Online jewelry stores have made it convenient to shop rather than spending time hovering from one shop to another to buy a dream engagement ring. Today, modern trends include a custom-made diamond ring for engagement. Ring customization offers design flexibility, expresses love towards your partner, and exposes your talent. 

Choose essentials wisely when customizing a diamond ring. It is a little time-consuming but will be a one-of-a-kind ring you specifically designed for your partner. 

How to Make a Custom Engagement Ring?

The engagement ring design is easy, but you must know what to consider.

Choose the diamond 

  1. Shape: 

Center stones are available in different shapes ranging from safe round brilliant cut to square, rectangular, oval, heart, and pear shapes. Choose a trendy shape that matches the taste of your partner.

  1. Filter 4C’s:
  • Carats define the diamond’s weight. It dramatically impacts the ring’s appearance and even the price. 
  • Cut defines the shape, including emerald-cut, princess-cut, cushion-cut, baguette-cut, etc. Diamond cut impacts sparkle and brilliance.
  • Clarity determines the diamond’s visual appearance. The fewer blemishes and inclusions the stone has, the better its clarity grade. As a result, it affects the end price. 
  • Color grade ranges from colorless [D] to noticeable brown or yellow [Z]. The majority of diamond rings use grades between D to M.

Select ring style:

  1. The halo proposal ring has a medium-sized center diamond with a halo of tiny diamonds surrounding it. For a vintage look, consider a pave halo to create an art deco style. For Victorian style, consider flower and pattern halos. 
  2. Diamond bands are popular. They feature a line of diamonds across the band, adding a refined sparkle. For example, trilogy wedding rings comprise three diamonds that symbolize the past, present, and future. You can even get your fiancée the infinity ring, which signifies eternal love. 

Pick the ring metal

You get an array of metal options to tailor an engagement ring for your partner. For precious metals, choose yellow gold, platinum, or white gold. You can add uniqueness by choosing rose gold, palladium, or titanium. 

  1. Know your loved ones’ ring size

Ordering a ring that properly fits your loved one allows for avoiding resizing after you propose. However, it may be impossible with the settings. 

  1. Adding unique & personal details

Customization of a ring is a personal thing. Engraving offers to inscribe the initials of your bride-to-be or groom-to-be. You can even have an exceptional love message quote laser inscribed on the diamond. Adding subtle diamond detailing like a bridge or bezel adds a refined, romantic touch. 

Many companies like the US Company – Sunny Eden™ encourage customers to provide their ideas or ring sketches to help them create a bespoke engagement ring.

An Even More Unique Custom-Made Engagement Ring 

Lab-grown and natural diamonds have a similar crystal structure, a beautiful sparkle, and the same hardness. They are durable like natural stones but a little easier on the cost. A lab-made diamond is chemically and optically identical to a mined diamond. It is impossible to tell the difference with the naked eye. However, trained gemologists can detect the difference. The High Pressure, High Temperature [HPHT] process creates an environment similar to how natural diamonds grow under the earth’s crust. Carbon is subjected to high temperature and then pressed together. Each machine can contain only one diamond at a time in its core. 

Chemical Vapor Deposition [CVD] is another method used to create diamonds in a lab. Methane and hydrogen gas are mixed and placed inside a chamber with seed crystals. Microwave power at a high temperature heats the chamber and excites the gas pressuring the diamonds to grow on seed crystals. Man-made diamonds are created in a fully monitored, strict controlled environment. The CVD machines can contain many diamonds at a time in their core, enabling a mass production of lab-grown diamonds. 

Options for diamond colors

Diamonds’ color grade ranges from 200 to 300 shades. While grading three aspects need to be considered base color, secondary color, and intensity. Base colors include yellow, orange, red, green, pink, purple, blue, gray, brown, violet, black, and white. Hues and shades also play a crucial role when choosing fancy colors. 


Lab-created diamonds are less costly than mined diamonds because of fewer intermediaries in production and supply. The quality is generally excellent and is more affordable. The groom or the bride can buy a large diamond ring at a 30% less rate than the natural diamond ring and still stand out.

More romantic

Planning your wedding? A lab-grown diamond engagement ring made from the essence of you (and/or your partner) can add romance and a unique touch to your magical day. Diamonds from hair sound strange but are possible. Hair contains carbon, which is extracted using specialized technology in a laboratory and then grown into a real diamond. 

The HPHT method is used to make diamonds from hair carbon. Then, married couples can or may choose to wear matching rings. 

Custom Engagement Rings FAQs

How much is a custom engagement ring?

A custom engagement ring depends on the pattern complexity, diamond size, and specifications. For a fiancé buying a diamond couple’s ring can be much cheaper than ready-made ones. In addition, you can choose an independent jeweler instead of a giant brand to avoid the large overhead cost. 

How long does it take to make a custom engagement ring?

On average, the customized ring takes approximately two weeks to finish. The designing process is time-consuming because of intricate patterns or a need for multiple changes that can cause delays. After approving the final ring pattern, the creation takes a couple of days.

What is the process of making a custom engagement ring?

  • Inspiration and sketching – Check designs for inspiration online and do several sketches. Make changes according to the recipient’s style and needs. Be creative!
  • 3D modeling – Couples can gain the chance to try the 3D-printed diamond band. Pre-trying your sketched ring before ordering gives an idea if it is suitable for daily wear or not. It allows choosing preferred metal suitable to skin tone. You can find out if the diamond carat fits the personality of the other half.
  • Create wax model – following the sketch, the jeweler uses wax and carves the ring model. Next, the plaster mold is made from a wax model.
  • Casting – Desired metal is heated at extreme temperature and turned into liquid. Metal is poured into the plaster mold with a designed ring style. When metal hardens the ring’s raw casting is formed. 
  • Lapping – The ring is tapped gently with a hammer and heated to make the right size. Finally, the shape is filed and the finishing touch is given with an abrasive rubber wheel. 
  • Pre-polishing – Different grades of polishes and mops are used to polish the metal and prep the ring for setting.
  • Diamond setting – Diamonds are matched and measured before the setting process. Then special tools are used to set the diamonds on the ring surface.
  • Final polishing & more – Fine polishing compounds give a ring a brilliant look. For example, some people have white gold rings rhodium plated to avoid scratching and preserve its silvery shine. 

Bottom Line

Choosing a customized lab-grown diamond engagement ring for a proposal has its benefits. It is exceptional, and you can create a complementing wedding band to symbolize marriage vows. Choose carat size, shape, and center stone diamond quality based on the 4C’s. Choose a metal of a single color or mix it. Diamonds made in a lab environment imitate natural sparklers mined from the earth. Custom engraving in the band engraving or laser inscription in diamonds made from hair gives a personalized touch.
