Marquise Halo Diamond and Sapphire Ring
Necklaces
Here’s how you'll know exactly where the necklace will sit on your body.
General Tip: The standard length for women is usually 42-45 cm, and for men 50-55 cm.
-
Method 1: Measuring with String (Custom Fit)
Want the perfect length? Take a piece of string (any length), place it around your neck in front of a mirror, and hold it at the point that looks most flattering and suitable for your look. Mark this point (where the string ends), then place the string on a ruler to find out the exact length in cm. -
Method 2: Measuring a Favorite Necklace
Do you have a necklace that's the perfect length? Lay it open and flat on a surface and measure it from end to end with a ruler. If you're unsure, remember that thicker necklaces usually sit slightly higher than thinner necklaces of the same length.
Bracelets
A guide to finding the perfect balance between comfort and style.
Average Sizes: The average wrist circumference for women is 15-17 cm, and for men 18-21 cm.
-
Method 1: Measuring Wrist Circumference
Measure the circumference of your wrist snugly around the prominent bone using a measuring tape. To the result, add an allowance for comfort: 1 cm for a snug fit or 2 cm for a loose fit. The total sum is the size to order. -
Method 2: Measuring an Existing Bracelet
Do you have a bracelet that fits you perfectly? Lay it open and flat on a ruler and measure it from end to end (including the clasp). The length you get in cm is the exact size.
Rings
Two simple ways to find the precise size, so the ring fits you perfectly.
-
Method 1: Measuring with a Flexible Tape
Don't have a suitable ring for your hand? Wrap your finger with a measuring tape (or a strip of paper) comfortably but snugly. Mark the meeting point and check the length in millimeters against the size chart on the website. -
Method 2: Measuring an Existing Ring (The Quick Method)
Take a ring that fits you well, place it on a ruler, and measure only the inner diameter (the empty space, without the walls). Compare the result to our table.
Earrings
Two simple and accurate ways to find your size from home, to choose the exact presence you're looking for.
-
Method 1: Carat Check and Accurate Calculation
Place the earring on a ruler and measure the diamond's diameter in mm. Instead of relying on a general chart, ask Google or AI: "How many carats does a diamond with a diameter of [your measurement] mm weigh?" to get the most accurate answer. Want a specific size? Mention it in the order notes and we will custom-make the earring for you. -
Method 2: Size Comparison and Visualization on the Ear
A close-up photograph can be misleading. To help you understand the true proportions, we've created a simulation showing different diamond sizes (from 0.25 to 3 carats) on the same ear. This way you can choose if you're looking for a delicate and minimalist look or a prominent and luxurious one.
Order with Peace of Mind
It's important to us that the jewelry feels like it was created especially for you.
If after measuring at home you feel the need for a slight adjustment, we will gladly perform the first size adjustment for free. You will only pay for shipping, and we will take care of the rest.

This ring was built around a precise layered structure – a central marquise diamond surrounded by a halo that accentuates its elongated shape, and a sapphire stone set within the band that adds depth of color and clear contrast.
There is a combination here of classicism and an unexpected structure. The marquise catches the eye with a sharp line, the halo enhances its presence, and the sapphire creates an additional layer that reveals itself with movement.
This is a piece of jewelry that is felt through structure, light, and color – not through clutter.
This is a piece one chooses to wear when seeking a complex presence with a clear personal signature.
Diamonds and Stone: Central marquise diamond of approx. 1.50 carats with a diamond halo, alongside a blue sapphire stone set in the band.
Total Weight: Approx. 2.10 carats (TCW) of lab-grown diamonds (CVD) and gemstones.
Materials: 14K solid gold (yellow, white, or rose), with careful setting emphasizing the stone's structure.

What are they saying about us
4.9/5 based on +150 verified reviews

Latin roots, Israeli precision
Our journey begins on the shores of South America and arrives to you precisely as blue and white. Our pieces are an anchor of freedom – a natural connection to the wild spirit of the sea, even in the midst of urban routine.

Strong in the waves
Our pieces are designed to live with you from the sea to the bar, without you feeling the need to take them off. Cast in 925 sterling silver and solid gold with extra-strong clasps, to withstand all conditions and give you peace of mind.

Asymmetric completeness
The most powerful beauty lies outside the straight lines. In every piece, we've incorporated a small, deliberate "disruption" that breaks the flow – an elegant reminder of the "quirk" and imperfect nature of all of us. This touch is what makes each piece one-of-a-kind.


How your Piece arrives
The piece is carefully packaged in our luxurious hard case, inside a natural canvas pouch, and accompanied by a personalized letter and warranty card. A perfect gift with presence – whether for yourself or a loved one.
