Why Choose a La Joya Solitaire?

Because we believe you shouldn’t have to choose between your values and your vision. We combine three generations of diamond expertise with modern lab-grown technology to deliver a stone that is physically identical to a mined diamond—but brighter on your conscience and lighter on your wallet. You get the ‘La Joya’ standard: hand-selected brilliance backed by 30 years of trust. 

Custom Solitaire Engagement Ring Design

A solitaire is defined by its single stone, but the “gallery”—the area beneath the diamond—is a blank canvas. This is the perfect place to add a hidden detail without distracting from the main event. By customizing the basket or adding a unique bridge, you turn a standard solitaire into a piece of art that looks different from every angle. 

Ethical & Sustainable

Our solitaire diamond engagement rings are beautiful inside and out. By choosing a lab-created diamond, you are choosing a conflict-free stone with a minimal environmental footprint. Wear your symbol of commitment with pride, knowing it represents a modern, responsible choice for the planet. 

Unbeatable Value

Lab grown diamond engagement rings are typically 60-80% more affordable than natural mined diamonds. This value allows you to upgrade your solitaire engagement ring’s center stone size or quality significantly, giving you a larger, brighter diamond for the same budget. 

Lifetime Warranty

We stand behind the quality of our craftsmanship. Every La Joya ring comes with a lifetime manufacturing warranty to protect your investment against defects. We also offer guidance on care and cleaning to ensure your ring retains its breathtaking sparkle for a lifetime.

Content How to Choose the Perfect Solitaire Engagement Ring

Buying a solitaire engagement diamond ring may seem simple, but the details matter. From selecting the right carat weight to finding the perfect wedding band match, here are the expert tips you need to make the right choice for her forever ring. 

Choosing the Right Carat

In a solitaire engagement ring setting, the center stone stands alone, making carat size pivotal. Consider “finger coverage”: a 1-carat diamond dominates a size 4 finger but looks modest on a size 8. Leverage lab-grown affordability to maximize impact—upgrading to a 1.5 or 2-carat stone allows you to achieve perfect proportions without stretching your budget.

Matching Wedding Bands

Single diamond engagement rings offer unmatched versatility for your stacked bridal set. Their elevated settings typically allow wedding rings to sit flush, eliminating gaps. Whether you choose a seamless plain band for timeless elegance or a diamond pavé enhancer for added brilliance, a solitaire accommodates every style, ensuring a cohesive, future-proof pairing

Finding Her Ring Size

A perfect fit is essential for a comfortable single stone engagement ring. You can borrow a ring she wears on her ring finger to trace, or use our printable size guide. If you are unsure, it is better to size slightly up, as sizing down is easier than sizing up.

Care & Maintenance

Because the diamond is exposed in a solitary engagement ring, dirt can gather underneath the setting. Clean your solitaire weekly with warm water, mild soap, and a soft toothbrush. Gently brushing the underside of the stone will restore its brilliance and keep it sparkling like new.

FAQs About Lab Grown Diamond Solitaire Engagement Rings

What is a "Flush Fit" Solitaire and why does it matter?

+

Defined by its practical elegance, a flush fit solitaire features a center stone set high enough to allow a straight wedding band to sit perfectly against the engagement ring without a gap.  

This architectural detail eliminates the need for a curved contour band, offering you maximum versatility when building your future bridal stack.  

4-Prong vs. 6-Prong: Which setting is best for a round solitaire engagement ring?

+

The choice between prong settings is a balance of security and aesthetics: a 4-prong setting maximizes light entry for a modern, square look, while a 6-prong setting reinforces the diamond’s round shape for a secure, traditional ‘Tiffany-style’ silhouette 

Can I customize a solitaire engagement ring without changing its classic look?

+

Customizing a solitaire allows you to maintain the timeless ‘top view’ while personalizing the profile with discrete details like a hidden halo or gallery engraving.  

These modifications ensure the ring feels exclusively yours without altering the classic silhouette that defines the style 

 

Which solitaire diamond shape offers the most "finger coverage"?

+

For maximum visual impact, elongated shapes like Oval, Marquise, and Pear cuts are superior choices. Because these diamonds carry their carat weight on the surface rather than in depth, they appear larger than round diamonds of the same carat weight and create a flattering, lengthening effect on the wearer’s finger.  

Why is a lab-grown diamond the smart choice for a solitaire setting?

+

In a solitaire setting, the center stone is the undisputed hero, meaning clarity and cut flaws have nowhere to hide.  

Choosing a lab-grown diamond allows you to allocate your budget toward a higher clarity and color grade, ensuring the solitary stone is eye-clean and colorless, while often upgrading your carat size by 60-80% for the same price.  

What is the difference between a "Cathedral" and "Floating" Solitaire setting?

+

cathedral setting is defined by metal arches that rise to support the basket for added structural elegance, whereas a floating (or trellis) setting features an open gallery where prongs appear to stem directly from the band for a delicate, airy aesthetic 

Does a Solitaire Engagement Ring have to be a round diamond?

+

A ‘solitaire’ simply refers to a ring with a single center stone, meaning it is not restricted to the traditional round brilliant cut. Fancy shapes like EmeraldCushion, or Princess cuts are equally valid solitaire choices that offer a distinct personality while retaining the style’s minimalist elegance 

What is a solitaire engagement ring?

+

A solitaire engagement ring is a jewelry setting that features a single central gemstone mounted on a plain or detailed metal band. This iconic design places the entire visual focus on the diamond itself, minimizing distractions to highlight the stone’s cut quality, clarity, and brilliance. 

Are solitaire engagement rings boring?

+

No, solitaire engagement rings are far from boring. They are timeless canvases that allow the diamond’s natural beauty to take center stage. Their simplicity makes them the most versatile style available, as they can be completely transformed by pairing them with unique diamond bridal set bands, ring guards, or mixed-metal stacks. 

Are solitaire rings only for engagement?

+

No, while solitaire rings are the global standard for marriage proposals, they are not exclusively for engagements. They are increasingly purchased as promise rings, milestone anniversary gifts, or “right-hand rings,” serving as a symbol of personal achievement or self-love rather than just romantic commitment. 

What is a high setting solitaire engagement ring?

+

A high solitaire engagement ring refers to a mounting where the center diamond is elevated significantly above the band using long prongs or a cathedral structure. This height allows maximum light to enter the stone from all angles for intense sparkle and ensures that a straight wedding band can sit flush underneath the gem. 

What wedding band goes with a solitaire engagement ring?

+

The ideal wedding band for a solitaire engagement ring is typically a straight pavé or plain metal band, as the elevated center stone usually allows for a flush fit. Because the solitaire is so simple, it pairs effortlessly with almost any style, including curved enhancers, eternity bands, or contrasting metal colors for a trendy mixed-metal look.

Why choose a solitaire engagement ring?

+

Choosing a solitaire engagement ring guarantees a classic aesthetic that will never look outdated, regardless of future fashion trends. Beyond its beauty, the solitaire is the most practical setting for maintenance, offering easy cleaning access and a straightforward structure that makes resizing or upgrading the center stone simple. 

What is a good carat size for a solitaire engagement ring?

+

While the average solitaire engagement ring features a diamond between 1.00 and 1.25 carats, a “good” size is entirely subjective to your style and budget. However, choosing a lab grown diamond allows you to maximize your budget, often letting you purchase a 2.00-carat or larger solitaire for the price of a much smaller mined diamond.
