Amethyst is a beautiful and affordable gemstone. It belongs to the quartz family and is well known for its rich purple color. Many people love amethyst for its deep hues and affordability compared to other gemstones like sapphire or ruby.
If you are wondering how much a 4-carat amethyst is worth, the answer depends on several factors. These include color, clarity, cut, origin, and market demand. In this guide, we will break down everything you need to know about the value of a 4-carat amethyst.
What Is Amethyst?
Amethyst is a variety of quartz that gets its purple color from iron and natural radiation. It has a hardness of 7 on the Mohs scale, making it durable for jewelry. The finest amethysts come in deep violet and reddish-purple shades.
Historically, amethyst was considered a precious gemstone, just like diamonds, rubies, and emeralds. However, large deposits were later discovered, making it more affordable today. Despite this, high-quality amethyst still holds value in the jewelry market.
Factors That Affect Amethyst Value
1. Color
Color is the most important factor in determining the value of an amethyst. The finest amethyst has a rich, deep purple color with hints of red or blue. Lighter or faded stones are less valuable.
- Deep purple with red flashes – Most valuable
- Medium purple – Moderately valuable
- Pale or lavender – Least valuable
A 4-carat amethyst with an intense purple hue will be worth more than a lighter-colored one.
2. Clarity
Clarity refers to the number of visible inclusions in the stone. High-quality amethyst is usually eye-clean, meaning it has no visible flaws.
- Flawless or eye-clean stones – More valuable
- Visible inclusions or cloudiness – Less valuable
A 4-carat amethyst with no visible flaws will be more desirable than one with inclusions.
3. Cut
Cut affects both the beauty and value of an amethyst. Well-cut stones reflect light better and appear more brilliant.
Popular cuts include:
- Round, oval, cushion – Most valuable
- Emerald or step-cut – Less brilliance, but elegant
- Cabochon (smooth, rounded cut) – Usually lower value unless the stone is high quality
A poorly cut amethyst may look dull and be worth less, even if it has good color.
4. Carat Weight
The larger the amethyst, the more valuable it is per carat. However, because amethyst is abundant, even a 4-carat stone is still affordable compared to other gems.
The price per carat may increase slightly for larger stones, but the difference is not as dramatic as with rarer gemstones.
5. Origin
The origin of an amethyst can influence its value. Some locations produce higher-quality stones.
- Siberian amethyst – Deep purple with red flashes, most valuable
- Uruguayan amethyst – Rich purple, high quality
- Brazilian amethyst – Lighter in color, more affordable
- African amethyst – Can be very dark, sometimes almost black
Siberian and Uruguayan amethysts often command higher prices than Brazilian stones.
How Much Is a 4-Carat Amethyst Worth?
The price of a 4-carat amethyst varies depending on the factors above.
On average, here are some price estimates:
Low-quality (light color, visible inclusions, poor cut): $5–$15 per carat
Medium quality (good color, minor inclusions, decent cut): $15–$50 per carat
High quality (deep purple, no visible inclusions, excellent cut): $50–$200 per carat
A 4-carat amethyst can range from $20 to $800, depending on quality.
How Amethyst Compares to Other Gemstones
Amethyst is much more affordable than many other gemstones.
Here’s a comparison of similar-sized stones:
4-carat amethyst: $20–$800
4-carat sapphire: $1,000–$10,000+
