Some of the most common occasions include the engagement ring, wedding band and diamond pendant for the birth of a child

The engagement ring

It is the diamond jewel par excellence. And for many, the first purchase of a diamond. As a symbol of the rarity and uniqueness of love, a man usually gives a solitaire ring, with a single diamond set in the center. Among all the precious stones, the diamond carries the brilliance and strength of love to the highest level. The mission of the solitaire setting is to highlight the diamond as much as possible. Hence the perennial success for decades of the classic diamond solitaire with claws (4, 5 or 6 claws) whose light and timeless style enhances the fire of the stone set in its center. Most of the diamond solitaires are made with a brilliant cut diamond, whose majesty has never been surpassed by any other cut. The round shape remains the cut that gives the most brilliance to a diamond by the play of facets.

The wedding ring

There is no wedding without a wedding ring, symbol of eternal love thanks to its ring shape without beginning and without end. There are multiple models of wedding rings: all gold without any stone, set with fine stones or precious stones. But the most symbolic is the diamond wedding ring because it signifies the rarity of the union. For this jewel, all forms of diamonds are used. The round brilliant diamond remains the most common choice for wedding rings, but we also make a lot of wedding rings with princess, emerald, heart cut diamonds... An alternation of stone shapes is also possible, with for example an alternation of round diamonds and baguette diamonds. The combinations are multiple. That said, the brilliant cut diamond remains by far the most sparkling, so it is preferable if you are looking primarily for the brilliance of the setting.

The diamond pendant

It is often offered as a gift at the time of a daughter's birth because it has the advantage of being able to be passed on from mother to daughter (at her 18th birthday) without worrying about being cut. On this occasion, the father usually offers a solitaire diamond pendant. The diamond is then the main part of the pendant, and the setting wants to be as discreet as possible to emphasize the brilliance of the stone. Hence the great success of diamond pendants with claws (3 or 4 claws). With its timeless and elegant design, this type of setting goes beautifully with all types of outfits, and especially with suits.
