weight : Opals are measured in carats, but size isn’t as important as color and clarity. Large opals with vivid color are rare and expensive. However, a rich play of color is what adds life to an opal which is why one must put carat weight as the secondary characteristic when deciding to buy an opal.

Buying an opal requires more than just choosing a pretty stone.

Whether you’re shopping to buy loose opal stone for custom jewelry, or looking for ready-to-wear pieces, the opal stone price can vary based on authenticity, treatments, and origin.

Here are key factors every buyer should consider before making a purchase:

• Natural vs. Lab-Created: Always confirm whether the opal is natural or synthetic. Natural, untreated opals are more valuable and astrologically significant.
• Transparency About Treatments: Many opals undergo enhancements like sugar or smoke treatment. Reputable sellers will disclose this clearly.
• Check for Hydrophane Behavior: Ethiopian opals are often hydrophane — they absorb water and can temporarily change in appearance.
• Request Certification: A gem lab certificate such as from IGI or GIA ensures authenticity and verifies origin, treatment status, and other key features.
• Know the Seller: Buy from trusted sources with a clear return policy, genuine reviews, and detailed product listings.
• Match Use with Type: Choose durable types like fire opals or black opals for rings; delicate opals are better suited for pendants or earrings.

Many buyers prefer to buy opal gemstone online due to the transparency, better prices, access to certified loose opals for sale and above all the ability to look from different stores at the same time + return in case product doesn’t match up - all through the comfort of home.
