Thessa Diamond Necklace Brilliant - 17.5ct

Everything you need to know about gold in jewelry

At Verde Diamonds, it's all about quality and timeless beauty. That's why we exclusively work with 14 karat and 18 karat gold – the perfect balance between luxury, durability, and comfort.

What does karat mean for gold?

Karat indicates how much pure gold is in an alloy:

• 24 karat = 100% pure gold (too soft for jewelry)
• 18 karat = 75% gold + 25% other metals
• 14 karat = 58.5% gold + 41.5% other metals

Why do we choose 14kt and 18kt? Because these alloys are strong enough for daily wear, yet they retain that rich, warm appearance of real gold. Perfect for rings, bracelets, necklaces, and earrings that last for generations.

The different colors of gold

Gold is versatile. By mixing it with other metals, beautiful shades are created:

• Yellow gold – Classic and timeless, the warm color everyone knows.
• White gold – Modern and elegant, often finished with rhodium for extra shine.
• Rose gold – Romantic and refined, with a subtle pink hue due to copper in the alloy.

At Verde Diamonds, you will find all three colors – so your jewelry always matches your style.

Why gold?

Gold is not only beautiful, it is also a smart choice:

• Always retains its intrinsic value
• Globally recognized and tradable
• Jewelry can last for generations

A gold piece of jewelry is therefore more than an ornament – it is a piece of security and an investment that retains its value.

Choosing the right size is important. You want to avoid your ring being too tight or too loose, and the same goes for bracelets. Additionally, you can wear a necklace in different ways, so it's also important to determine which size suits you best.

To help you with this, we have put together size charts. However, if you are still unsure afterwards, you can always choose (when ordering an item, under the size filter) to order a ring sizer or bracelet sizer. We will send it to you first, and then you can provide us with your exact size. We will then ensure that your ring or bracelet is made to the correct size. When you proceed with the order, you do not have to pay for this ring or bracelet sizer.

Ring size chart (EU - US - UK - Diameter)

Average ring size for women in NL:

• Ring size: around 53-56 mm circumference (diameter ± 17-18 mm).
• This corresponds to EU size 17–18 and US size 7–8.

How should a ring fit?

• Not too tight, not too loose
  A ring should slide smoothly over your knuckle, but not so loose that it easily falls off.
  • If you can turn it without effort, but it doesn't slip off by itself, it fits well.
• Knuckle is decisive
  Often your knuckle is slightly thicker than the base of your finger. The ring should be able to pass over it without pain, but not too loosely.

Heat and cold:

• Warm fingers = slightly thicker
  In warm conditions (summer, exercise) your fingers swell.
• Cold fingers = slightly thinner
  In cold conditions they shrink.
  Therefore: measure your size at a neutral time, not immediately after exercise or in the cold.

Bracelet size chart

Average bracelet size for women in NL:

• Wrist circumference: average 16 cm.
• Bracelet size: 7-8 inches or 18–20 cm (wrist circumference + 0.5–2.5 cm for comfort).

How should a bracelet fit?

• Comfortable, not constricting
  A bracelet should be loose enough to move freely, but not so loose that it slides off your wrist.
• Slack is important
  Usually, you add 1.3 cm to 2 cm to your wrist circumference for a comfortable fit.
  • Tight fit: +0.5 - 1 cm
  • Regular fit: + 1 - 1.5 cm
  • Loose fit: +1.5 - 2 cm

• For daily wear: a regular fit (+1 cm) is ideal.
• For heavy bracelets or bangles: 1.5-2.5cm a little more slack, so they don't constrict.
• For adjustable bracelets: can be slightly tighter, as you can adjust it.
• Do not go more than 2.5 cm larger than your wrist circumference, as you risk your bracelet slipping off.

Just like with rings:

• Warm days: wrist can swell slightly.
• Cold days: wrist shrinks.
  So, measure at a neutral time.

Necklace size chart

How should a necklace fit?

• Not too tight, not too loose
  A necklace should fall comfortably in the desired place (neck, collarbone, chest), without constricting.
• Slack is important
  For a natural look, add about 2.5 cm (1 inch) to your neck circumference.
• Consider style:
  • Choker: 14–16 inches (tight around the neck)
  • Princess: 18 inches (classic, on the collarbone)
  • Matinee: 20 inches (just below the collarbone)

Heat and movement

• In warm weather, your skin may expand slightly, so measure at a neutral time.
• For a choker: measure tightly, but add 1 inch for comfort.

Everything you need to know about lab-grown diamonds and carats

At Verde Diamonds, we make no compromises. We only select diamonds that meet the highest standards:

• Color: Always in the most beautiful spectrum – F (colorless and brilliant), D or E also available on request.
• Clarity: Standard VS1, but VVS or F are also available on request.
• Cut: Perfectly cut according to the Hearts & Arrows principle for round shapes and excellent for all others for maximum brilliance.
• Certification: Every diamond above 1 carat comes with an official IGI certificate.
• Proportions: Always optimal depth and dimensions for the most beautiful light reflection.
  
  

See below for a detailed explanation of the well-known 4 C's (carat, color, clarity & cut).

1. Carat - Weight and points

Carat determines the weight of a diamond.

1 Carat = 0.2 grams = 100 points
A 0.50 ct diamond is also called 50 points.

For rings, earrings, and necklaces, the carat weight impacts the appearance; the more carats, the more striking, the fewer, the more subtle. This is always a personal preference.

It is important to remember: a well-cut 0.50 ct diamond can sparkle more than a poorly cut 1.00 ct diamond. That is why with us, you always get the best cut for the most brilliance.

2. Color - Why you prefer DEF

Diamonds are graded from D (colorless) to Z (light yellow).

Why is it important for jewelry?

For rings, bracelets, necklaces, and earrings, a DEF color provides the clearest and most luxurious appearance. This is unparalleled. 

3. Clarity - How much do you see with the naked eye?

The diamonds we use have the ideal balance between price and quality. 

4. Cut - The key to brilliance

The cut is often underestimated, even though it determines what we find beautiful about diamonds. It is the cut that makes or breaks a diamond.

The so-called cut is the most important aspect of a diamond and determines the extent to which your diamond sparkles or is a dull stone. 

At Verde Diamonds, every diamond is an Excellent cut (or Hearts&Arrows for brilliant cuts) and thus cut to perfection for maximum brilliance. 

FAQ - Frequently Asked Questions

1. What is the difference between lab-grown and natural diamonds?
   Physically, there is no difference. They have exactly the same chemical and optical properties. So what is different? One comes from the earth and the other from a diamond lab.
   
   
2. How do I choose the right carat / diamond?
   With us, you are guaranteed to get the best diamonds; the size of the stone and the shape are personal choices. 
   
   
3. Do I get a certificate with my diamond?
   Yes, for diamonds above 1ct, unless otherwise specified, you will receive a certificate from the IGI or GIA institute. 
   
   
4. Do my diamonds retain their value?
   When you sell a diamond, whether earth-mined or lab-grown, it will always be worth less than when you bought it. However, given the large difference in purchase price, despite the lower residual value of the lab-grown diamond, it will still have been cheaper, so you are better off with a lab-grown than an earth-mined diamond.  
   
   
5. How do I know for sure that my diamond is good?
   We only select diamonds with F color, Hearts & Arrows (excellent) cut, and VS1 clarity. This ensures that you have a diamond that sparkles maximally and belongs to the absolute top in terms of optics and color.

Choosing the right size is important. You want to avoid your ring being too tight or too loose, and the same goes for bracelets. Additionally, you can wear a necklace in different ways, so it's also important to determine which size suits you best.

This way you don't pay too much

• Direct from workshop to consumer – no wholesaler or extra retail layer
• No overstock – we make to order, so no costs for large inventories
• Own design & production – short chain, controlled quality

How do we calculate?
You save = Estimated price at jeweler – Our price
This saving varies per model, type of metal, and stone specifications.

Quality without compromise
We work with precious metals and stones of controlled origin and custom-make each piece of jewelry in our own workshop. This way, we combine workshop quality with transparent prices.

Why do we show an estimated price?
At Verde Diamonds, we design and produce ourselves and work to order. This allows us to skip expensive inventories and deliver directly to you — without a wholesaler or retail layer.
The estimated price is what this model would approximately cost at a traditional jeweler, based on common margins and current material/stone costs.

What is the estimate based on?
Material costs (gold/platinum) and diamond/gemstones of comparable quality

• Common retail margins at jewelers
• Costs for retail space and inventory risk

Please note: this is an indication. Prices vary by brand, store, and region and fluctuate with precious metal and diamond prices.
