Frequently Asked Questions
What is a lab grown diamond solitaire necklace? +
A lab grown diamond solitaire necklace features a single lab grown diamond as the main focal point, designed to sit elegantly along the neckline. The look is clean, timeless, and centred on diamond brilliance, making it a versatile piece for daily wear and gifting.
Are lab grown diamond solitaire necklaces made with real diamonds? +
Yes. Lab grown diamonds are 100% real diamonds with the same chemical, physical, and optical properties as mined diamonds. They are created using advanced CVD or HPHT technology and offer identical sparkle and hardness.
What is the difference between a solitaire pendant and a solitaire necklace? +
A solitaire pendant typically refers to the diamond setting that hangs from a chain, while a solitaire necklace can describe a complete necklace style where the diamond is integrated as the centerpiece along the neckline. Both highlight a single diamond, but the design and placement can differ.
Which carat size is best for a solitaire diamond necklace? +
For everyday wear, 0.25 to 1 carat is a popular range for a refined look. Larger sizes create a stronger statement. The ideal carat depends on your style, neckline preference, and how prominent you want the diamond to appear.
Are Variation lab grown diamond solitaire necklaces IGI certified? +
Yes. Variation offers solitaire necklaces featuring IGI-certified lab grown diamonds, graded for cut, color, clarity, and carat weight to ensure transparency and consistent quality.
Which diamond shape is best for a solitaire necklace? +
Round diamonds are the most classic choice for maximum sparkle. Oval and pear shapes offer a more elongated look, while emerald and cushion cuts deliver a structured, elegant presence.
What chain length is best for a solitaire necklace? +
Standard necklace lengths like 16 to 18 inches are most common for solitaire styles as they sit near the collarbone and suit most necklines. Longer lengths work well for layering or a more relaxed, modern look.
Can I customise a lab grown diamond solitaire necklace? +
Yes. You can customise the diamond shape, carat weight, setting style, and chain length. Variation also supports bespoke designs using CAD/CAM for precise proportions and refined finishing.
How should I care for a lab grown diamond solitaire necklace? +
Clean with mild soap, warm water, and a soft brush, then dry with a lint-free cloth. Store it separately to avoid tangling, and periodically check the clasp and setting to keep it secure.
Do you ship lab grown diamond solitaire necklaces internationally? +
Yes. Variation ships worldwide. Each solitaire necklace is securely packaged and delivered with certification and authenticity documentation, with shipping options available across multiple international markets.
