Clarity Guide
Clarity is referred to as the purity of a diamond. Almost all diamonds have small impurities or “inclusions”, even those grown in a lab, but they are not always visible to the naked eye. They are graded on a scale from (I) Included to (F) flawless.
At Ethica Diamonds, the standard for our diamonds is VVS or flawless, which are at the top of the grading scale for clarity. This is because imperfections can cause weaknesses within a diamond, making them more susceptible to chipping (yes, all diamonds can chip!) We like to ensure the diamonds we set in our jewellery have the highest chance at not doing that and staying perfect through the generations. Also, the higher the clarity grade, the better the sparkle, which is only ever a good thing.
Metal Guide
At Ethica, we make our rings in four standard metal options: 18k rose gold, 18k yellow gold, 18k white gold and platinum, from recycled origins. These metal options strike the perfect balance between luxury and durability for fine jewellery.
Colour Guide
The Gemological Institute of America (GIA) developed the diamond colour scale in the 1940s to standardise diamond colour grading internationally. The scale begins with the letter D, which represents “colourless”, ie the whitest diamond possible, and increases in colour as the scale goes down the letters to “Z”.
At Ethica, we have a standard on our website for our white diamonds, being D, E or F. However, we also have an inventory for warmer coloured diamonds that are G, H & I, which is ideal for those who are looking to explore ways to make their budget go further, or simply have a preference for a warmer colour grade.
Fancy coloured diamonds (blue, pink, yellow, green etc) do not apply to the above colour grade scale, as their colour’s extend beyond the scale. To enquire about fancy diamonds, contact us directly and we will be delighted to guide you individually, to help you find the perfect coloured diamond for you.
Carat Size Guide
Round - Timelessly Classic, the round brilliant cut diamond will always be the most popular and classic shape. It is beloved for its unmatched brilliance and beauty and it returns the most amount of light due to its ideal facet pattern. It resembles a simple circle, which makes it extremely versatile.
Oval - Flattering and elongating, oval diamonds look larger than round diamonds and creates a gentle elongating effect for which elliptical gemstones are treasured. They make a woman’s finger seem longer and more slender. It’s popularity has soared in recent years and the oval is definitely one of our top selling shapes.
This cut is particularly flattering due to it's elongated shape
Emerald Classic - “Hall of mirrors” creates exceptional clarity. The ultimate vintage cut, a classic emerald cut diamond exudes old-world glamour. Unlike the multi-faceted brilliant cuts, this step-cut diamond isn’t known for sparkle, and should be enjoyed for its lustre and clarity instead.
The sophisticated Emerald cut is a rectangular shape with flat corners. It has a step cut facet design, which resembles a deep staircase and has the refractive effect of a series of mirrors.
This cut is particularly flattering due to it's elongated shape
Pear - Also known as teardrop of joy, the Pear cut diamond has often been a favourite of royalty and is also known as the teardrop diamond. The deep, mesmerising Pear cut is a combination of the rich fullness of the Round Brilliant and the sparkling intensity of the Marquise. Though traditionally used in pendants and drop earrings, this cut is also an eye-catching addition to rings. It’s a unique, beautiful cut that looks especially good in a halo setting and is known to have a slenderising effect on fingers due to its tapered end.
This cut is particularly flattering due to it's elongated shape
Asscher - The Asscher cut diamond can be seen as a 21st-century update to the Emerald cut. Also known as a step-cut, the Asscher cut features longer facets which give it a staircase appearance. It flashes long lines of sparkle, instead of the typical all-over sparkle. This cut features a square shape with many small step cuts along the top edges, and longer facets underneath for a Hall of Mirrors effect. The Asscher cut has a facet plan that draws the eye into the gemstone, giving it depth.
Cushion - The Cushion features a similar square silhouette to the Princess cut diamond, but has rounded corners, sometimes referred to as a Pillow cut, the Cushion cut has an open culet (the bottom point of the stone) The result is a deep, luxurious gemstone with a romantic effect. This is a square diamond shape with rounded corners and 61 facets. The cushion cut is one of the most brilliant cuts of all square and rectangular shaped stones, and makes a wonderful choice when looking for a classic shape that is more unique. Elongated cushions are also a wonderful choice for diamond shape. What that means, for those who don’t know, is when the diamond is longer than is is wide. Contact us directly if you would like an elongated cushion for your jewellery.
Emerald radiant - If you’re looking for an alternative to the popular Princess cut, a Radiant cut diamond for your engagement ring makes a lovely and classic choice. This cut is perfect for those who seek a breathtaking combination of an Emerald cut whilst craving the classic sparkle of a Round Brilliant cut diamond. A relatively new diamond shape, the Radiant cut was designed by Henry Grossbard in the late 1970s. He created a cutting technique that combined the best elements of Emerald and round diamond shapes–allowing Radiant diamonds to exhibit incredible brilliance and fire. The Radiant is also the first cut to have a brilliant-facet pattern applied to both the crown & pavilion which makes it exhibit fierce shine with much more brilliance and sparkle.

Princess - The princess cut diamond is a traditionally square diamond with sharp edges and 59 facets. The cut has a square shape when viewed from above, whilst from the side it is similar to that of an inverted pyramid. Princess cut diamonds have intense sparkle and intricate cross facets making it a favourite: as of 2015, princess cut diamonds were the second most popular choice for an engagement ring.
Heart - The gentle and endearing Heart cut diamond is also one of the most scintillating jewel designs. A modified version of the classic round brilliant, its rounded pavilion gives it incredible refraction and breathtaking brilliance, while the pointed bottom and gracefully curved arches at the top complete the shape with perfect symmetry.
Marquise - Similar to Pear, the Marquise cut diamond appears the largest of all cuts. Also known as “Navette”, meaning little boat in French, due to the marquise diamond’s boat-like shape. The long shape has a flattering, slenderising effect on the fingers, due to the tapered edges on both sides. A sleek and seductive design, the perfect Marquise cut gemstone should always be cut in a 2:1 aspect ratio, meaning it must be twice as long as it is wide to have the proper aesthetic effect.

Description
The Cami trilogy engagement ring is an Art Deco inspired design that brings together glamour, structure, and refined sparkle. At its centre rests a beautifully cut pear lab grown diamond, chosen for its graceful shape and radiant brilliance. On either side, two tapered baguette cut lab grown diamonds create a balanced and striking trilogy formation, echoing the clean lines and symmetry of classic Art Deco styling. As a result, the ring delivers a look that feels both timeless and contemporary. Because the tapered side stones guide the eye inward, The Cami engagement ring naturally highlights the pear cut centre diamond. Light travels through each facet with ease, enhancing brilliance and giving the design an elegant flow.
The slim, structured band further elevates this effect, creating a harmonious silhouette that feels sophisticated without overpowering the central stone. This thoughtful shaping ensures the ring remains visually balanced while offering a bold yet refined presence. This versatile trilogy style pairs beautifully with a range of wedding bands, yet also stands confidently alone as a striking statement piece.
With its blend of geometric elegance and radiant sparkle, The Cami trilogy ring is a glamorous expression of love, artistry, and enduring style.
