FAQs

What types of opal are available in the 2-5 carat range?

You can find several opal varieties in this size range, including Ethiopian Welo Opal, Australian White Opal, Black Opal, and Fire Opal. Each has distinct visual properties and origin-based value differences.

Are 2-5 carat Opal gemstones suitable for jewelry?

Yes, they are ideal for pendants, earrings, and low-impact rings. However, due to opal’s relative softness (Mohs 5.5–6.5), protective settings are recommended for daily-wear pieces.

Do Opals in this size range display strong play-of-color?

Most natural opals between 2 and 5 carats do exhibit noticeable play-of-color, especially Ethiopian and Australian varieties. The intensity depends on the type, quality, and cut of the stone.

What shapes are most commonly available?

Oval is the most prevalent shape, but you’ll also find rounds, pears, cushions, and freeform cabochons. Some opals are cut to maximize color play rather than symmetry.

What is the typical price range for 2-5 carat Opals?

Prices can vary widely—from around $30 to over $500 per carat—based on origin, type, brightness of color play, and body tone. Black Opals and high-grade Ethiopian Opals are on the higher end.

Are all 2-5 carat Opals sold untreated?

Many opals are untreated, especially high-grade specimens. However, some may be stabilized or treated to improve durability or appearance. Reputable sellers like GemSelect disclose any treatments clearly.

How can I verify if a 2-5 carat Opal is natural?

Look for certification from a trusted gemological source. Natural opals should also have a unique internal pattern and no uniform color zones, which can indicate synthetics or imitations.

Do larger opals (over 2 carats) have better color patterns?

Not always. While larger opals may offer more surface for color play, quality still depends on the specific internal structure and orientation. Smaller stones can sometimes display more vivid flashes.

GemSelect Certified Store Reviews

GemSelect: Over 22 Years in the Gemstone Business! Thank you for trusting us with your purchase!

Overall Rating -> 10 star ratings

I've made several purchases through GemSelect in the past, although not within the last six months. Their gems are always beautiful and I have never had an issue with their prices or their stones. Even when I'm not buying, I love scrolling through their website, which is very user friendly. I especially appreciate being able to change the listing order to your own liking, such as most to least expensive, largest to smallest, etc. As with most online orders, however, I think the shipping charges are not commensurate with the actual weight of the items shipped.
