Large Carat Fine Jewellery

Sometimes bigger really is better, you don’t need to let your budget compromise your dream engagement ring. With our ethical stone options we can create large carat rings at an affordable price, that are just as durable and beautiful as mined diamond.

Diamonds are measured in carats, which refers to the weight rather than the actual size of a diamond. This means that the larger the carat, the heavier the diamond will be.

More people want larger carat stones in their jewellery these days and with every celebrity engagement being documented and shared online, everyday people aspire to a bit of celebrity glam, without the cost of a mined diamond.

A large mined diamond with a nice colour and good clarity (let’s say 3.0ct) would set you back at least £60,000. Our lab grown diamonds, not only have the ethical benefits, but cost a fraction of the price too. They have exactly the same composition as natural diamonds, just without the human and environmental toll that comes from diamond mining practices.

Our Signature gemstone, the Ethica Diamond®, perfectly imitates the finest diamonds. Precisely cut from premium grade silicone carbide (moissanite) with a diamond infusion and independently certified, they are visually indistinguishable from diamond, even to many jewellers and are also more cost effective than lab grown diamonds.

Frequently Asked Questions

Do your diamonds and gemstones come with a certificate?

Diamond certificates help authenticate a diamond’s characteristics for quality and pricing purposes and a certified diamond is very important to a consumer, because without one, is much like buying a car without a warranty.

The Ethica Diamond is certified by the both the IGI and GRI, both using international standards, and all of our lab diamonds are certified by a mixture of bodies, including IGI, GCAL, GIA.

Can I get a bigger carat weight if I choose moissanite?

Yes, you will be able to get a bigger carat weight if you choose moissanite over a diamond. Moissanite is a lab-created gemstone that is known for its affordability compared to diamonds, so you can typically get a larger stone for the same price as a smaller diamond. This means that if carat weight is important to you, choosing moissanite may allow you to get a bigger stone within your budget. The Ethica Diamond® is our signature gemstone, which is a premium grade D-E VVS1 independently graded moissanite and this beautiful gemstone is a lot more affordable on the larger carat options compared to diamond.

At what carat size does a diamond look fake?

There is no specific carat size at which a diamond will look "fake." The perceived authenticity and quality of a diamond depend on various factors, including its cut, colour, clarity, how well it is set in a piece of jewellery and also how well the wearer carries it off! However, it is worth mentioning that extremely large diamonds, typically above 5 carats, may raise suspicions due to their rarity and high cost, particularly if they are natural diamonds. In the end, it is a matter of personal preference and individual perception. Bigger diamonds in jewellery are now more accessibly priced than ever before and so many people like to recreate a bespoke piece of diamond jewellery inspired from a celebrity or high profile person.

why are lab diamonds cheaper than natural ones?

Lab diamonds are cheaper than natural ones primarily because of their production process. Natural diamonds take millions of years to form deep within the Earth's mantle and then require extensive mining operations to extract them. This entire process is time-consuming and costly, not to mention environmentally damaging.

On the other hand, lab diamonds are created in a controlled environment in a lab setting. They are grown using advanced technological processes that simulate the conditions under which natural diamonds are formed. This synthetic process allows for a more efficient and predictable production of diamonds, which reduces the overall cost of production.

It is also important to note that not all lab grown diamonds are sustainable just because they are not naturally mined. You can read more here about sustainably grown diamonds.

Additionally, lab diamonds do not require expensive mining operations, which can be harmful to the environment. This further reduces their cost compared to natural diamonds.

Overall, the combination of an optimized production process and the elimination of mining costs allows lab diamonds to be produced at a lower cost, making them more affordable for consumers.

Are celebrity engagement rings too big?

Celebrity engagement rings can vary greatly in size, and what is considered "too big" ultimately depends on personal preferences and societal norms. Some celebrities may opt for extravagant and large engagement rings that showcase their wealth and status, while others may prefer more modest and understated designs.

In recent years, there has been a trend towards larger and more elaborate engagement rings among celebrities. However, there is no hard and fast rule about what size is considered "too big." It ultimately comes down to personal taste and what the couple deems appropriate for their relationship and lifestyle.

At Ethica, we can create a bespoke celebrity inspired engagement ring for you if you have a specific design in mind.
