Why Choose a 3ct Lab Grown Diamond Ring?

FAQs

How much should I expect to pay for a 3 carat diamond?

The price of a 3 carat lab grown diamond depends on its cut, clarity and colour, as well as the setting and metal choice. Lab grown diamonds cost significantly less than mined diamonds as they can be created on demand, making a 3ct lab grown diamond ring an affordable yet luxurious option.

How long does it take to grow a 3 carat lab grown diamond?

It takes approximately 3-6 weeks to form a 3ct lab grown diamond using High Pressure High Temperature (HPHT) or Chemical Vapour Deposition (CVD) methods. This process replicates natural diamond formation, ensuring the same chemical, physical and optical properties.

Is a 3ct diamond too big for an engagement ring?

No! Although it depends on the person you’re proposing to and their personal sense of style. A 3 carat diamond is a bold and eye-catching choice for an engagement ring, and would suit those who love a bit of drama. This size of ring looks fantastic in solitaire, halo or three-stone settings, making it a versatile option for different preferences.

Do lab grown diamonds hold their value?

While natural diamonds may increase in value over time, lab grown diamonds are more affordable upfront and offer excellent value for those who prioritise size and quality. Their resale value is lower than mined diamonds, but their cost savings make them a smart purchase for buyers who want to enjoy luxury without overspending.

What is the best setting for a 3 carat diamond ring?

The best setting depends on your personal style. A solitaire setting highlights the diamond’s size and brilliance, while a halo setting enhances its sparkle. A three-stone design symbolises past, present and future, making it a thoughtful choice for engagements or anniversaries.
