How to Choose the Perfect Engagement Ring: The Complete Guide 2026
Choosing an engagement ring is one of the most exciting and meaningful purchases you will ever make. But with so many styles, diamond shapes, metals and settings to choose from, the process can feel overwhelming.
In this complete guide, we walk you through everything you need to know to choose the perfect engagement ring with confidence.
Step 1 - Set Your Budget
Before you start browsing, it is important to have a clear budget in mind. The old rule of spending two months salary on an engagement ring is completely outdated. The right budget is whatever feels comfortable for you.
With lab grown diamonds, your budget goes significantly further. A stunning 3ct oval lab grown diamond engagement ring can cost the same as a 1ct natural diamond ring — giving you maximum beauty for your money.
A good starting point for most couples shopping for lab grown diamond engagement rings is between $1,000 and $3,000 though we have beautiful options at every price point.
Step 2 - Choose Your Diamond Shape
The diamond shape is the most visible and personal aspect of an engagement ring. Here are the most popular shapes and what makes each one special:
Oval Cut The oval cut is currently the most popular engagement ring shape. Its elongated silhouette makes the finger look longer and slimmer, and it appears larger than a round diamond of the same carat weight. The oval cut delivers exceptional brilliance and fire.
Round Brilliant The classic round brilliant cut has been the most popular diamond shape for decades. With 58 precisely calculated facets, it delivers unmatched sparkle and brilliance. It is the most versatile shape and suits every ring style.
Emerald Cut The emerald cut is a sophisticated rectangular shape with step cut facets that create a stunning hall-of-mirrors effect. It is elegant, modern and perfect for those who prefer a sleek, architectural look.
Marquise Cut The marquise cut is a dramatic elongated shape with pointed ends that delivers a bold burst of sparkle. It creates the illusion of a much larger stone and is perfect for those who want something unique and eye-catching.
Pear Cut The pear cut combines the brilliance of a round diamond with the elegance of a marquise. Its teardrop silhouette is romantic and graceful, and it makes the finger look beautifully slim.
Princess Cut The princess cut is a square shape that delivers exceptional brilliance. Its clean geometric lines make it perfect for modern, contemporary ring styles.
Cushion Cut The cushion cut is a soft square shape with rounded corners. It has a romantic, vintage feel and delivers beautiful fire and brilliance. The elongated cushion cut is particularly popular right now.
Step 3 - Choose Your Ring Style
Once you have chosen your diamond shape, you need to decide on the ring style or setting:
Solitaire The classic solitaire setting features a single diamond as the centrepiece. It is timeless, elegant and lets the diamond take centre stage. A solitaire ring never goes out of style.
Hidden Halo The hidden halo features a ring of smaller diamonds set just below the centre stone, invisible from the front but creating a beautiful halo of light around the diamond. It adds sparkle without adding visual weight.
Pavé The pavé setting features small diamonds set closely together along the band, creating a continuous sparkle effect. It adds brilliance and luxury to any ring style.
Three Stone The three stone ring features a centre diamond flanked by two smaller diamonds on either side. It symbolises the past, present and future of your relationship and is deeply meaningful.
Nature Inspired Nature inspired rings feature organic motifs like leaves, vines and flowers. They are romantic, unique and perfect for those who love a bohemian or vintage aesthetic.
Split Shank The split shank setting features a band that splits into two as it approaches the centre stone, framing the diamond beautifully and adding visual interest.
Step 4 - Choose Your Metal
The metal you choose affects both the look and durability of your ring:
14k Yellow Gold Classic, warm and timeless. Yellow gold complements all skin tones and pairs beautifully with all diamond shapes. 14k gold is durable and affordable.
18k Yellow Gold Richer and deeper in colour than 14k. 18k gold has a higher gold content and a more luxurious appearance.
White Gold White gold has a cool, silvery appearance that makes diamonds appear brighter and more brilliant. It is the most popular metal choice for engagement rings today.
Rose Gold Rose gold has a warm, romantic pink hue that is incredibly flattering on all skin tones. It is modern, feminine and pairs beautifully with oval and pear shaped diamonds.
Platinum Platinum is the most durable and precious metal for engagement rings. It is naturally white, hypoallergenic and will never fade or tarnish. It is the premium choice for those who want the best.
Step 5 - Choose Your Diamond Quality
When selecting your diamond, focus on these four factors the 4Cs:
Cut - The most important factor. Always choose Excellent cut for maximum sparkle.
Colour - Choose F, G or H colour for a near-colourless diamond that appears perfectly white.
Clarity - VS1 or VS2 clarity gives you an eye-clean diamond at a great value.
Carat - Choose the largest carat that fits within your budget after optimising cut, colour and clarity.
With lab grown diamonds, you can typically afford a significantly larger carat weight than with natural diamonds without compromising on quality.
Step 6 - Make Sure It Is Certified
Always buy a diamond with an independent gemological certificate. At Luxumoon, all our lab grown diamonds are IGI certified giving you complete confidence in the quality and authenticity of your stone.
Never buy a diamond without a certificate from IGI or GIA.
Step 7 - Think About Her Style
The most important thing is that the ring reflects her personal style. Consider:
- Does she prefer classic or modern styles?
- Does she wear yellow gold or silver toned jewellery?
- Does she prefer minimalist or statement pieces?
- What is her lifestyle active, creative, professional?
If you are unsure, a classic oval solitaire in white gold or yellow gold is always a safe and stunning choice that suits almost everyone.
