Are laboratory-grown diamonds real diamonds?
Yes. Laboratory-grown diamonds have essentially the same chemical composition, crystal structure, optical properties and physical properties as natural diamonds. They are not simulants such as cubic zirconia or moissanite. Their origin must still be clearly disclosed.
Can you tell a laboratory-grown diamond from a natural diamond by looking?
Reliable origin identification generally requires appropriate laboratory testing or specialized screening equipment. Laboratory-grown diamonds have growth features and trace characteristics that trained laboratories can detect, even when the stones appear the same in ordinary viewing.
Do laboratory-grown diamonds hold their value?
Plan conservatively. Laboratory-grown diamond prices have experienced substantial downward pressure as production expanded, and the secondary market remains limited. A stone purchased today may cost considerably less to replace later. We generally recommend assuming very little recoverable value.
Do natural diamonds hold their value?
Natural diamonds have a more established secondary market and generally stronger future-value potential than laboratory-grown diamonds, but they should not automatically be treated as investments. Resale value is often below original retail price and depends on quality, desirability, documentation and market conditions.
Which is better for an engagement ring?
Neither is universally better. Laboratory-grown is often better when visible size and specifications within a fixed engagement-ring budget matter most. Natural is often better when rarity, geological origin, heirloom intent or stronger future-value potential matters more.
What is the Diamond Table?
The Diamond Table is the part of the private consultation where loose natural and laboratory-grown diamonds are placed side by side so you can compare shapes, cut quality, proportions, appearance and price in person and under magnification.
Are laboratory-grown diamonds graded?
Yes. Independent laboratories evaluate laboratory-grown diamonds and clearly identify their origin. Report formats and terminology vary by laboratory, and those standards can change over time, so we explain the specific report accompanying each diamond rather than pretending every document is identical.
How are laboratory-grown diamonds made?
They are produced primarily through HPHT, high pressure and high temperature, or CVD, chemical vapor deposition. Both methods grow diamond material around a seed in controlled conditions.
Do laboratory-grown diamonds become cloudy or change over time?
No. Normal aging does not cause a laboratory-grown diamond to become cloudy or lose its fundamental diamond properties. As with natural diamonds, surface oils, lotion and everyday wear can make the stone appear dull until it is cleaned.
Are laboratory-grown diamonds more ethical or sustainable?
They avoid some concerns associated with mining, which matters to many clients. Their production also requires energy, and environmental impact varies according to the energy source and manufacturing process. Natural-diamond supply chains also vary. Broad claims that either category is automatically impact-free deserve careful scrutiny.
Can I insure a laboratory-grown diamond?
Yes. Laboratory-grown diamond jewelry can generally be insured. Because replacement prices may change, ask your insurer how the policy determines replacement value and how often the appraisal should be updated.
Do you keep both natural and laboratory-grown diamonds available?
We maintain a working selection and source diamonds specifically for each consultation. Sharing your budget, preferred shape and approximate size beforehand allows the Diamond Table to be prepared with options that are actually relevant to you.
