Diamond stud earrings are a timeless treasure. When set in 18 carat white gold, their brilliance is elevated to a level of refined luxury. Elegant yet practical, these earrings are adored by collectors, brides, professionals, and fashion lovers alike. But how much do 18 carat white gold diamond stud earrings cost?
Understanding the price of these earrings requires more than just glancing at a tag. It’s about knowing the quality of the diamonds, the purity of the gold, and the prestige of the design. In this guide, we break it all down for you in simple, beautiful detail.
What Does 18 Carat White Gold Mean?
Understanding Gold Purity
Gold purity is measured in carats. Pure gold is 24 carats, which means it contains 100% gold. However, pure gold is soft and not ideal for jewelry. That’s why it’s mixed with other metals to create an alloy.
18 carat gold contains 75% pure gold and 25% other metals. In the case of white gold, these added metals typically include palladium, silver, or nickel. These give white gold its cooler, silvery tone.
Why Choose 18 Carat White Gold?
18 carat white gold is considered luxurious. It has a richer, warmer undertone than 14 carat gold, and it holds diamonds securely due to its density. Compared to platinum, it’s lighter and often more affordable. When paired with diamonds, 18 carat white gold adds elegance without overpowering the gem.
Diamond Quality Basics
The 4Cs of Diamonds
The price of diamond stud earrings largely depends on the quality of the diamonds. These are judged using the 4Cs:
Carat Weight: Size of the diamond.
Cut: How well the diamond reflects light.
Color: How colorless the diamond is.
Clarity: Absence of internal or external flaws.
Each of these factors dramatically affects the cost.
Matching Diamonds for Earrings
For earrings, it’s important to match the two diamonds as closely as possible. A pair must have similar size, cut, color, and clarity. This adds to the cost since matching stones require careful selection and possibly custom work.
Price Range for 18 Carat White Gold Diamond Stud Earrings
The price range is wide. You can find simple pairs for under $1,000 and luxury pairs costing over $20,000. Here’s how prices break down based on diamond size and quality.
Small Diamond Studs (0.25 – 0.50 Carats Total Weight)
Typical Price: $400 – $1,200
Ideal For: Everyday wear, gifting, teens, or second piercings
Example: A pair with 0.50 carats total weight (0.25 carat each), G-H color, SI1 clarity in 18k white gold may cost $800 to $1,000.
Medium Diamond Studs (0.75 – 1.00 Carats Total Weight)
Typical Price: $1,500 – $3,500
Ideal For: Weddings, anniversaries, milestone birthdays
Example: A 1.00 carat total weight (0.50 carat each), H color, VS2 clarity, excellent cut in 18k white gold will likely fall around $2,500 to $3,000.
Large Diamond Studs (1.50 – 2.00+ Carats Total Weight)
Typical Price: $4,000 – $20,000+
Ideal For: Luxury jewelry collectors, high-end fashion statements
Example: A pair of 1.00 carat diamonds (2.00 ctw), F color, VS1 clarity, ideal cut, in 18k white gold could range from $10,000 to $18,000 depending on the brand and certification.
Cost Breakdown: Diamond vs. Setting
Diamond Cost
Diamonds account for about 80–90% of the total cost. A 0.50 carat diamond might cost $1,000, but a 1.00 carat diamond with higher quality could cost $5,000 or more.
18K White Gold Setting Cost
The setting cost includes the craftsmanship and weight of the gold. While 18k white gold is not as expensive as platinum, it still adds a few hundred dollars to the final price.
Standard Basket Setting: $150 – $400
Designer or Custom Setting: $500 – $2,000+
Halo or Vintage Style Settings: Additional costs depending on accent stones
Certified vs. Non-Certified Diamonds
Certified Diamonds
Certified diamonds come with a grading report from labs like GIA, IGI, or AGS. These provide trustworthy data on the 4Cs.
Pro: You know exactly what you’re buying.
Con: Certified diamonds may be 10–20% more expensive than non-certified ones.
Non-Certified Diamonds
Often found in mass-produced earrings, these may be less expensive but riskier in terms of true quality. Not ideal for investment pieces or high-end gifts.
Lab-Grown vs. Natural Diamonds
Lab-Grown Diamonds
Lower Cost: 30%–70% less expensive than natural diamonds
Same Beauty: Optically and chemically identical to mined diamonds
Sustainable: Environmentally conscious option
For example, a 1.00 ctw pair of lab-grown diamonds in 18k white gold may cost $1,200 instead of $3,000.
Natural Diamonds
Higher Value Retention
Prestige: Often preferred for heirlooms
Limited Supply: Hence higher prices
Choose based on personal preference and purpose—style or investment.

Custom Earrings
Design your own: choose the carat, setting style, and even metal finish.
Price Range: $1,200 – $15,000+
Pros: Unique to you, personal craftsmanship
Cons: Longer delivery time, potentially higher cost
Important Factors That Affect Price
Metal Weight and Workmanship
A thicker, more durable setting uses more gold and therefore costs more. Artisan design, handcrafting, and polish quality also add to the price.
Country of Origin
Gold and diamonds may be more or less expensive depending on where you are. European brands may charge more due to taxes, regulations, or design heritage.
Certification and Warranty
Pieces with lifetime warranties, buy-back programs, and certification carry more value.
Practical Buying Tips
Always Compare
Use online diamond comparison tools to check prices per carat across similar clarity and color grades.
Go Slightly Below Whole Numbers
Diamonds at 0.90 carats are often 20% cheaper than full 1.00 carat stones—with little visual difference.
Consider Lab-Grown Options
If you’re shopping on a budget, you can get significantly larger or clearer stones for the same price.
Buy Certified
Always request certification—especially for diamonds over 0.50 carats.
Insure Your Investment
Fine jewelry should be insured. Some retailers offer in-house plans, or you can go through your home insurance provider.
