FAQs For Lab-Grown Diamond Necklaces and Pendants

How to select the ideal lab-grown diamond necklaces or pendants?

To select the ideal lab-grown necklace or pendant, identify your budget and choose a preferred style and design. Pick the diamond shape and desired carat weight, and ensure diamonds are secured with a durable setting. Settle for a suitable fine metal, reliable chain type and length, and sturdy clasp. Review diamond and metal authenticity and buy only from a renowned brand with lifetime coverage and maintenance support.

What’s the best way to check the quality of lab-grown diamond necklaces or pendants?

You can verify the quality of lab-grown diamond necklaces or pendants by assessing the diamond quality (the 4 C’s). Review the metal authenticity and the chain and clasp durability. Ensure that the brand adheres to conflict-free sourcing practices and offers aftercare support and lifetime coverage.

Why choose lab-grown diamond necklaces and pendants over natural ones?

Below are the top reasons why lab-grown diamond necklaces and pendants are more desirable than mined ones.

  • Price: Lab-grown diamonds are much more pocket-friendly than natural ones while offering the same brilliance and structural integrity. This lets you choose jewelry with exceptional quality diamonds of higher carat weights while staying within your budget.
  • Quality: Lab-grown diamonds are built to match the quality of natural ones in cut, clarity, and color, and even have minimal inclusions. This makes it a great hit among value-driven buyers.
  • Ethics: Lab-grown diamonds are created in controlled environments, involving minimal to zero natural disruptions. This makes them ethical, conflict-free, and sustainable, attracting eco-conscious buyers.

How do I decide the right carat size for my lab-grown diamond necklace or pendant?

Consider your personal style and the frequency of usage. For everyday wear, a classic 0.10-1 carat minimalist pendant or necklace offers subtle elegance. If you want a more statement-worthy look or something for special occasions, larger stones or multi-stone styles up to 2-10 carats are ideal. If you’re hunting for wedding jewelry, it can be even higher.

When can I expect to receive my custom lab-grown pendant or necklace?

Your custom necklace or pendant will typically be handcrafted and delivered within 12 to 15 business days. This includes time for stone selection, design approval, fine crafting, and final quality checks before shipping.

What’s the price range for a custom lab-grown diamond necklace or pendant?

Prices start at around $280 for minimalist pendants and can go beyond $17,100 for ones with heavy diamond-crusted designs. The cost varies with the diamond size, complexity of the design, metal choice, and custom detailing.

Are design changes possible after the making of my custom lab‑grown diamond necklaces or pendants?

Since each custom piece is handcrafted to your specifications, design changes after completion are not possible. Further design modifications call for a complete remake, which requires both extra costs and time. It’s always better to finalize your design before placing the order.

Why are we a trusted choice for custom lab-grown diamond necklaces or pendants?

Each of our neckpieces is crafted with ethical stones, durable metal, and customization at every step.
